Primary Mucinous Eccrine Adenocarcinoma – A Rare Malignant Cutaneous Adnexal Neoplasm at an Unconventional Site

Primary Cutaneous Mucinous Carcinoma of the Eyelid: A Case Report

“…Primary cutaneous mucinous carcinoma is a rare adenocarcinoma of the skin for which there is controversy regarding whether it arises from the eccrine sweat gland or the apocrine gland [1,2,4]. There is difficulty in distinguishing this primary neoplasm from metastatic mucinous carcinoma of non-cutaneous origin with primary sites in the lungs, breast, colon, and ovaries [5,6]. These tumors have a higher male predominance and occur more frequently in the elderly [1,3,7].…”

“…In the literature, the recurrence rate is attributed to incomplete excision of the tumor. For recurrent cases and sites such as the eyelid, Moh's micrographic surgery is preferred as this allows for the complete removal of the tumor along with margins and preserves tissue, bronchi, renal pelvis, and ovary (6). It is also important to differentiate metastatic mucinous adenocarcinoma (1,3,8); this can be done via a thorough clinical and imaging assessment (4).…”
