Mucinous eccrine adenocarcinoma of the eyelid: report of 6 cases.

Objective: To report on patients with mucinous eccrine adenocarcinoma of the eyelid.
Design: Retrospective case series.
Participants: Biopsy specimens of 6 patients with eyelid neoplasm were obtained. The pathologic diagnoses were mucinous eccrine adenocarcinomas.
Methods: The medical records, including demographic, clinical, histopathologic, and follow-up information, were reviewed.
Results: Five patients underwent surgical removal of the lesion by means of Mohs micrographic surgery. Four of these patients were doing well; 1 of them, with positive margins of resection, had 2 recurrences. One case was lost to follow-up.
Conclusions: Mucinous eccrine adenocarcinoma is an uncommon adnexal tumour that can involve the eyelid, has low metastasis and mortality, but can be invasive or locally recur. Mohs micrographic surgery is a recommended treatment of mucinous eccrine adenocarcinoma of the eyelid.
