Most authors regard lymphangiomas as malformations that arise from sequestrations of lymphatic tissue that should communicate normally with the lymphatic system. The majority of lymphangiomas seem developmental lesions occurring relatively early in life, but it rarely present in adult life. We report the case of a 17-year-old female with clitorial mass. Histological features that favor the diagnosis of lymphangioma over hemangioma are the presence of lymphoid aggregates in the stroma and more irregular lumina with widely spaced nuclei. The therapy of choice is a complete surgical excision. Our patient was excised her lesion completely and resulted in good prognosis.
