Metastatic sweat gland carcinoma

In summary the diagnosis of malignant non-metastasizing sweat gland carcinoma is difficult. In cases of metastasizing malignant sweat gland carcinomas, one must distinguish this lesion from metastastic breast carcinomas. The regional lymph nodes are the most likely site of metastasis in sweat gland carcinomas. Wide excision of the primary tumor with resection of the involved regional lymph nodes is considered to be the best initial treatment. Cure rates are in general poor, based on the small number of cases and inadequate follow-up.
