Extramammary Paget's disease of the scrotum.

Extramammary Paget's disease is an uncommon intra-epidermal malignant neoplasm that arises in area rich in apocrine glands. Common sites of occurrence include the vulva, perianal region, perineum, and scrotum. The lesion may be accompanied by an invasive adenocarcinoma or adenocarcinoma in situ of the apocrine glands. Generally, the prognosis is poor. Herein, we report two cases of extramammary Paget's disease, one involving the penoscrotal area with bilateral inguinal and pelvic lymph node metastases, the other involving the scrotal area without metastases.
