Apocrine hidrocystoma, also called apocrine cystadenoma, is a benign cystic tumor-like lesion that arises from the proliferation of apocrine glands. Clinically, it usually occurs singly as a unilocular or multilocular, dome-shaped translucent cyst. Histologically, it appears as unilocular or multilocular cysts composed of an inner layer of single or double layer of secretory columnar epithelium with decapitation secretion lying above an outer myoepithelial cell layer. Apocrine hidrocystomas mostly occur within the head and neck region and involvement of genitalia is extremely rare. This paper emphasizes the importance of considering the differential diagnosis of a genital cystic lesion. Herein, we report a case of apocrine hidrocystoma occurring in the penis and compare the clinicopathological characteristics of apocrine hidrocystoma in genitalia with the previous cases.

Apocrine hidrocystoma is a benign tumor arising from apocrine sweat gland. It presents as a solitary translucent nodule, usually on the face, head, and neck. However it is extremely rare for the apocrine hidrocystoma to arise on the extremities, and no case of apocrine hidrocystoma on lower extremity has been reported in Korean dermatologic literature. Herein, we report a case of 63-year-old male apocrine hidrocystoma that developed in ankle area with a review of the literature.

Hidrocystomas, eccrine or apocrine are rare ductal cystic benign lesions of the sweat gland. These uncommon cystic lesions are extremely rare in the external ear. Here, we discuss the clinical features and management of eccrine hydrocystoma in the external ear by describing the clinical, radiographic, pathologic features and management of an external auditory canal eccrine hidrocystoma in a 73-year-old Korean man. To the best of our knowledge, this tumor has not been reported previously in this site. Five month after surgery, there has been no evidence of local recurrence.

Eccrine hidrocystomas are benign tumors of the sweat glands that arise from cystic dilatation of the excretory sweat ducts. They may be solitary or multiple. Multiple lesions are observed as small papulonodules having prominent surfaces with a translucent intense bluish dome, localized predominantly to periorbital and malar areas. The diagnosis of multiple eccrine hidrocystomas is clinical, and surgery is the treatment of choice in the case of a single lesion. However, the treatment of multiple eccrine hidrocystomas is challenging and the outcome of conventional therapies varies. Botulinum toxin type-A (BTA) causes chemodenervation at the cholinergic nerve terminal of eccrine glands; accordingly our patient was given intradermal injections of BTA and the result was successful. Herein, we report a case of multiple eccrine hidrocystomas treated successfully with BTA; we believe that BTA can be a novel treatment option for this condition.

PURPOSE: To report a new modified method using a mixture of sodium hyaluronate and indocyanine green solution to facilitate the complete removal of a large conjunctival cyst. CASE SUMMARY: Two patients with a large conjunctival cyst on the bulbar conjunctiva were treated. In order to achieve complete removal, a mixture of 1% sodium hyaluonate and indocyanine green solution was injected through a 27-G needle into the cyst. The procedure provided excellent visualization of the cyst boundaries while maintaining cyst integrity allowing for an easy and complete resection. Apocrine hidrocystoma and a simple retention cyst were confirmed on histopathologic examination, respectively. CONCLUSIONS: During the removal of a large cyst, injecting a mixture of sodium hyaluronate and indocyanine green is effective in delineating the cyst capsule while preserving its integrity, thus aiding in the complete removal of the cyst wall.

Eccrine hidrocystomas are benign cystic dilatations with eccrine differentiation. The clinical presentation usually occurs as a solitary tense vesicle or translucent papule located predominantly on the face, whereas multiple eccrine hidrocystomas are unusual. Histologically, eccrine hidrocystoma consists of one or more partially collapsed unilocular cysts in the dermis, which show flattened epithelium that is partially lined by two layer of cuboidal epithelium. We report here on a case of the patient with multiple eccrine hidrocystomas that showed an especially generalized presentation that included the face, neck, anterior chest and both arms.
