Generalized malignant acanthosis nigricans.

We report a case of generalized malignant acanthosis nigricans (AN) secondary to metastasizing squamous cell carcinoma of the cervix uteri. The disease initially manifested in the perineum as condyloma acuminatum-like lesions. Subsequently, most of the cutaneous surface and the mucosa of the vulva, mouth, tongue, and the palpebral conjunctiva became involved. The association of AN with a squamous cell carcinoma is rare, and conjunctival involvement is unusual.
