Abstract
Purpose
Eccrine ductal carcinoma is an extremely rare tumor that arises in the eccrine sweat glands. The authors of the present study describe a case of an eyelid mass diagnosed as eccrine ductal carcinoma.
Case summary
A 74-year-old woman visited our institute with a 3-month history of a mass in the left medial canthus. The lesion appeared as a solitary nodule with central ulceration. A magnetic resonance imaging (MRI) of the orbit showed a relatively well enhanced 0.8 cm × 0.8 cm-sized ovoid soft tissue mass. A mass excision was performed under frozen section control. The tumor was completely excised with margin clearance and medial canthal reconstruction was performed. Histopathological examination revealed a tumor composed of numerous duct-like structures lined with pleomorphic cuboidal epithelium that was diagnosed as eccrine ductal carcinoma of the eyelid.
