Bilateral Apocrine Hidrocystomas in the Lower Conjunctival Fornix: A Case Report

We report the case of an elderly patient who presented with an apocrine hidrocystoma in the lower conjunctival fornix in both eyes. A 75-year-old woman exhibited tumors with a serous component, partly blue in color, in the bilateral lower conjunctival fornix in both eyes. A biopsy of the tumor in the conjunctival fornix in the left eye revealed the formation of multilocular cysts in the subepithelial stroma, lined with several layers of cuboidal epithelium, and papillary growth into the cyst lumen was also evident. Thus, a definitive diagnosis of an apocrine hidrocystoma was made. The findings in this case highlight that apocrine hidrocystomas can occur bilaterally in the lower conjunctival fornix.
