⚕️ FREE MSRA PODCAST – Squamous Cell Carcinoma (SCC)
🎧 A high-yield breakdown of this common but potentially serious skin cancer – essential for MSRA prep and clinical practice.

🧠 Key Learning Points

📌 Definition
• SCC is a malignant tumour of squamous cells in the epidermis.
• It is the second most common non-melanoma skin cancer and has metastatic potential.

📌 Causes & Risk Factors
• Chronic UV radiation exposure ☀️
• Fair skin, older age, male gender
• Immunosuppression (e.g. transplant patients, HIV)
• Chronic inflammation (old burns, scars, ulcers)
• Exposure to arsenic or past radiotherapy
• Premalignant lesions (actinic keratosis, Bowen’s disease)
• Genetic conditions (xeroderma pigmentosum, albinism)
💡 Mnemonic: "SUN BURN" – Sun, Ulcers, Neoplasia in situ (Bowen's), Burns, UV, Radiotherapy, Nevus (genetic)

📌 Pathophysiology
• UV-induced DNA mutations → dysregulated squamous cell growth
• Tumour invades dermis, then lymphatics or blood → local/distant spread
• Risk factors amplify mutation accumulation

📌 Symptoms
• Firm, red nodule or scaly ulcer that won’t heal
• Can bleed easily, ulcerate or crust over
• Typically found on sun-exposed areas: face, ears, lips, scalp, hands
• May arise from actinic keratosis or Bowen’s disease

📌 Differential Diagnosis
• Keratoacanthoma
• Basal cell carcinoma (pearly appearance)
• Amelanotic melanoma
• Actinic keratosis
• Pyogenic granuloma
• Warts or chronic verrucae (esp. periungual)

📌 Diagnosis
• Clinical suspicion + histological confirmation via biopsy
• Excisional or punch biopsy preferred
• Imaging (CT/MRI) if deep invasion suspected
• Always refer suspected cases via 2-week wait pathway

📌 Management
• Surgical excision with clear margins (4–6mm depending on size)
• Mohs surgery for high-risk or cosmetically sensitive areas
• Cryotherapy or curettage for superficial lesions
• Radiotherapy if surgery contraindicated
• Topical 5-FU or Imiquimod for SCC in situ (Bowen’s disease)
• MDT involvement for advanced or recurrent disease

📌 Complications
• Local invasion (e.g. lip, eye, cartilage, bone)
• Perineural spread (causing pain or numbness)
• Lymphatic or haematogenous metastasis (lungs, liver, brain)
• Cosmetic disfigurement, post-surgical scarring

📌 Prognosis
• Excellent with early diagnosis and complete excision
• Poorer outcomes if: lesion >20mm, depth >2–4mm, poor differentiation, perineural invasion, immunosuppressed, lip/ear site
• Most recurrences within first 2 years – regular follow-up vital

⚕️ FREE MSRA PODCAST – Pemphigoid Gestationis
🎧 A clear, high-yield breakdown of this rare autoimmune blistering condition in pregnancy – perfect for exam prep and clinical diagnosis confidence.

🧠 Key Learning Points

📌 Definition
• Pemphigoid Gestationis (PG) is a rare autoimmune subepidermal blistering disorder that occurs during pregnancy, usually in the 2nd or 3rd trimester.
• It involves IgG1 autoantibodies attacking the basement membrane zone of the skin.

📌 Causes & Risk Factors
• Pregnancy-related immune shifts (autoimmune trigger)
• Linked to hydatidiform mole or choriocarcinoma
• HLA-DR3 and HLA-DR4 associations
• Family or personal history of autoimmune disease
🧠 Mnemonic: “GHOST” – Gestation, HLA-DR3/4, Onset late, Skin attack, Thyroid risk

📌 Pathophysiology
• IgG1 antibodies bind to antigens in the lamina lucida → activate complement (C3)
• Leads to inflammation and dermal-epidermal separation
• Creates subepidermal bullae
• Shares antigenic similarities with bullous pemphigoid

📌 Symptoms
• Severe pruritus – hallmark feature, often before rash
• Begins with urticarial plaques (esp. periumbilical) → evolves into tense blisters
• Spares face, palms, soles, and mucosa in most cases
• Often worsens postpartum, but resolves over weeks/months
• May recur with future pregnancies, OCPs or menstruation

📌 Differential Diagnosis
• PUPPP (more common, lacks blisters)
• Bullous pemphigoid
• Linear IgA dermatosis
• Dermatitis herpetiformis
• Pruritic folliculitis of pregnancy
• Erythema multiforme

📌 Diagnosis
• Clinical picture + skin biopsy (from lesion edge)
• Direct immunofluorescence (DIF): linear C3 deposits at basement membrane
• Indirect immunofluorescence (IDIF): circulating IgG autoantibodies (PG factor)
• HLA-typing (supportive, not diagnostic)
🧠 Tip: DIF = deposits in skin, IDIF = antibodies in blood

📌 Management
• Oral corticosteroids (prednisolone 0.5–1 mg/kg/day) – mainstay
• Antihistamines – symptomatic relief for pruritus
• Emollients for skin comfort
• Severe/resistant cases: consider plasmapheresis or immunoadsorption
• Multidisciplinary care: dermatologist + obstetrician + paediatrician

📌 Complications
• Preterm labour (~20%)
• Small-for-gestational-age (SGA) infants
• Neonatal blisters (5–10%): transient, due to maternal IgG crossing placenta
• Psychological distress, sleep disruption from pruritus

📌 Prognosis
• Self-limiting postpartum, but may recur in future pregnancies or hormonal shifts
• Increased lifelong risk of autoimmune disease (e.g. Graves’, Hashimoto’s, Pernicious anaemia)
• Important for long-term autoimmune screening and counselling

🎧 MSRA Deep Dive: Shingles – High-Yield Revision Essentials
Get exam-ready with this concise breakdown of shingles (herpes zoster) – covering pathophysiology, risk factors, red flags, and NICE-aligned management. Perfect for MSRA prep! 🧠

🧠 Core Learning Points

📌 Definition
• Reactivation of latent Varicella-Zoster Virus (VZV)
• Causes painful, unilateral, vesicular rash in a dermatomal pattern
• Commonly affects thoracic dermatomes or cranial nerves

📌 Pathophysiology
• After chickenpox, VZV lies dormant in sensory dorsal root ganglia
• Reactivation → virus travels along nerve → dermatomal rash
• Triggered by immunosuppression, age, stress
🧠 Mnemonic: “VIRUS” – VZV Reactivation In Unilateral Segment

📌 Risk Factors
• Age >50
• HIV (15x increased risk)
• Chemotherapy, immunosuppressants, long-term steroids
• Bone marrow transplant, lymphoma
• Stress
• Hx of chickenpox is a prerequisite

📌 Clinical Features
Prodrome (2–3 days):
– Burning/tingling pain
– Fever, malaise, local lymphadenopathy

Eruptive Phase:
– Red → vesicular → crusting rash in one dermatome
– Does not cross midline
– Lasts 2–4 weeks
– Ophthalmic zoster: affects eye – URGENT referral

Postherpetic Neuralgia (PHN):
– Pain lasting ≥30 days after rash resolves
– Risk ↑ with age

📌 Differentials
• HSV
• Contact dermatitis
• Eczema herpeticum
• Impetigo
• Insect bites
• Migraine/angina (if prodrome only)

📌 Infectivity & Transmission
• Shingles = not contagious as shingles
• VZV from blister fluid can cause chickenpox in non-immune individuals
• Avoid contact with:
– Pregnant women without immunity 🤰
– Neonates 👶
– Immunocompromised 💉

📌 Investigations
• Clinical diagnosis is usually sufficient
• Consider PCR of vesicle fluid if:
– Atypical features
– Immunocompromised patient
– Disseminated or severe disease
• IgM, Tzanck smear (older method) rarely used
• Eye involvement → urgent ophthalmology assessment

📌 Management (NICE/CKS aligned)

💊 Antivirals (start within 72h ideally):
• Aciclovir, valaciclovir, famciclovir
• Give to:
– Adults >50
– Immunocompromised
– Severe pain or non-truncal involvement
🕒 Start even after 72h if high-risk or ongoing vesicle formation

💥 Pain Relief
• 1st line: Paracetamol ± NSAIDs
• 2nd line: Amitriptyline, gabapentin, pregabalin, duloxetine
• Topical lidocaine patches may help
• Corticosteroids: reserved for severe acute pain (selected adults)

👁️ Referral Needed If:
• Ophthalmic zoster
• Immunocompromised
• Disseminated rash or complications
• Neurological signs (e.g., meningitis)
• Pregnant women
• PHN – consider pain clinic

📌 Complications
• PHN – burning nerve pain (up to 30% in older adults)
• Ophthalmic zoster – uveitis, keratitis, vision loss
• Ramsey Hunt syndrome – facial paralysis, ear pain, hearing loss
• Skin scarring, pigmentation
• Secondary infection
• Neurological – meningitis, encephalitis, myelitis
• Disseminated zoster – esp. in immunocompromised

📌 Prognosis
• Most recover in 2–4 weeks
• PHN may persist for months/years
• Early antiviral treatment = ↓ PHN risk
• Mortality rare – mainly in immunocompromised

📌 Vaccination
• Shingles vaccine (Shingrix) offered to older adults to reduce risk
• Chickenpox vaccine not routine in UK (due to theoretical effects on herd immunity)

✅ MSRA Deep Dive: Seborrhoeic Keratoses – Spotting the Harmless vs. the Harmful

In this revision-focused episode, we dive into seborrhoeic keratoses (SKs) – one of the most common skin findings in clinical practice and exams. Although benign, they’re frequently confused with serious lesions like melanoma or basal cell carcinoma (BCC). We clarify what they are, how to spot them, and when to worry.

🧠 Key Learning Points

📌 Definition
• Common, benign epidermal tumours, often seen in older adults
• Have a characteristic “stuck-on”, waxy or wart-like appearance
• Also known as seborrheic warts

📌 Causes & Risk Factors
• Exact cause unknown
• Age is the strongest factor – more common with increasing age
• Genetic predisposition plays a role
• Sun exposure may be a contributing factor, but not directly causative
• Associated with other findings like dermatosis papulosa nigra (especially in darker skin types)

🔬 Pathophysiology
• Benign proliferation of immature keratinocytes in the epidermis
• Mutation in FGFR3 gene has been associated
• Not related to infection or malignancy

👨‍⚕️ Clinical Features
• Well-circumscribed, raised lesion with waxy, rough, or verrucous surface
• Colour: Tan, brown, black, or grey
• Typically painless, but may be itchy or irritated
• Most common on the trunk, face, scalp, or back
• Described as having a “stuck-on” look – as if pasted onto the skin
• May crumble if picked and can appear greasy

⚠️ Differential Diagnoses
• Melanoma – esp. nodular or amelanotic types
• Basal cell carcinoma (BCC) – esp. pigmented or nodular BCC
• Actinic keratosis – usually flatter and rougher, with sun-damaged background skin
• Key distinction: asymmetry, irregular borders, colour variation, ulceration, or bleeding → consider biopsy

🧪 Diagnosis
• Primarily clinical – classic appearance is diagnostic
• Dermoscopy can help – features like milia-like cysts and comedo-like openings
• If uncertain or atypical features → biopsy is necessary to rule out malignancy

💊 Management
• No treatment required if asymptomatic and diagnosis is clear
• Indications for removal:
– Cosmetic concern
– Persistent itching or irritation
– Secondary infection or bleeding
• Removal options:
– Cryotherapy (freezing)
– Curettage (scraping)
– Electrosurgery
– Laser ablation
• Avoid removal unless confident in diagnosis or malignancy ruled out

📈 Prognosis
• Excellent – SKs are completely benign
• Treated lesions don’t recur, but new lesions may develop in predisposed individuals
• No malignant potential, but important not to misdiagnose melanoma or BCC as SK

⚠️ Complications
• Not due to the lesion itself, but secondary to irritation
• Rubbing on clothing may cause itching, bleeding, or inflammation
• Picking or trauma may lead to infection
• Cosmetic distress in visible locations may impact quality of life

💡 MSRA Tip
If you're faced with a pigmented lesion that looks “stuck on” and waxy – think SK.
But always ask yourself:
🧐 “Is there any possibility this could be melanoma or BCC?”
If yes → biopsy.

🎯 Everything you need to revise seborrhoeic dermatitis in adults for the MSRA. Cut through the noise—covering causes, clinical features, management, differentials, and more.

Key Learning Points

🔍 Definition
• Seborrhoeic dermatitis is a chronic, relapsing inflammatory skin disorder affecting oily areas—scalp, face, chest
• Linked to the yeast Malassezia; not contagious

💡 Causes & Risk Factors
• Overgrowth or sensitivity to Malassezia yeast
• Sebaceous gland activity (oily skin)
• Family history, stress, immunosuppression (HIV, Parkinson’s), winter, hormonal changes
• Aggravated by illness, fatigue, medications

🧬 Pathophysiology
• Overreaction of immune system to Malassezia yeast on sebum-rich skin
• Inflammation → increased turnover → greasy yellow scales, redness, itch

🩺 Clinical Features
• Greasy, yellowish scales over red, itchy patches
• Affects scalp (dandruff), eyebrows, nasolabial folds, central face, chest, upper back, flexures
• Worse in winter; flares/remissions
• Often chronic but manageable

📝 Differential Diagnosis
• Psoriasis (thick, silvery scales, extensor surfaces)
• Atopic dermatitis, contact dermatitis, tinea capitis/versicolor, rosacea, lupus, candidiasis

🔬 Diagnosis
• Clinical—based on typical rash and distribution
• Fungal scrapings or biopsy only if diagnosis is unclear

💊 Management
• Topical antifungals: ketoconazole, ciclopirox (creams, shampoos)
• Topical corticosteroids for flares (short term only, low-potency for face)
• Maintenance with antifungal shampoos
• Calcineurin inhibitors (tacrolimus, pimecrolimus) as steroid-sparing options
• Severe/atypical cases: screen for HIV
• Rare: systemic antifungals, oral tetracyclines, isotretinoin

📈 Prognosis
• Chronic, relapsing-remitting; no cure but usually controllable
• Significant impact on quality of life, but rarely causes serious complications
• Risk of secondary infection if scratched/broken skin

⚕️ FREE MSRA PODCAST – Sebaceous Cysts
🎧 A clear, high-yield breakdown of these common benign skin lumps – ideal for clinical recognition and MSRA prep!

🧠 Key Learning Points

📌 Definition
• Sebaceous cysts (often epidermoid or pillar cysts) are non-cancerous, subdermal lumps
• Typically filled with keratin or sebum and found under the skin

📌 Causes & Risk Factors
• Blocked hair follicles or sebaceous glands
• Minor trauma, acne, hormonal changes
• Risk factors: oily skin, family history, acne
• 🧬 Gardner Syndrome: multiple early-onset cysts + bowel polyps + osteomas = RED FLAG

📌 Pathophysiology
• Blocked duct or follicle → buildup of keratin/sebum
• Forms a closed sac → enlarges over time
• Infection can occur → cyst becomes red, tender, swollen

📌 Symptoms
• Painless, mobile, dome-shaped lump
• Common sites: scalp, face, neck, back
• Central punctum often visible
• If ruptured: foul-smelling cheesy material
🧠 Mnemonic: PCP – Painless, Cheesy, Punctum

📌 Differential Diagnosis
• Lipoma: soft, deep, larger
• Neurofibroma: firm, multiple → consider NF1
• Abscess: red, hot, fluctuant
• Gardner’s syndrome: multiple facial/extremity cysts in young

📌 Diagnosis
• Clinical – based on appearance and history
• Ultrasound if deep or suspicious
• MRI for scalp cysts or if intracranial extension suspected
• Excision biopsy if atypical or growing fast
🚫 Fine needle aspiration NOT usually needed

📌 Management
• No treatment needed if asymptomatic
• If infected: incision & drainage + antibiotics
• Definitive treatment = surgical excision
→ Must remove entire cyst capsule to prevent recurrence
• Always send excised cysts for histology
🧠 Mnemonic: SEC – Symptomatic, Esthetic, Complicated

📌 Complications
• Infection → abscess
• Rupture → inflammation, recurrence
• Scarring post-excision
• Rare: intracranial extension (especially with scalp cysts)

📌 Prognosis
• Excellent with full excision
• Recurrence rare if capsule removed completely
• Malignant transformation is extremely rare

⚕️ FREE MSRA PODCAST – Scabies
🎧 A clear, high-yield breakdown of this intensely itchy parasitic skin infestation – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Scabies is a contagious skin infestation caused by the mite Sarcoptes scabiei var. hominis that burrows into the epidermis, triggering an allergic hypersensitivity reaction.

📌 Causes & Risk Factors
• Prolonged skin-to-skin contact
• Institutional living (e.g. nursing homes, prisons)
• Poverty, overcrowding, malnutrition, immunosuppression
• Sexual contact
💡 Mnemonic: “Close, Crowded, Compromised” for common risk factors

📌 Pathophysiology
• Female mite burrows into stratum corneum, lays eggs
• Mite products (eggs, saliva, faeces) provoke delayed-type hypersensitivity reaction
• In crusted scabies, mite load can reach millions, leading to extreme symptoms and infectivity

📌 Symptoms
• Severe pruritus, worse at night
• Widespread erythematous papules, vesicles or pustules
• Burrows: wavy, silvery lines in finger webs, wrists, genitalia
• Scabies nodules: chronic allergic lumps
💡 Mnemonic: “ITCH”: Intense, Typical sites, Crusted variant, Hypersensitivity

📌 Differential Diagnosis
• Eczema (atopic/contact)
• Insect bites
• Tinea corporis
• Psoriasis
• Lichen planus
• Impetigo (secondary infection)

📌 Diagnosis
• Clinical diagnosis via distribution, itching history, visible burrows
• Microscopy of skin scraping: mites, eggs, or faeces
• Dermatoscopy: Delta wing sign (mite at end of burrow)
• Ink burrow test
• IACS Criteria (Confirmed, Clinical, Suspected)

📌 Management
• Treat all close contacts simultaneously
• Permethrin 5% cream: first-line, whole body application
• Malathion 0.5% liquid: second-line
• Oral ivermectin for crusted scabies
• Repeat treatment after 7–10 days
• Hygiene: Wash clothes/bedding >50°C, seal non-washables for 72h
• Antihistamines, topical steroids for itch relief
• STI screening and public health notification if outbreak

📌 Complications
• Secondary bacterial infection: impetigo, cellulitis, sepsis
• Crusted scabies: high mite burden, resistant to treatment
• Psychological distress: insomnia, stigma
• Persistent itch and nodules after eradication

📌 Prognosis
• Excellent with correct diagnosis and treatment
• Delayed or incorrect treatment → reinfection, complications
• Crusted scabies: poorer prognosis, needs specialist input

A focused, exam-oriented breakdown of rosacea: features, subtypes, triggers, management, and complications – perfect for your MSRA prep.

🧠 Core Learning Points

📌 Definition
• Chronic inflammatory skin condition
• Affects the central face – redness, flushing, visible vessels, papules, pustules
• May include eye involvement or rhinophyma

📌 Subtypes & 2016 Classification
• Papulopustular – spots + redness
• Erythematotelangiectatic – flushing + telangiectasia
• Phymatous – skin thickening (e.g. rhinophyma)
• Ocular rosacea – dry, gritty, irritated eyes
• Uses ARSCO criteria: diagnostic, major & secondary features

📌 Causes & Triggers
• Multifactorial: genetics, immune dysfunction, Demodex mites
• Triggers include:
– UV exposure ☀️
– Stress 😥
– Alcohol 🍷
– Spicy food 🌶️
– Temperature extremes 🔥❄️
– Caffeine, vasodilator meds
🧠 Mnemonic: SHAUVES – Stress, Heat, Alcohol, UV, Vasodilators, Exercise, Spices

📌 Risk Factors
• Fair-skinned women aged 30–60
• Family history
• High UV exposure
• Triggering lifestyle habits

📌 Pathophysiology
• Chronic cutaneous inflammation + vasodilation
• Immune dysregulation → redness, bumps, sensitivity
• Trigger exposure → flare-up cycle

📌 Differentials
• Acne vulgaris – but rosacea skin is dry/sensitive
• Seborrhoeic dermatitis
• SLE (malar rash)
• Perioral/contact dermatitis
🧠 Dry skin + central facial redness = think rosacea

📌 Epidemiology & Diagnosis
• ~10% in UK (underdiagnosed)
• Diagnosis is clinical – ≥3 months of symptoms
• Consider biopsy/bloods if unclear or atypical features

📌 Clinical Features
• Persistent central redness, flushing, telangiectasia
• Papules/pustules, nodules, dry/burning/stinging skin
• Ocular signs – blepharitis, keratitis
• Severe swelling: Morbihan disease
• Nasal thickening: Rhinophyma

📌 Management (NICE/CKS aligned)

🧴 Lifestyle
• Avoid triggers (heat, alcohol, sun)
• Gentle skincare
• Daily SPF – oil-free sunscreen
🚫 Avoid topical steroids on the face

💊 Topical treatments
• Metronidazole, azelaic acid, ivermectin
• Brimonidine/oxymetazoline – reduce flushing

💊 Oral treatments
• Tetracyclines – doxycycline (anti-inflammatory dose)
• Low-dose isotretinoin – severe cases
• Consider clonidine/carvedilol for flushing

👁️ Ocular rosacea
• Lid hygiene, artificial tears, oral tetracyclines
• Avoid retinoids/steroids

💡 Other treatments
• Laser/IPL – telangiectasia
• Referral – derm (severe/rhinophyma), ophthal (ocular)
• Surgery/laser – for advanced phymatous cases

📌 Prognosis & Complications
• Chronic, relapsing – flares + remissions
• Trigger avoidance & early treatment key
• Complications:
– Ocular damage (if untreated)
– Rhinophyma (physical disfigurement)
– Psychosocial impact – anxiety, distress, low self-esteem

🩹 FREE MSRA PODCAST – Pyoderma Gangrenosum: Pattern Recognition, Exclusion & Immunosuppression
🎯 Everything you need to revise PG for the MSRA. From clinical recognition to management pearls—get the exam gold fast.

Key Learning Points

🔍 Definition
• Pyoderma gangrenosum (PG) is a rare, inflammatory, non-infectious skin disorder
• Presents as a painful, rapidly progressing ulcer, most often with undermined, violaceous borders

💡 Causes & Risk Factors
• Unknown aetiology—thought to be immune system dysregulation
• Pathergy: minor trauma can trigger or worsen lesions
• 50% associated with underlying disease:
 • Inflammatory bowel disease (Crohn’s/UC)
 • Rheumatoid arthritis, SLE
 • Haematological malignancies (e.g. leukaemia, lymphoma)
• More common in adults (peak >50y), slight female predilection

🧬 Pathophysiology
• Dysfunctional neutrophil response—immune “friendly fire” damages tissue
• Pathergy: skin injury → ulcer forms or worsens

🩺 Clinical Features
• Rapidly enlarging, painful ulcer with undermined, violaceous or erythematous edges
• Often starts as a pustule or nodule
• Most common on lower legs, but can occur anywhere
• May be associated with systemic symptoms (fever, malaise)

📝 Memory Tip: PUB
Painful Ulcer with Boggy Undermined Borders
PG = PUB!

💡 Variants
• Classic (most common): rapidly progressive leg ulcers
• Peristomal: around stoma sites (esp. in IBD)
• Vegetative: superficial plaques, less aggressive
• Bullous: blisters/erosions, linked to haematological disease
• Pustular: multiple pustules, often with IBD flares

🔬 Diagnosis
• Clinical + exclusion of other causes (infection, vasculitis, malignancy)
• Biopsy: rules out other conditions (not diagnostic for PG itself)
• Bloods: FBC, ESR, CRP, rheumatology screen
• Swabs/cultures to exclude infection

💊 Management
• Systemic immunosuppression: steroids are 1st line (oral prednisolone), cyclosporin, infliximab or other biologics for refractory cases
• Topical steroids for mild cases
• Wound care: essential, but avoid surgery or debridement during active inflammation (can worsen PG via pathergy)
• Treat underlying disease (e.g. IBD, RA)
• Multidisciplinary approach: dermatology, rheumatology/gastro, wound care nurses

📈 Prognosis & Complications
• Can heal with scarring; recurrence common
• Complications: chronic wounds, superadded infection, scarring, rare extracutaneous neutrophilic disease
• Prognosis tied to underlying disease and response to treatment

⚕️ FREE MSRA PODCAST – Purpura
🎧 A clear, high-yield breakdown of this essential skin sign – perfect for exam prep and spotting urgent clinical clues.

🧠 Key Learning Points

📌 Definition
• Purpura refers to purple/red skin or mucosal spots caused by bleeding under the skin.
• Non-blanching and due to vessel rupture, platelet dysfunction, or coagulation problems.

📌 Causes & Risk Factors
• Thrombocytopenic: ITP, leukaemia, DIC, bone marrow failure
• Non-thrombocytopenic: Vasculitis (e.g. HSP), scurvy, trauma, drugs
• Infections: meningococcal sepsis, streptococcal
• Ageing skin (senile purpura), steroid use
🧠 Mnemonic: V.I.P. Causes Purpura – Vessels, Infection, Platelets

📌 Pathophysiology
• Capillary rupture → blood leaks into skin
• May be due to low platelet count, vessel inflammation, or clotting factor defects

📌 Symptoms
• Petechiae (<1 cm), ecchymosis (>1 cm)
• Often asymptomatic but may be painful or tender
• Look for systemic signs: fever, joint pain, bleeding elsewhere

📌 Differential Diagnosis
• Bruising (trauma)
• Erythema multiforme
• HSP (palpable purpura)
• Coagulation disorders (e.g. haemophilia)
• DIC, drug reactions, vasculitis, factitious purpura

📌 Diagnosis
• Full Blood Count: platelet count
• Coagulation screen
• CRP/ESR, LFTs, autoantibodies, blood cultures (if infection suspected)
• Use the glass test – purpura won’t blanch under pressure

📌 Management
• Treat the underlying cause – purpura is a sign, not a disease
• Antibiotics for sepsis
• Steroids or immunosuppressants for vasculitis or ITP
• Platelet transfusion if count <20 x 10⁹/L
• Supportive: limb elevation, compression, avoid IM injections

📌 Complications
• Significant bleeding → anaemia
• Organ damage (in vasculitis)
• Delayed treatment in infections (e.g. meningococcal sepsis) = life-threatening

📌 Prognosis
• Excellent if underlying cause is treated early
• Guarded if linked to malignancy, autoimmune, or sepsis
• Chronic purpura may recur depending on trigger
