Cutaneous vulvar metastases in a patient with anal squamous cell carcinoma.

Metastatic disease of the skin can be difficult to diagnose, particularly when lesions occur in unusual anatomic locations. We report the case of an 80-year-old woman with a history of anal squamous cell carcinoma (SCC) who developed genital ulcers. Biopsy of the lesions revealed features consistent with metastatic SCC. Cutaneous metastases are an infrequent cause of genital ulcerations, and it is important for physicians to consider this entity when evaluating genital ulcers in patients with prior malignancies.
