Abstract

We report a case of basal cell carcinoma (BCC) in the area of the genital Paget's disease. A 85-year-old woman noticed erythema on her vulvar region 3 years before, and the erythema gradually increased in size and followed erosion and ulcus on the erythema. Histologically, erythema revealed Paget's disease and the ulcus was the solid type of BCC.
In the bordered area of Paget's disease and BCC, Paget cells infiltrated into the mass of BCC in the dermis, which were demonstrated with an immunopathological method using anti-CEA antibody.
We speculated that the genital Paget's disease and BCC developed isolatedly in the different places nearly, after that, the BCC was surrounded by Paget's disese.
