A hemangioma is a benign vascular neoplasm that may be present at birth or that may arise later in life. Hemangiomas in the anogenital area represent a heterogeneous group. They may be found on the glans penis, shaft, or scrotum. Ulceration may occur. Normally the lesions are asymptomatic, but in adulthood, bleeding may occur after intercourse. If scrotal hemangiomas grow large enough, they can cause azoospermia due to the increased heat they bring to the testicles.

• Infantile hemangiomas are usually noticed at approximately 2-3 weeks of life.
• Cavernous hemangiomas are deeper tumors. While they may represent deep infantile hemangiomas, some reported cavernous hemangiomas represent venous malformations rather than true neoplasms. They may arise within the testes or within the scrotum.
• Lobular capillary hemangiomas (pyogenic granulomas) are acquired hemangiomas that usually present later in adulthood.
