[Malignant mesothelioma of the vulva. About one case]

Most malignant mesotheliomas are pleural; they rarely occur within the peritoneum and their location in the vulva is exceptional. A case of a malignant mesothelioma of the vulva is reported in a 47-year-old woman. The patient was operated for a tumour of the vulva. The preoperative diagnosis was that of a cyst of the Bartholin's gland or a fibroma. The microscopic and immunohistochemical exam confirmed the diagnosis of a biphasic malignant mesothelioma of the vulva. The computed tomography scan of the chest and the abdomen was normal. A local recurrence of the tumour occurred in spite of the postoperative radiotherapy. Our objective about this particular case is to discuss the clinical and pathologic aspects and the diagnostic problems of this exceptional tumour of the vulva.
