Apocrine carcinoma is a cancer of a sweat gland.. Apocrine carcionoma most often develops under the arm (the axilla), but it can develop on the scalp or other parts of the body. The cause of apocrine carcinoma is unknown. Apocrine carcinoma usually appears as a single, small, painless bump that can vary in color and slowly increases in size. The average age at the time of diagnosis is 62 years. Other carcinoma subtypes, WHO classified: acinic cell adenoid cystic apocrine cribriform invasive papillary male invasive microinvasive micropapillary mixed NST mucinous mucinous cystadenocarcinoma mucoepidermoid polymorphous secretory carcinoma secretory carcinoma tall cell carcinoma with reverse polarity tubula Apocrine carcinoma of the breast is a rare, Definition special type of breast carcinoma showing distinct morphologic, immunohistochemical and molecular Mammary apocrine cells have abundant eosinophilic genetic features.

Apocrine carcinoma of the breast is a rare malignant tumor whose incidence varies between 0.3% and 4% of all female's breast cancer [ 1 ]. This tumor is exceptional in men. Indeed, only a dozen cases have been described in the literature [ 2 ]. Like our patient, the average age of onset is between the sixth and seventh decade [ 1 ] Apocrine metaplasia is a very common finding in the female breast after the age of 25. It is so common that many people regard it as a normal component of the breast. This, however, is only really the case in apocrine sweat glands of the axilla and in the peri-areolar apocrine glands. The apocrine cell does, however, contribute to a number of different breast lesions, some of which are very.

Primary apocrine sweat gland carcinoma (PASGC) is a rare subtype of sweat gland carcinoma, with approximately 50 cases reported in the literature thus far [1-5].It occurs mostly in apocrine-dense regions such as the axilla and anogenital areas, although it has also been reported to occur in less typical locations such as the forehead, wrists, ear canals, eyelids, trunk, feet, toes, and fingers. Invasive apocrine carcinoma (IAC) of the breast is a rare subtype of breast malignancy. Its incidence is not well known, but it is approximately less than 1% to 4%. For these reasons, there are few reports and little information on the radiologic appearance of IAC. Furthermore, most of the case reports show malignant features which are similar to invasive ductal carcinoma (IDC) Invasive breast carcinoma of any type, with or without ductal carcinoma in situ (DCIS) Includes microinvasive carcinoma and carcinoma with neuroendocrine ___ Apocrine adenocarcinoma .

Apocrine Adenoma of Breast is a benign tumor of breast affecting the breast tissue, which is mostly observed in younger women.

Apocrine carcinoma of breast is a very rare form of breast malignancy represent about 0.4% of all invasive ductal carcinoma (IDC). Though clinical presentation and gross appearance are indistinguishable from classic IDC, they have distinct cytological, histopathlogical and immunohistochemical features. Tumor cells are characterized by typical apocrine features large cells with abundant. Apocrine carcinoma is a morphologically distinct type of invasive breast cancer characterized by large cells with a low nuclear to cytoplasmic ratio and abundant eosinophilic granular cytoplasm . The cytoplasm is abundant with a coarsely granular eosinophilic appearance . The nuclei are large and pleomorphic with prominent nucleoli Apocrine carcinoma is a very rare form of breast malignancy with an incidence of <1% of female invasive breast carcinoma. We report a case of apocrine carcinoma in a 42-year female with marked adenosis showing apocrine metaplasia and discuss the criteria to diagnose apocrine carcinoma with the emerging concept of androgen receptor positivity with its implication on treatment and management of. Although less commonly, the term apocrine carcinoma is also used to refer to a rare form of breast cancer that forms in the ducts and makes its presence known with apocrine secretions [source: Japaze ]. Apocrine carcinomas first appear as firm cysts right under the skin, which has usually turned red or purple in that distinct spot Apocrine Carcinoma. Apocrine morphology may be focally present in a variety of breast carcinomas, including ductal, lobular, mucinous, tubular, medullary and others. The term apocrine carcinoma is reserved for breast carcinomas in which majority of the tumor cells have apocrine morphology - consisting of abundant densely eosinophilic.

(Resembles tall cell papillary thyroid carcinoma). Express both high an Three cases of apocrine carcinoma of the breast were investigated by light and electron microscopy. Histologically, the tumor cells were shown to have eosinophilic granular cytoplasm and occasional cytoplasmic snouts protruding into the lumen. Ultrastructurally, light and dark tumor cells were identified, and there were many lysosome-like dense bodies of various sizes and small dense granules. Methods Patients ages 17-91 from 1973 to 2006 were identified in the SEER registry and excluded breast and non-cutaneous neoplasms. Data analyzed included basic demographics, survival, surgical therapy, and stage. Results A total of 186 patients with apocrine adenocarcinoma were identified Some breast lesions are associated with apocrine phenotype features, such as atypical apocrine adenosis (AAA), apocrine ductal carcinoma in situ (DCIS), and invasive carcinoma with apocrine features. AAA is a rare benign breast lesion and should not be regarded as a direct histologic precursor to invasive breast carcinoma (B) CK5/6 IHC is negative in apocrine metaplasia involving papilloma. Because apocrine cells are typically negative for CK5/6, a negative result should not be interpreted as atypia. This constitutes a possible pitfall when interpreting CK5/6 stain in apocrine lesions (× 50). (C) ER stain shows scattered positivity in benign breast tissue (× 200)

Currently, accurate diagnosis of breast lesions depends on a triple assessment approach comprising clinical, imaging and pathologic examinations. Fine needle aspiration cytology (FNAC) is widely adopted for the pathologic assessment because of its accurracy and ease of use. While much has been written about the atypical and maliganant categories of FNAC diagnosis, little covers the non. apocrine carcinoma: 1. a carcinoma composed predominantly of cells with abundant eosinophilic granular cytoplasm, occurring in the breast or other sites; 2. a carcinoma of the apocrine glands

  2. Mucinous carcinoma of the breast — sometimes called colloid carcinoma — is a rare form of invasive ductal carcinoma (cancer that begins in the milk duct and spreads beyond it into nearby healthy tissue). In this type of cancer, the tumor is made up of abnormal cells that float in pools of mucin, a key ingredient in the slimy, slippery.
  3. 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).More strictly, it is a breast cancer characterized by apocrine morphology (abundant eosinophilic and granular cytoplasm, centrally.

Skin tumors of the axilla are often suspected to be metastasis of other neoplasms in particular breast cancer to harbor triple-negative invasive ductal carcinoma with apocrine differentiation derived from an accessory breast at the axilla.
