⚕️ FREE MSRA PODCAST – Impetigo
🎧 A clear, high-yield breakdown of this contagious bacterial skin infection in kids – perfect for exam prep and real-life diagnosis.

🧠 Key Learning Points

📌 Definition
Impetigo is a highly contagious superficial bacterial skin infection, most common in young children, causing honey-coloured crusted lesions, especially on the face.

📌 Causes & Risk Factors
• Staphylococcus aureus (most common)
• Streptococcus pyogenes
• Minor skin injuries: cuts, insect bites, eczema
• Warm, humid climates
• Crowded settings (e.g. nurseries)
• Poor hygiene
• Immunosuppression
🧠 Mnemonic: “HOT KIDS” – Hygiene poor, Open skin, Tropics, Kids, Infections, Direct contact, Staph/Strep

📌 Pathophysiology
• Bacteria enter via broken skin
• Staph toxins damage keratinocytes → vesicles → rupture → crusting
• Spreads via scratching or contact with infected fluid or contaminated objects

📌 Symptoms
• Golden honey-coloured crusts on red base
• Often starts on the face (nose, mouth), but can affect limbs
• Itchiness, mild pain
• Regional lymphadenopathy (especially in non-bullous form)

📌 Differential Diagnosis
• Scabies
• Contact dermatitis
• Herpes simplex
• Chickenpox/shingles
• Bullous pemphigoid
• Cellulitis
• Atopic eczema
• Stevens-Johnson syndrome
• Erythema multiforme

📌 Diagnosis
• Clinical diagnosis based on appearance and history
• Swabs: only if
– Infection is severe/recurrent
– Suspected MRSA
– Fails to respond to treatment
– Recurrent cases → consider nasal swab for staph carriage

📌 Management
• Prevent spread: hygiene, no sharing towels, avoid scratching
• Localised, non-bullous:
– First-line: Hydrogen peroxide 1% cream
– Alternatives: Topical fusidic acid or mupirocin
• Widespread or bullous OR systemically unwell:
– Oral flucloxacillin (1st line)
– Alternatives: Clarithromycin/erythromycin if penicillin allergic or pregnant
• MRSA suspected: tailor based on sensitivities
• Recurrent: consider decolonisation if nasal carriage confirmed

📌 Complications
• Cellulitis
• Lymphadenitis
• Abscess
• Staph scalded skin syndrome (rare)
• Sepsis (rare)
• Post-streptococcal glomerulonephritis
• Acute rheumatic fever

📌 Prognosis
• Excellent with prompt treatment
• Resolves in 2–3 weeks with appropriate antibiotics and hygiene
• Untreated = prolonged infection and increased spread risk

💡 FREE MSRA PODCAST – Hyperhidrosis: The Sweating You Can’t Ignore
💦 High-yield revision audio covering causes, clinical clues, and management of excessive sweating for MSRA & clinical practice.

Key Learning Points

🔍 Definition
• Hyperhidrosis = sweating in excess of physiological needs for thermoregulation
• Usually affects palms, soles, underarms, face; can be localised (focal) or generalised

🗂️ Types

1. Primary focal:
    – Idiopathic (no underlying disease)
    – Commonest, often begins in childhood/adolescence
    – Affects specific sites (hands, feet, axillae, face)

2. Secondary focal/generalised:
    – Caused by underlying condition (e.g., infection, endocrine disease, drugs, malignancy)
    – May be generalised (whole body) or focal

🦠 Causes & Risk Factors
• Primary: Family history, possible genetic predisposition
• Secondary: Infections (TB, endocarditis), hyperthyroidism, menopause, diabetes, anxiety, drugs (antidepressants, propranolol), malignancy, neurological causes
• Risk factors: Family history, chronic disease, certain medications

🧬 Pathophysiology
• Primary: Overactivity of eccrine sweat glands—autonomic nervous system dysfunction
• Secondary: Triggered by underlying pathology (hormonal, metabolic, neural)

🩺 Differential Diagnosis
• Thyrotoxicosis, menopause, infection (e.g., TB), medication side effects, anxiety, fevers, malignancy

🧑‍⚕️ Diagnosis
• Primary: Clinical diagnosis—symmetrical, started young, no night sweats, positive family history
• Secondary: Asymmetrical/generalised, new in adults, night sweats, other systemic features
• Investigations: Only if secondary suspected (FBC, TFTs, glucose, CRP/ESR, CXR, HIV, etc.)

📝 Management
🟢 Primary focal (stepwise):

1. Lifestyle: Avoid triggers (heat, spicy food, caffeine), breathable clothing, absorbent pads

2. First-line: Topical aluminium chloride (20%) at night

3. Specialist referral:
    – Iontophoresis (hands/feet)
    – Botulinum toxin (Botox) (axillae, hands, feet)
    – Oral anticholinergics (e.g., propantheline bromide)
    – Glycopyrronium (may be used in iontophoresis)

4. Surgical: Endoscopic thoracic sympathectomy (ETS), suction curettage, laser, MiraDry (for severe cases)
   🧠 Mnemonic: AIB
   Aluminium chloride, Iontophoresis, Botulinum toxin

🟠 Secondary:
• Identify & treat underlying cause
• May require specialist referral

🧑‍🤝‍🧑 Psychological Support:
• Consider CBT, address mental health impact early

📈 Prognosis
• Primary = usually lifelong but can improve with age; secondary = depends on underlying cause
• Good symptom control possible with treatment

⚠️ Complications
• Skin maceration, secondary infections (bacterial, fungal), odour, eczema/dermatitis, major psychosocial impact

💡 FREE MSRA PODCAST – Hirsutism & Hypertrichosis Explained
🪒 A focused revision audio on excess hair growth: causes, clues, and when it’s more than cosmetic.

Key Learning Points

🔍 Definition
• Hirsutism: Excessive coarse, dark (terminal) hair growth in women, following a male-pattern distribution (face, chest, back, abdomen, etc.)—androgen-driven!
• Hypertrichosis: Excess hair growth not related to androgens or male pattern, affects any gender, any site (not hormone-dependent).

🦠 Causes
• Hirsutism:
 – Polycystic ovary syndrome (PCOS; most common)
 – Idiopathic (often familial, increased follicle sensitivity)
 – Medications (e.g., steroids, certain progestogens, danazol)
 – Ovarian/adrenal tumours, CAH, Cushing’s, menopause
• Hypertrichosis:
 – Genetic syndromes, some drugs (e.g., minoxidil, ciclosporin), metabolic disease, or idiopathic

🧬 Pathophysiology
• Hirsutism = excess androgens or increased follicular sensitivity: vellus → terminal hair in androgen-dependent sites
• Hypertrichosis = NOT androgen-driven; unrelated distribution

📈 Epidemiology
• Hirsutism affects 5–15% of reproductive-aged women in the UK
• PCOS: 5–10% prevalence in this group

🧩 Differential Diagnosis
• Distinguish hirsutism from hypertrichosis
• Rule out: PCOS, adrenal/ovarian tumours, Cushing’s, CAH, medications, familial/genetic syndromes

🩺 Diagnosis
• Detailed history and exam (onset, progression, menstrual & family history, medication)
• Ferriman–Gallwey score: quantifies male-pattern hair
• Bloods: total/free testosterone, FSH/LH, 17-OHP, TFTs, prolactin, cortisol (if indicated)
• Imaging: pelvic US (for PCOS), adrenal/ovarian imaging (if tumour suspected)

⚖️ Management
• Address underlying cause: treat PCOS, tumours, etc.
• Lifestyle: weight loss (esp. PCOS, insulin resistance)
• Cosmetic: shaving, waxing, bleaching, laser (not usually NHS-funded), electrolysis
• Medical:
 – COCP (esp. anti-androgenic types: e.g., co-cyprindiol, drospirenone)
 – Topical eflornithine for facial hair
 – Anti-androgens (e.g., spironolactone—with reliable contraception)
 – Specialist options: GnRH agonists for severe cases, metformin (for PCOS metabolic aspects)

😓 Complications
• Profound psychological impact: low self-esteem, anxiety, depression
• Underlying conditions: untreated PCOS (diabetes, CVD, endometrial cancer risk), tumours (life-threatening if missed), Cushing’s
• Physical: folliculitis, irritation from removal methods

⚕️ FREE MSRA PODCAST – Hereditary Haemorrhagic Telangiectasia (HHT)
🎧 A clear, high-yield breakdown of this genetic vascular condition with bleeding risks – perfect for exam prep and clinical scenarios.

🧠 Key Learning Points

📌 Definition
• A rare, autosomal dominant disorder causing abnormal blood vessel formation – leading to telangiectasia and arteriovenous malformations (AVMs).
• Also known as Osler-Weber-Rendu syndrome.

📌 Causes & Risk Factors
• Inherited mutation in ENG (HHT type 1) or ACVRL1/ALK1 (HHT type 2) genes
• 50% chance of inheritance if one parent is affected
• De novo mutations in ~20% of cases
• No sex or race predominance, but higher prevalence in certain founder populations (e.g. Afro-Caribbean, Curacao)

📌 Pathophysiology
• Defective vessel development → fragile telangiectasia and AVMs
• AVMs bypass capillaries → risk of bleeding or emboli
• Can affect lungs, brain, liver, GI tract

📌 Symptoms
• Recurrent epistaxis (nosebleeds) – often the earliest sign
• Mucocutaneous telangiectasia – blanching red spots on lips, tongue, face, fingers
• GI bleeding → iron deficiency anaemia
• Pulmonary AVMs → breathlessness, hypoxaemia, paradoxical emboli
• Brain AVMs → seizures, headaches, stroke risk
• Liver AVMs → high-output heart failure (rare)

📌 Differential Diagnosis
• CREST syndrome (telangiectasia + scleroderma features)
• Acquired telangiectasia (e.g. sun damage, meds, liver disease)
• Bleeding disorders (e.g. von Willebrand disease)
• Vasculitis (e.g. SLE)

📌 Diagnosis
• Clinical diagnosis via Curacao criteria:
 1. Recurrent epistaxis
 2. Mucocutaneous telangiectasia
 3. Visceral lesions (e.g. AVMs)
 4. First-degree family history
 ✅ 3 = definite HHT, 2 = possible
• Confirm with genetic testing for ENG/ACVRL1 mutations
• Imaging:
 - CT chest / bubble echo → pulmonary AVMs
 - MRI brain → cerebral AVMs
 - GI endoscopy
 - Doppler US/CT/MRI for liver AVMs

📌 Management
• Control bleeding:
 - Iron supplements or IV iron
 - Nasal cautery, laser therapy, septodermoplasty
 - Tranexamic acid for recurrent bleeding
 - Hormonal therapy (e.g. oestrogen) for GI bleeds
• Treat AVMs:
 - Embolisation (lungs, brain)
 - Surgery if required
• Surveillance:
 - Regular screening for AVMs
 - Monitor haemoglobin/iron
• Family screening if mutation confirmed

📌 Complications
• Life-threatening haemorrhage
• Stroke (from paradoxical emboli via lung AVMs)
• Heart failure from hepatic AVMs
• Chronic anaemia, fatigue, poor QoL
• Missed diagnosis due to subtle external signs

📌 Prognosis
• Generally good with early diagnosis, regular screening, and AVM management
• Prognosis depends on location/severity of AVMs
• Genetic counselling and family screening are key for prevention

🎯 Henoch-Schönlein Purpura (HSP) – the most common systemic vasculitis in children – is a high-yield must-know for the MSRA. But don’t be fooled by its familiar rash: this topic hides plenty of traps in both diagnosis and management.

In this focused Deep Dive episode, we break HSP down to its core essentials, linking pathophysiology to presentation, and helping you nail those subtle MSRA vignette clues 🧠

🧬 What You'll Learn:

✅ What HSP actually is – an IgA-mediated small vessel vasculitis
✅ Classic tetrad of features using the mnemonic PAAR:
🔹 P – Purpura (palpable, non-blanching rash)
🔹 A – Arthralgia/arthritis (especially large joints like knees/ankles)
🔹 A – Abdominal pain (colicky, +/- GI bleeding)
🔹 R – Renal involvement (haematuria, proteinuria)

✅ High-yield triggers: preceding infections (especially strep), drugs, vaccines
✅ Differentials you must exclude:
🚨 Meningococcal sepsis – purpura + unwell child = emergency
⚠️ Intussusception – GI pain + red currant jelly stool

✅ The role of IgA immune complexes and how they damage vessel walls
✅ Why urinalysis is the most important investigation 🔍
✅ When and why to consider steroids
✅ The MSRA trap: When to avoid NSAIDs
✅ Why adults have worse outcomes – especially kidneys
✅ Prognosis pearls and how to approach long-term monitoring for CKD

🧠 MSRA Nuggets & Exam Tips:

💡 Don’t forget to ask about infection history – a cold 1–3 weeks ago is a classic clue
💡 Purpura + tummy pain ≠ always HSP – rule out sepsis and intussusception first
💡 Palpable purpura + normal platelets? → Think HSP (vs. ITP which has low platelets)
💡 Use PAAR to guide diagnosis and follow-up
💡 Long-term urine dip follow-up is vital – even if initial symptoms resolve

⚕️ FREE MSRA PODCAST – Guttate Psoriasis
🎧 A clear, high-yield breakdown of this immune-mediated skin condition triggered by strep – perfect for exam prep and real-life diagnosis.

🧠 Key Learning Points

📌 Definition
Guttate psoriasis is an acute form of psoriasis characterised by small, drop-shaped red scaly lesions, often appearing after a streptococcal throat infection.

📌 Causes & Risk Factors
• Recent streptococcal throat infection (typically 2–4 weeks prior)
• Younger age group – commonly children, teens, young adults
• Genetic predisposition – family history of psoriasis
• Triggers: stress, skin injury (Koebner phenomenon), medications
• Drugs: antimalarials, lithium, NSAIDs, beta blockers
🧠 Mnemonic: “STREP DROP” – Strep infection, Teens, Rashes, Erupt Post-infection

📌 Pathophysiology
• Immune overactivation → rapid skin cell proliferation
• Skin cells build up too fast → red, scaly papules
• Triggered by streptococcal antigens activating T cells in genetically susceptible individuals

📌 Symptoms
• Sudden eruption of 1–10 mm red, scaly papules
• Often mildly itchy
• Distribution: trunk, proximal limbs, scalp
• Palms/soles rarely involved
• Nail changes usually absent – key distinction from plaque psoriasis

📌 Differential Diagnosis
• Plaque psoriasis
• Pityriasis rosea (look for herald patch)
• Tinea corporis
• Nummular eczema
• Drug eruption
• Viral exanthems
• Secondary syphilis
• Lichen planus
• Cutaneous T-cell lymphoma
• Pityriasis lichenoides

📌 Diagnosis
• Clinical – based on history (esp. recent sore throat) + lesion appearance
• Consider ASO titre or throat swab to support strep link
• Dermoscopy if needed to differentiate
• Skin biopsy only in atypical/unclear cases

📌 Management
• Reassure: most cases resolve in 2–3 months
• Topicals: corticosteroids, emollients, vitamin D analogues
• Phototherapy (UVB) for widespread/resistant cases
• Antibiotics only if active streptococcal infection is present
• Tonsillectomy may be considered for recurrent strep-linked flares
❗ Critical Exam Point: Antibiotics DO NOT treat the skin lesions

📌 Complications
• Progression to chronic plaque psoriasis
• Recurrent episodes – especially after infections
• Post-inflammatory pigmentation (hypo/hyper)
• Rare: pustular or erythrodermic psoriasis (emergencies)
• Iatrogenic issues from steroids/phototherapy (skin thinning, telangiectasia, etc.)

📌 Prognosis
• Excellent in many cases – complete resolution is common
• Younger patients and high ASO titres = better prognosis
• Monitor for chronic progression in some individuals

✅ MSRA Deep Dive: Granuloma Annulare – A Benign Mystery with Clinical Clues
In today’s episode, we unpack granuloma annulare – a deceptively simple skin condition that crops up in exams and clinics alike. Based on high-yield revision content, we explore the types, differentials, and management, and connect this apparently harmless condition to broader systemic associations you can’t afford to miss in the MSRA.

🧠 Key Learning Points

📌 Definition
• Granuloma annulare is a benign, chronic skin condition
• Presents with smooth, raised, ring-shaped lesions
• Typically affects hands, feet, elbows, and knees

📌 Causes & Risk Factors
• Cause: Unknown – exact trigger not clearly established
• Suggested links to:

• Trauma or minor injury

• Systemic illnesses like diabetes mellitus and thyroid disease

• Infections or certain medications

• Immune dysregulation, possibly TNF-alpha mediated
  • More common in children and young adults, with localized type seen most frequently in under-30s

📌 Pathophysiology
• Thought to be an immune response to an unknown antigen
• Infiltration by macrophages forms granulomatous nodules in a ring-like (annular) pattern
• Different forms include:

• Localized (most common)

• Generalized

• Subcutaneous

• Perforating

📌 Clinical Features by Type

1. Localized – few ring-shaped, asymptomatic, smooth lesions, often on extremities

2. Generalized – widespread annular plaques, seen more in adults, may coalesce

3. Subcutaneous – deep lumps, often on shins, typically in children

4. Perforating – ulcerated, symptomatic, seen in young adults or elderly, may scar

📌 Differential Diagnoses
• Lichen planus
• Sarcoidosis
• Rheumatoid nodules
• Tinea corporis (ringworm)
• Pityriasis rosea
• Nummular eczema
• Psoriasis
• Erythema chronicum migrans (Lyme disease)
• Leprosy
🟢 Key differentiator: Smooth, non-scaly surface, unlike eczema/psoriasis

📌 Diagnosis
• Primarily clinical – based on appearance and history
• Skin biopsy if:

• Atypical appearance

• Concern for other diagnoses
  • Blood tests only if signs point to systemic disease (e.g., diabetes, thyroid issues)

📌 Management

1. Localized GA

   • Often needs no treatment – self-limiting within ~2 years

   • If symptomatic or cosmetically concerning →
     • Topical corticosteroids
     • Intralesional steroids
     • Cryotherapy or laser therapy

2. Generalized GA

   • Requires systemic treatment in many cases

   • Options include:
     • PUVA (phototherapy)
     • Methotrexate, cyclosporine, dapsone, antimalarials
     • TNF inhibitors for resistant disease
     • Oral steroids for short-term relief
     • Isotretinoin (occasionally used)

3. Subcutaneous GA

   • Often managed with reassurance

   • Surgical excision considered in persistent, bothersome lesions

4. Perforating GA

   • Hardest to treat

   • May ulcerate and leave pigment changes or scarring

📌 Prognosis
• Localized type: Excellent – resolves in most within 2 years
• Generalized: May persist up to 10 years, often recurrent
• Subcutaneous/perforating: Variable, but may recur or scar
🟢 Key Point: Condition is benign, but chronicity and visibility can impact mental well-being

📌 Complications
• Scarring or pigmentary changes (especially perforating type)
• Emotional distress – visible skin lesions can affect self-esteem and quality of life
• Possible clue to underlying systemic conditions (e.g., diabetes, thyroid dysfunction)

⚕️ FREE MSRA PODCAST – Fungal Nail Infections (Onychomycosis) Demystified
🦶 Your high-yield, no-fluff guide to diagnosing and managing onychomycosis in UK clinical practice and for MSRA revision!

🧠 Key Learning Points

📌 Definition
• Fungal infection of the nail unit (mostly toenails), causing thickening, discolouration (yellow, brown, white), brittleness, and possible pain.

📌 Causes & Risk Factors
• Dermatophytes (esp. Trichophyton rubrum), yeasts (Candida), non-dermatophyte moulds
• Key risk factors: Older age, Lifestyle (sports, communal bathing), Diabetes, Trauma, Immunocompromised, Moist environments, Existing skin infection (tinea pedis), Shared items (mnemonic: OLD TIMES)

📌 Pathophysiology
• Fungus invades the nail plate via cracks/skin, multiplies under nail, causing classic nail changes
• Commonest subtype: Distal and lateral subungual
• Others: Superficial white, proximal subungual, total dystrophic

📌 Clinical Features
• Discoloured, thick, crumbly nails
• May lift from nail bed (onycholysis)
• Not always painful, but can impair function and confidence

📌 Differential Diagnoses
• Psoriasis (esp. with skin plaques), lichen planus, trauma, eczema, bacterial infections (e.g. Pseudomonas – green), subungual melanoma (don’t miss!), yellow nail syndrome, thyroid disease

📌 Diagnosis
• Confirm by lab: Nail clippings/scrapings for microscopy, culture (PCR sometimes used)
• Dermatophyte: Either microscopy OR culture +ve
• Candida: BOTH microscopy AND culture +ve
• Non-dermatophyte moulds: BOTH +ve, ideally 2 samples
• Sample from deepest part of affected nail

📌 Management
• Only treat if functionally/cosmetically troublesome
• First line: Oral terbinafine (fingers: 6 weeks–3 months; toes: 3–6 months)
• Alternatives: Oral itraconazole (esp. for Candida), topical lacquers for mild/SWO
• Self-care: Good foot hygiene, keep nails trimmed, treat tinea pedis, avoid shared nail tools, breathable shoes
• Refer if: diagnosis unclear, fails treatment, needs surgery, immunosuppressed, extensive/recurrent cases

📌 Complications
• Permanent nail damage/loss, secondary bacterial infection (risk of cellulitis/osteomyelitis in diabetics/elderly), pain, psychosocial impact

📌 Prognosis
• Many cases can be cured, but success not 100%; nail takes months to regrow
• Prevention: hygiene, treat athlete’s foot, avoid trauma

🎙️ MSRA Deep Dive: Erythema Nodosum Explained 🩺🔥

Ready for a high-yield session that simplifies Erythema Nodosum (EN) for your MSRA prep? In this episode, we unravel the must-know facts, clinical patterns, and killer differentials that will help you ace any exam question on this deceptively simple-looking skin condition. Let’s get straight to the essentials and stick them in your long-term memory. 🧠📚

🔍 Key Learning Points:

✅ Definition:
Erythema Nodosum is an inflammatory condition affecting the subcutaneous fat (panniculitis), commonly presenting as painful red nodules on the shins. It’s often a reaction pattern to an underlying systemic issue rather than a standalone disease.

✅ Causes (📌Think "SO STIR PIM"):
• Strep infections (especially after sore throat)
• OCP (Oral Contraceptive Pill)
• Sarcoidosis
• Tuberculosis
• Inflammatory Bowel Disease (Crohn’s/UC)
• Respiratory infections
• Pregnancy
• Idiopathic (often the case)
• Medications (penicillin, sulfonamides)

✅ Symptoms:
• Tender, symmetrical, red nodules, mostly on the anterior shins
• May have systemic features like malaise, fever, joint pain (arthralgia)
• Nodules evolve like bruises: red → purple → brownish-yellow
• Joint pain often affects ankles, knees, wrists – but with no joint destruction

✅ Investigations:
🎯 To find the trigger, not just confirm the diagnosis:
• ASO titre, throat swab (for strep)
• CXR, serum ACE, calcium (for sarcoidosis)
• ESR/CRP, FBC
• TB tests (Mantoux, IGRA)
• Consider stool studies, blood cultures, or autoimmune screening
• Skin biopsy if atypical features are present (e.g. ulceration)

✅ Red Flags / Differentials:
🚨 If the nodules ulcerate or appear on non-leg sites – rethink your diagnosis!
• Erythema induratum
• Vasculitis
• Cellulitis
• Rheumatoid nodules
• Thrombophlebitis
• Sarcoidosis-associated nodules

✅ Management:
• Usually self-limiting (resolves in 6–8 weeks)
• NSAIDs, cool compresses, leg elevation
• Colchicine can help with inflammation
• Treat the underlying cause (e.g. antibiotics for strep, IBD management)
• Avoid steroids unless infection is ruled out – they can worsen hidden infections like TB

✅ Prognosis:
• Excellent in most cases
• Chronic/recurrent EN is rare
• Nodules heal without scarring
• Important to find and treat any underlying chronic or systemic condition

🎯 Deep Dive: Erythema Multiforme (EM) for the MSRA
Welcome to another high-yield episode of the Deep Dive podcast — your ultimate companion for MSRA revision! Today, we’re zooming in on a condition that sounds serious, looks striking, and often causes confusion: Erythema Multiforme (EM). Let’s break it down together and separate it clearly from its dangerous cousins, SJS and TEN. 🎯🧠

🔍 What You’ll Learn (And Remember!)
✅ Definition: EM is an acute, immune-mediated skin condition known for its classic target lesions
✅ Not SJS/TEN: Know the key differences — EM is usually self-limiting, while SJS/TEN are medical emergencies
✅ Common Triggers:
• 🦠 HSV (Herpes Simplex Virus) – most common
• 💊 Drugs – e.g., penicillin, sulfonamides, carbamazepine
✅ Risk Factors: Prior HSV infections, recent drug use, autoimmune conditions
✅ Pathophysiology: CD8+ T cells mistakenly attack skin → inflammation & lesions
✅ Classic Clinical Clues:
• 🎯 Target lesions with 3 zones (central blister or bump, pale ring, outer violaceous halo)
• 😬 Painful mouth ulcers in some cases
• 👋 Often starts on hands/feet → spreads centrally
✅ Investigations:
• 📋 Diagnosis is clinical
• 🧪 Tests only if atypical or recurrent → e.g. viral PCR, skin biopsy
✅ Management Plan:
• ❌ Stop culprit drug if identified
• 🧼 Supportive care – emollients, analgesia, antiseptic mouthwash
• 💊 Consider antivirals for recurrent HSV-triggered EM
✅ Prognosis: Good! Most cases resolve in weeks
✅ Complications:
• 🦠 Secondary infection
• 👁 Eye complications
• 🧪 Rare progression to SJS/TEN – must distinguish early!

• EM = acute hypersensitivity → target lesions
• HSV most common trigger
• Don’t confuse with SJS/TEN
• Management = supportive + remove trigger
• Think HSV suppression if recurrent
