[Transition to cutaneous squamous cell carcinoma in 2 patients with bowenoid papulomatosis].
We report on two female patients (30 and 33-year-old) suffering from bowenoid papulosis (BP) which showed HPV-16-DNA (E.-M. de Villiers, DKFZ, Heidelberg). Both patients developed cutaneous invasive squamous cell carcinoma in the perineal and vulvar region, resp. In the first patient, the microinvasive part of the tumor was excised. Subsequent therapy with interferon-gamma resulted in complete clinical and histological remission of the BP within 4 months; 6 months after discontinuation of the therapy with interferon, however, we observed a relapse of BP. In the second case, which showed more prominent BP alterations and deeper tumor invasion, interferon-gamma did not bring on any improvement within 3 weeks of therapy; thus radical operation was performed. To our knowledge, this is the first report on the transition of BP of the outer ano-genital region into invasive squamous cell carcinoma.
