Giant Apocrine Hidrocystoma of the Anogenital Region: A Case Report
Keywords:
apocrine gland, hidrocystoma, adnexal neoplasmAbstract
Hidrocystomas are rare, benign, cystic lesions of the sweat glands. They result from proliferation of the apocrine secretory coil or eccrine duct. Hidrocystomas are of two types, apocrine and eccrine depending on the origin of the cyst. These commonly occur over the head and neck region and their size ranges from few millimeters to a centimeter in diameter. The tumours more than two centimeters in diameter are called as giant apocrine hidrocystoma. The occurrence of such giant apocrine hidrocystoma over the anogenital region is rare and we found that there is paucity of literatures regarding the apocrine hidrocystoma having atypical presentation. The differential diagnosis of the cystic neoplasms often poses a diagnostic challenge in this site.
Hence, we present the case of giant apocrine hidrocystoma in a 23-year-old male patient measuring 2.5x2.3 cm in size and located in the anogenital region. The excisional biopsy of the lesion was performed. Histopathologically, the lesion showed double-layered secretary epithelium of apocrine type.
 Here, we discuss a rare case of giant apocrine hidrocystoma over the anogenital region and highlight its histopathological features and its close differential diagnosis of cystic lesions over the anogenital region.
