ABSTRACT
Accessory breast tissue occurs due to failure of resolution of embryonic mammary ridges present from axilla to groin bilaterally. It may be functional or non-functional. This condition is more commonly seen in the females and very few cases have been reported in males. Development of ectopic breast tissue is dependent on hormonal stimulation similar to normal breast.It remains asymptomatic usually and increases in size after a hormonal stimulation at the time or after puberty. Majority of the occurrences are completely benign, but this condition also has the potential to convert into a malignant lesion. Apocrine hidrocystoma is regarded as cystic retention and adenomatous proliferation of apocrine sweat glands. It commonly occurs on the head & neck, but can infrequently be present in other locations like axilla, vulva, penis. This is the report of case of apocrine hidrocystoma with accessory breast tissue in a 30 year old male presented with left axillary swelling. Cytomorphological assessment revealed benign epithelial lesion and a diagnosis was established only after a histopathological examination. It emphasises the role of histopathology in diagnosis of axillary breast lesions
ABSTRACT
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.

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.

Apocrine hidrocystomas (AHC) are uncommon cystic lesions of apocrine glands and are most often solitary. They are usually found in the head and neck region. Multiple AHC have been rarely reported in the literature usually in the eyelids and face. On extensive search of literature, we came across only a single case report of multiple axillary AHC. We report a case of a 31-year-old female who presented with fullness and discomfort in bilateral axillae, so a clinical diagnosis of bilateral accessory breast was made. However on histopathological examination, it turned out to be bilateral multiple AHC associated with apocrine hyperplasia.
ABSTRACT
An apocrine hydrocystoma is a translucent cystic nodule that looks like adenomatous cystic proliferation of an apocrine gland, which originated from a hair germ. Dermoid cyst is a cystic teratoma that contains developmentally mature skin appendages, such as hair follicles, sweat glands, and other tissues derived from the ectoderm. Many investigators believe that dermoid cysts re originated from the ectoderm, specifically the hair germ cells. A 58-year-old woman was presented with a purple, asymptomatic, dome-shaped nodule on her right lower eyelid that had been slowly increasing in size for several years. Histopathological examination revealed two well-demarcated cysts: one was lined with stratified squamous epithelium with mature hair and sebaceous glands and the other contained large cystic spaces, which papillary projections extended. We report a rare case of a dermoid cyst, combined with an apocrine hydrocystoma, occurring in the right lower eyelid.

A 36-year-old female patient with a mass in the coccygeal region underwent surgical removal of the mass, and this revealed a hybrid cyst in coexistence with a glomus coccygeum. This unusual cutaneous cyst had an epithelial lining composed of keratinizing, stratified squamous epithelium with an intact granular layer immediately adjacent to apocrine cells, and the apocrine cells showed the characteristic features of "decapitation secretion". The glomus coccygeum, which is a minor finding in specimens from the sacral area and it may represent a diagnostic challenge to the unaware observer, was incidentally identified in the dermis. The glomus coccygeum was located beneath the epithelial transition area of the hybrid cyst. Immunohistochemical analysis revealed that the cytoplasm of the epithelioid glomus cells was positive for smooth muscle actin, and these epithelioid glomus cells were arranged in concentric layers around blood vessels, and the cellular stroma surrounding the glomus bodies were positive for S-100 protein.

A 28-year-old woman presented with multiple, asymptomatic, erythematous to bluish papules located on the chest. Histopathologically, three round, well defined cystic structures were seen on the upper and lower dermis. The first cyst was milia, the second was apocrine hidrocystoma and the other, largest cyst was an eruptive vellus hair cyst (EVHC). A diagnosis of multiple pilosebaceous cysts combined with apocrine hidrocystoma was made. Since the milia and EVHC originate from the pilosebaceous unit, and the apocrine duct opens to the pilosebaceous orifice, we suggest that they can occur simultaneously in the same unit.

A 7-year-old female was presentd with two black papules and linear pigmentation between papules on the vulva. No other abnormalities were found in her personal and family history. Histopathological examination was consistent with the apocrine hidrocystoma and the pigment in the luminal cells was iron negative and Fontana Masson positive, confirming its melanin nature. We herein report a 7-year-old female patient with pigmented apocrine hidrocystoma occuring on the vulva with the evidence of melanin as the underlying mechanism of the pigmentation.

Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and the cyst wall of this tumor consists of columnar to cuboidal cells with a decapitation secretion indicative of apocrine secretion. A 5-year-old boy had a translucent, flesh-colored cystic nodule, 5x2x2mm in size, on the glans penis near the urethral meatus for 4 years. Although apocrine hidrocystoma of the glans penis is very rare, characteristic histopathological features make it easy to diagnose as apocrine hidrocystoma of glans penis, which should be differentiated from the median raphe cyst of the penis.

Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and another name for it is apocrine cystadenoma. A 48-year-old female patient had a solitary, translucent red-brownish cystic nodule, 10 × 6 × 7mm in size, on the periorbital area of her left eye. The lesion had enlarged very slowly for 25 years. We excised the lesion and identified it as apocrine hidrocystoma. This is a case of apocrine hidrocystoma with typical clinical and histopathological findings.

A 26 year old female presented complaining of a pea-sized nodule on her left lower eyelid for 10 years duration. Histopathological study showed several cysts in the dermis surrounded by secretory cells. The cysts were filled with decapitatory secretions. Positive staining with carcinoembrynic an tigen(CEA) was detected by immunoperoxidase technique. These clinical and histopathological findings suggest apocrine hidrocystoma developed on the left lower eyelid.
