See also: apocrine gland. [G. apo-krinō, to separate] Medical Dictionary for the Health Professions and Nursing © Farlex 2012. Apocrine hidradenoma is a benign neoplasm. In rare cases, benign clear-cell hidradenomas may show lymph node involvement without disease progression.

Apocrine cells

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.

Carcinoma with apocrine differentiation (invasive apocrine carcinoma) is defined by “WHO Classification of Tumours of the Breast” as “any invasive carcinoma in which cells show the cytological features of apocrine cells” (O’Malley and Lakhani 2012).

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.

Apocrine sweat glands (apocrine being a misnomer, they are truly a merocrine gland, not an apocrine gland) function in the same way, however, their ducts lead to hair follicles, not directly to the skin surface. Apocrine secretion is less damaging to the gland than holocrine secretion (which destroys a cell) but more damaging than merocrine secretion (exocytosis).

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.

Cells with oval nuclei (myoepithelium). Stromal fragments: Spindle cells. Fluffy appearance - relatively paucicellular. Naked bipolar nuclei. Represent myoepithelial cells stripped of their cytoplasm. Apocrine metaplasia Cytology Cells of apocrine metaplasia are removed via fine needle aspirates in lesion of breast. The feature of signet ring also appear in the apocrine metaplasia and these rings are responsible for creating difference between benign and malignant apocrine metaplasia.

Sciarra, Amedeo MD *; Lopez, There are two types of sweat gland in the body: apocrine and eccrine. The size of apocrine secretory cells can vary depending on the state of secretion that Cells are characterized by typical apocrine features, namely, abundant eosinophilic granular cytoplasm and prominent/multiple nucleoli [2]. According to Steroid receptor profile: Estrogen receptor (ER)-negative (B);. Androgen receptor (AR)-positive (C). D. The tumor cells also exhibited Her-2/neu protein 1 May 2008 In fact, Principal cells of the epididymal epithelium use an apocrine mode of secretion to deliver small membranous particles named gland is composed of exocrine alveolar cells (A) and myoepithelial cells (M). into the secretion with a covering of cell membrane (apocrine secretion). morphology of apocrine cells exfoliated in breast cyst,fluid (BCI;) was studied in.

metaplasia, the distribution of ME cells in 59 metaplastic and intraductal proliferative apocrine lesions was evaluated using immunohistochemical expression of p63 and Calponin.
