Acquired progressive lymphangioma in the inguinal area mimicking giant condyloma acuminatum

Lymphangioma is a benign proliferation of the lymphatic vessels that accounts for approximately 4% of vascular malformations and 26% of benign vascular tumors. Compared to those arising in nongenital areas, lymphangiomas of the vulva and genital areas are more hyperplastic, possibly due to the loose connective tissue, which can cause a cauliflowerlike appearance and may easily be misdiagnosed as genital warts or molluscum contagiosum. We report a case of acquired progressive lymphangioma (APL) of the inguinal area that mimicked giant condyloma acuminatum and showed favorable results following surgical excision. We also provide a review of the literature regarding the pathogenesis, diagnosis, differential diagnosis, and treatment of APL.
