Utility of Insulinoma-Associated Protein 1 (INSM1) and Mucin 2 (MUC2) Immunohistochemistry in the Distinction of Endocrine Mucin-Producing Sweat Gland Carcinoma From Morphologic Mimics.

Am J Dermatopathol 2022 Feb;44(2):92-97

Department of Pathology, Brigham and Women's Hospital and Harvard Medical School, Boston, MA.

Abstract: Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare low-grade adnexal malignancy with a predilection for the eyelids of elderly White women, which is associated with invasive mucinous carcinoma with endocrine features in one-third of cases. EMPSGC is characterized by the presence of neuroendocrine differentiation and mucin production. However, EMPSGC displays a variety of architectural patterns including solid, cribriform, papillary, and cystic growth. Read More

Apocrine hidrocystoma: a slowly growing postauricular translucent nodule.

Dermatol Online J 2021 01 15;27(1). Epub 2021 Jan 15.

Epiphany Dermatology, Dallas, TX,

Apocrine hidrocystoma is a benign, cystic proliferation of the apocrine sweat gland that may present commonly on sun-exposed areas of the head and neck. However, given its location and features, apocrine hidrocystomas may often be confused with malignant tumors such as basal cell carcinomas or primary cutaneous mucinous carcinomas. Herein, we present an unusual case of an apocrine hidrocystoma presenting in the postauricular region and highlight the importance of histopathological examination of cystic tumors on the periauricular area.
