Treatment of invasive squamous cell carcinoma complicating anal Buschke-Löwenstein tumor: a case history.

We present here the case of a patient with Buschke-Löwenstein tumor of the anus complicated by invasive squamous cell carcinoma metastatic to the inguinal and periaortic pelvic lymph nodes. Successful local palliation was achieved with 5-fluorouracil and mitomycin-C-based chemotherapy combined with radiation therapy, but systemic progression was unaffected.
