The authors believe that the apocrine features displayed by many of the cancer cells in these 10 patients may explain the unusual profusion of calcium deposits. Macroscopically, apocrine carcinoma is in the form of a nodule or endo-cystic growths, often multicentric . Histologically, the tumor is defined as a carcinoma showing in more than 90% of tumor cells, cytological features of apocrine cells (mixture of varying proportions of type A cells and type B cells). The authors believe that the apocrine features displayed by many of the cancer cells in these 10 patients may explain the unusual profusion of calcium deposits.

Apocrine DCIS is often characterized by a proliferation of apocrine cells showing marked nuclear pleomor-phism with enlarged nuclei, multiple prominent nucle-oli and irregular nuclear membranes; comedo necrosis is invariably present in such cases. When these features are seen, a diagnosis of apocrine DCIS is not difficult to Apocrine epithelium has a characteristic steroid receptor profile that is estrogen receptor and progesterone receptor negative and androgen receptor positive. This combination of morphologic and Apocrine (/ ˈ æ p ə k r ɪ n /) is a term used to classify exocrine glands in the study of histology. Cells which are classified as apocrine bud their secretions off through the plasma membrane producing extracellular membrane-bound vesicles. The apical portion of the secretory cell of the gland pinches off and enters the lumen.

Apocrine-like cells form in a lining of developing microcysts, due to the pressure buildup within the lumen. The pressure build up is caused by secretions. [4] This type of metaplasia represents an exception to the common rule of metaplasia increasing the risk for developing cancer; apocrine metaplasia doesn't increase at all the possibility of getting breast cancer. Apocrine tumor cells are almost always positive for an additional receptor called the androgen receptor.
