An incidental finding of napsin A-positive breast carcinoma with apocrine features during workup for metastatic cancer in an axillary lymph node led to our investigation of the incidence of napsin A expression in breast carcinomas, focusing on those with apocrine features.
Apocrine carcinoma of the breast Apocrine carcinoma of the breast is a rare form of invasive breast cancer. Apocrine carcinoma of the breast. Diagnosis in short.
External links. 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. Antineoplastic Agents / therapeutic use. Biomarkers, Tumor / metabolism*.
Apocrine epithelium has a Invasive apocrine carcinoma (AC), a pathological type of invasive ductal carcinoma (IDC) of the breast, is defined as a breast tumor composed of epithelium with apocrine differentiation in more than 90% of the tumor cells and accounts for 0.3%‐4% of all breast cancer. 1, 2 It is well known that AC tends to represent a unique hormone receptor profile—progesterone receptor (PR)‐negative, estrogen receptor (ER)‐negative, and androgen receptor (AR)‐positive. 3 The overexpression of 2018-01-29 · Apocrine cells are known to produce membrane-bound vesicles during their secretions. Apocrine cells collectively form the apocrine gland. Apocrine glands are inactive before puberty. They secrete substances indirectly into the external skin surface. Apocrine glands secrete a thick clear fluid.

Apocrine metaplasia of the breast is a benign breast condition and is sometimes considered part of or associated with fibrocystic change.It is a common finding in the female breast, particularly after the age of 25, and many regard it as a normal component of the breast.

Histopathological features: Apocrine carcinoma is lobulated and located in the dermis, frequently also invading subcutaneous fat (Fig. 9 A). It is poorly circumscribed with infiltrative borders. The tumor cells are polygonal containing abundant eosinophilic cytoplasm and vesicular nuclei with prominent nucleoli. Limit diagnosis to tumors with widespread apocrine change and obvious malignancy Type A cells: abundant granular and intensely eosinophilic cytoplasm, granules are PAS+ diastase resistant, nuclei vary from globoid with prominent nucleoli to hyperchromatic
An apocrine sweat gland (/ ˈ æ p ə k r ə n,-ˌ k r aɪ n,-ˌ k r iː n /; from Greek apo– "away" and krinein "to separate") is composed of a coiled secretory portion located at the junction of the dermis and subcutaneous fat, from which a straight portion inserts and secretes into the infundibular portion of the hair follicle.
