A case of squamous cell carcinoma of the scrotum associated with invasion of surrounding dermal lymphatic vessels and regional lymph node metastasis.

A-75-year-old man developed a rapidly growing tumor followed by swelling of regional lymph nodes, on the left side of his scrotum. Histopathological examination of the tumor revealed a deep invasion of atypical squamous cells associated with embolism of dermal lymphatic vessels by tumor cells, as far as 4cm apart from the tumor. Wide local excision of the tumor including total scrotal skin and bilateral ilioinguinal lymph node dissection was performed. Subsequently five courses of chemotherapy with cisplatin and fluorouracil and radiotherapy were added. In spite of these treatments, he had a recurrence located on the posterior border of the grafted skin of scrotum one year after the operation. [Skin Cancer (Japan) 2001; 16: 47-50]
