Clinical Analysis of 36 Cases of Sweat Gland Carcinoma

Abstract

Thirty-six cases of sweat gland carcinoma excluding extramammary Paget's disease were clinically analyzed. The patients were diagnosed and treated in our department from 1996 to 2015. They included 18 males and 18 females with an average age of 68 years (range 29-91 years). The primary lesion was located in the trunk in 15 patients, the foot in 7 patients, the lower extremities in 6 patients, and other places in 8 patients. Lymphnode metastasis was observed in 15 patients and distant metastasis in 9 patients, all of whom died of the disease.

Because of the rarity and the histological diversity in malignant sweat gland tumors, there is no established histological classification nor standard treatment. A prospective multicenter study is warranted.
