A Case of Nodular Hidradenoma of Upper Eyelid Presenting with Ptosis

ABSTRACT

PURPOSE: To report the presentation and management of an atypical and advanced case of nodular hidradenoma of the eyelid with ptosis. CASE SUMMARY: A 64-year-old woman who presented with a palpable growing nodular mass and ptosis was tested with marginal reflex distance 1 as right eye 1 mm, left eye -1.5 mm and levator function test as 12 mm and 10 mm, respectively during a hospital visit. The patient was tentatively diagnosed with eyelid adnexal tumor with mechanical ptosis and was managed by surgical excision of the lesion. Histology confirmed hidradenoma. CONCLUSIONS: Hidradenomas are benign adnexal tumors originating from the eccrine gland and rarely detectable in the eyelid. However, rudimentary glandular structures can be a possible tumor source. Nodular hidradenoma should be considered in the differential diagnosis of adnexal masses and such lesions may cause significant functional and cosmetic morbidity despite their histologically benign nature.
