BACKGROUND To elucidate the clinicopathologic features and their implications on the immunohistochemistry in cases of molecular apocrine breast cancer (MABC). METHODS Immunohistochemical (IHC) staining for estrogen receptor (ER), human epidermal growth factor receptor 2 (HER-2), cytokeratin (CK) 5/6, epidermal growth factor receptor (EGFR), androgen receptor (AR), gamma-glutamyltrasferase 1 (...

Fox-Fordyce Disease (FFD) is a rare, chronic, pruritic, inflammatory disorder of apocrine glands. It is characterized by dome-shaped, firm, discrete, skin-colored, and monomorphic perifollicular papules. The most common sites of involvement are axillae and anogenital and periareolar regions which are rich in apocrine sweat glands. Treatment is difficult. Topical, intralesional steroids, topical...

Hidradenitis suppurativa is a chronic, recurrent, debilitating disease that presents with painful, inflamed lesions in the apocrine-gland-bearing areas of the body, most commonly the axillary, inguinal, and anogenital areas. Etiology traditionally has been attributed to occlusion of the apocrine duct by a keratinous plug; however, defects of the follicular epithelium also have been noted. Contr...

UNLABELLED Mammary hamartoma is an uncommon benign lesion. The frequency of the tumor is reported between 0.04 -1.15% and it accounts for 4.8% of all benign breast tumors. The lesion may be under-diagnosed by the clinician because of the varied clinical presentation or by the pathologist, as the microscopic appearance is not distinctive. A case of left sided mammary hamartoma in a 46-year-old f...

A 45-year-old Hispanic man presented with a 10-year history of unusual facial lesions that had spread gradually, becoming almost confluent in some areas. There was no family history of similar lesions. Physical examination revealed multiple asymptomatic, skin-colored to bluish papules and cystic nodules measuring 2 to 5 mm in diameter on the patient’s forehead and cheeks (Figure 1). Lancing pro...
