Abstract

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare low-grade sweat gland carcinoma with a strong predilection to the eyelid region. It is histologically analogous to endocrine ductal carcinoma/solid papillary carcinoma of the breast and is characterized by a multinodular solid cystic mucinous tumor with immunoreactivity to neuroendocrine markers. Only 20 cases of this unusual tumor have been reported. We present the clinical and histopathologic findings of 2 new cases of EMPSGC and review the relevant literature. The histological differential diagnosis is discussed and attention drawn to the role of immunohistochemistry in clarifying the nosological position of EMPSGC within the spectrum of cutaneous mucinous neoplasms.
