Masquerading eyelid mass: An unusual case of eccrine poroma

Eccrine poroma is a benign adnexal tumor that usually arises on acral skin, particularly the palms and soles, from the intraepidermal portion of eccrine sweat ducts. Its occurrence on the eyelid is exceedingly rare and may mimic more common eyelid lesions, making clinical diagnosis difficult. We report the case of a 41-year-old woman with a painless, slowly enlarging nodule of the left upper eyelid, developing over 7 years following trauma. A provisional diagnosis of epidermal inclusion cyst was made. Surgical excision was performed, and histopathology confirmed eccrine poroma. This case highlights the importance of considering eccrine poroma in the differential diagnosis of chronic eyelid masses, especially at atypical sites, and reinforces the role of histopathology in achieving a definitive diagnosis.
