Lymphangioma circumscriptum of the penis mimicking venereal lesions.

Lymphangioma circumscriptum (LC) involving the penis is rare. We report two patients with penile LC. The lesions developed in early infancy in one patient, and during puberty in the other. The lesions resembled molluscum contagiosum in one and genital warts in the other. The first patient was previously treated with a diagnosis of venereal disease. A literature search found only 4 LC patients with penile lesions reported in the English literature. These cases are presented for their rarity, and to increase diagnostic vigilance and desirability of non-intervention.
