Angiokeratoma of the Glans Penis.

Angiokeratoma of the Glans Penis. Skinmed. 2017;15(5):343-347 Authors: Beutler BD, Cohen PR Abstract Angiokeratomas are benign vascular lesions characterized by ectatic blood vessels in the papillary dermis with overlying acanthosis and hyperkeratosis, often occurring as idiopathic scrotal tumor and rarely as penile lesions. Twelve men, including our case of a 58-year-old white man, have been reported with angiokeratomas of the glans penis. The lesions typically present as asymptomatic dome-shaped papules ranging in size from 0.5 to 5 mm and present as red, purple, blue, or black lesions along the penile coronal rim. Histopathologic examination of the lesions reveals dilated, thin-walled vascular structures in the upper portion of the dermis with overlying acanthosis and/or hyperkeratosis. Such angiokeratomas may have a multifactorial etiology with elevations in local venous pressure, degeneration of elastic tissue, and/or capillary injury. Biopsy would exclude a melanocytic lesion, particularly melanoma. Laser surgery is an option for patients presenting with multiple lesions or lesions that coalesce to form a plaque.
