A 70-year-old man comes to the office because he is concerned about purplish scrotal lesions. These are asymptomatic and “possibly present for several years.” His medical history is positive for hypertension, for which he currently takes hydrochlorothiazide. On physical examination, scattered violaceous papules, each measuring about 1 mm in diameter, are scattered on the scrotum, which has a reddish tinge. No similar lesions are noted elsewhere.

Angiokeratoma of Fordyce presents with small hemangiomas, ranging from 1 to 2 mm in diameter. The papules are red or purple and may be associated with generalized scrotal redness.1 Angiokeratoma of Fordyce often presents in the second or third decade...

Angiokeratoma of Fordyce presents with small hemangiomas, ranging from 1 to 2 mm in diameter. The papules are red or purple and may be associated with generalized scrotal redness.1 Angiokeratoma of Fordyce often presents in the second or third decade of life but is most common in older men.2

The lesions are believed to be triggered by elevated venous pressure. Scrotal angiomas may be associated with an inguinal hernia, varicose veins of the leg, or a varicocele.3

No treatment is necessary, and patients should be reassured that the hemangiomas are benign. If desired, shave excision, cautery, laser ablation, or fulguration can be performed to remove the lesions.4
