APOCRINE HIDROCYSTOMA OF THE EYELID: A RARE CASE REPORT

Introduction: Apocrine hidrocystomas are rare, benign cystic tumors arising from apocrine sweat glands, commonly found in the head and neck region. They may present in the periorbital area, including eyelids, canthi, and eyebrows. Although benign, histopathological confirmation is essential to rule out malignancy.

Case Report: A 20 year-old male presented with a one-month history of swelling below the left medial canthus. Examination revealed a solitary, firm, dome-shaped, translucent, mobile nodule measuring 2 1 cm on the left lower eyelid. CT orbit showed a well-defined 1.3 1.2 cm hypodense lesion (25 HU) in the inferomedial extraconal space, abutting the medial rectus. Surgical excision was performed. Histopathological analysis showed fibrocollagenous tissue lined by flattened to cuboidal epithelium, confirming apocrine hidrocystoma.

Conclusion: Apocrine hidrocystomas carry an excellent prognosis with surgical excision. Histological evaluation is crucial to exclude malignancy and ensure accurate diagnosis and treatment.
