Case Study for TWiP 165

Still in Uganda. Young boy came from a distance to see Daniel, teenager with large swelling in scrotum, left side, 4-6 cm diameter, superior to testicle. Not only young man in area with similar problem. Daniel asked, are there people with large swollen legs? He said yes, my brothers wife, left leg is large, swollen, irregularity. Nontender. Can be transilluminated, and it glows.
