Sweat gland carcinoma: a clinico-pathological reappraisal.

A case of sweat gland carcinoma arising from the right fifth finger which later metastasized to the regional lymph nodes and the lungs is the subject of this report which attempts to establish further the true characteristics of this definite pathological entity. The diagnosis of sweat gland carcinoma has been loosely applied to a variety of lesions, and it was not until recently that more exact and appropriate criteria were used to establish the diagnosis of sweat gland carcinoma. The case reported in this manuscript possesses most if not all the criteria necessary to make a diagnosis of sweat gland carcinoma. Further review of the literature shows that this is a rare and aggressive neoplasm as this case illustrates. Radical surgery of the primary lesions with radical regional lymph node dissection whenever possible is recommended for the initial treatment, and combination chemotherapy and radiotherapy may be employed in the palliative treatment of the more advanced forms of the disease.
