Mixed tumor of the vulva: a report of two cases probably arising in Bartholin's gland.

A case of benign mixed tumor of the vulva and a case of carcinoma arising in a similar benign mixed tumor of the vulva are reported. Both mixed tumors were of salivary gland type and probably arose in the Bartholin's gland. Only three previous cases of benign mixed tumor of the vulva have been documented in the literature. Two arose in the vestibular glands, and the third arose in cutaneous sweat glands. No case of carcinoma arising in a benign mixed tumor of the vulva has been previously documented.
