Apocrine Hidrocystoma: A Rare Case Report
- 45 Downloads
Hidrocystoma is a cystic tumor originating from a dilated sweat gland. The tumor is typically small and located predominantly on the face, particularly in the eyelid margins. They are two classical types of hidrocystomas i.e., Apocrine and Eccrine. Apocrine hidrocystomas are cystic lesions that arise from the apocrine secretory coil and Eccrine hidrocystomas represent retention cysts of the eccrine duct. Multiple apocrine hidrocystomas confined to the eyelids have been recognized as a feature of a new variant of ectodermal dysplasia. Here we present a rare case of Apocrine hidrocystoma of supraorbital area for which excisional biopsy of the lesion was performed. Histopathological evaluation proved the lesion was a unilocular cyst lined by a double-layered epithelium of the apocrine type. The purpose of this paper is to report the unique occurrence of a Supra orbital apocrine hidrocystoma which was clinically as a sebaceous cyst and to discuss its differential diagnosis with other more common supraorbital and face lesions.
