In its morphology, the apocrine gland is large and spongy. tial pitfall is that cells with apocrine differentiation are generally negative. This finding is important when diagnosing atypia in columnar cell chang-es, which characteristically have apocrine features (Fig 1B). 3 In this setting, the pathologist should rely on cytologic and architectural features on H & E examination alone. Apocrine glands are found regularly in the axilla, anogenital region, the areola and nipple of the female breast, the eyelids (Moll's glands), and the external auditory canal.

A small number of cells resembling true apocrine cells are found in the breast, and they may develop carcinoma. (a) On H&E staining, apocrine cells are characterised by abundant pink, granular cytoplasm and centrally located hyperchromatic nuclei, which may have one or two prominent nucleoli. The nuclear to cytoplasmic ratio is very low. The apical portions of the cells contain coarse eosinophilic granules. Occasionally, apocrine cells may be atypical and present diagnostic difficulties. The morphologic features of six breast FNAs that contained atypical apocrine cells were analyzed and compared with benign apocrine cells in breast aspirates. Apocrine cells: granular cytoplasm and mild anisonucleosis.

Apocrine sweat glands, which are usually associated with hair follicles, continuously secrete a fatty sweat into the gland tubule. Emotional stress causes the tubule wall to contract, expelling the fatty secretion to the skin, where local bacteria break it down into odorous fatty acids. Apocrine glands have secretory tubules that form a sac-shaped lumen. This lumen is lined with simple cuboidal epithelial cells and is wider and larger than the eccrine lumen. The size of apocrine secretory cells can vary depending on the state of secretion that they are at. 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 glands form in utero, but don't go into action until puberty when they receive cues from all the hormonal stimulation taking place.
Apocrine tumor cells are almost always positive for an additional receptor called the androgen receptor. Apocrine tumors, even when triple negative, are less likely to involve the lymph nodes, are more responsive to treatment, and may have a better prognosis than more common types of invasive ductal cancer.
