[Vulvar invasive squamous cell carcinoma and hidradenoma papilliferum. Case report]

We report a case of a vulvar invasive squamous cell carcinoma associated to a benign tumor with apocrine differenciation, the hidradenoma papilliferum, infiltrated by the carcinoma. Diagnosis was established by clinical and histopathological examination, first on biopsy and then on local vulvar excision. Classical association between hidradenoma papilliferum and Paget's disease is described, but to the best of our knowledge, there have been no previous reports of such case in published literature. A common physiopathological etiology cannot be completely excluded.
