Abstract
We studied 39 cases of genital Paget’s disease treated at the dermatological department of Chiba University Hospital, especially in view of this disease’s therapeutic plan. The invasion depth of the primary lesions divided the 39 cases into 4 types, superficial, comedo carcinoma, lesions invading the dermal papillary layer and those lesions invading deeper than the dermal reticular layer. Each of above was composed of 10, 11, 7 and 11 cases. Nine of the 11 cases with deep invading type had metastasis to the regional lymph nodes. The cases with metastatic lymph nodes had induration, and either a tumor or ulceration in the primary lesion. The size of the primary lesion, duration from occurence to therapy or clinical lymph node swelling did not always help in accurately detecting metastasis.
