Syringomas are small, harmless, asymptomatic, flesh-to-yellow-colored bumps that are thought to arise from eccrine sweat ducts. Although they are often seen in clusters on the eyelids and upper cheeks, they can also occur on the neck, upper chest, armpits, umbilicus, vulva and less frequently on the penis. Syringoma on the penis can be quite distressing and worrisome for most individuals. People often fear the lesion for being sexually transmitted such as condyloma accuminata, so the cosmetic appearance of the lesion can be of major concern to individuals and their partners affecting their sexual life too.
They usually appear as multiple asymptomatic smooth, rounded or dome shapes bumps on the shaft of penis in young individuals often less than 30 years. Color range from yellow-white papules to skin color bumps and sometimes brownish-red color bumps. They are often few millimeters in size to almost 10 mm.
As syringoma of the penis is uncommon, so in such atypical localization, it is always necessary to exclude other similar condition that can have similar presentation as syringoma. When there is confusion your dermatologist may perform the biopsy. As syringoma have distinct histopathological features, it can be easily confirmed with a punch skin biopsy and the patient’s fears about sexually transmitted disease or cancer can be easily excluded.

Treatment of Penile Syringoma
As syringomas are harmless so treatment is not necessary. For a cosmetic reasons it can be removed by surgical excision, cryotherapy with liquid nitrogen, electrodessication and curettage. Carbon-dioxide laser may give more successive results. With all these treatment options available, syringoma can still recur frequently and the risk of scarring is a major problem. So there is no any successful syringoma removal procedure.
