We report a case of lymphangioma of the penis. A 45-year-old man presented with a painless mass on the dorsal penis. A soft and movable mass was excised under local anesthesia. Pathological findings demonstrated vast amounts of fluid, which did not involve any blood cells and confirmed it to be cavernous lymphangioma. After 2 years postoperatively, no evidence of recurrence was present. We review 22 reports of penile lymphangioma in Japan.
