A case of acquired lymphangioma of the vulva.

A 46-year-old woman developed multiple papules on the right labium majus. A histological examination revealed acanthotic epidermis and dilated vessels in the papillary dermis. The clinical and histological features were compatible with those of lymphangiectasis or acquired lymphangioma of the vulva, which occurs after surgery or irradiation for cervical cancer. This patient, however, had no such past history. Acquired lymphangioma of the vulva arising without obvious causes seems to be unusual.
