Apocrine carcinoma of the breast is a rare, special type of breast carcinoma showing distinct morphologic, immunohistochemical and molecular genetic features. apocrine carcinoma varies from < 1% to 4%.30–32 Such variability in incidence is likely to be a result of the lack of well-deﬁned diagnostic criteria. Rosen has stipulated that the term should be reserved for ‘neoplasms in which all or nearly all the epithelium has apocrine cytologic features’.33 Focal apocrine … Considering the clinicopathogical features and prognosis, it is reasonable that triple‐negative apocrine carcinoma (TNAC) should be distinguished from TNBC. 6, 7 Because TNAC is a rare pathological type of TNBC, the clinicopathological features and prognosis of these patients have only been reported in a limited number of studies—case reports or studies recruiting a small number of patients.

There are no distinguishing mammographic features, although a new or enlarging lobular, microlobulated mass or heterogeneous calcification cluster may sometimes represent apocrine metaplasia. When this is seen, a needle biopsy is required for definitive diagnosis 1.

Apocrine features are found in a high percentage of breast specimens, both in biopsies and resections, involving benign, innocuous lesions and invasive breast cancer. Epithelial cells with apocrine features can look atypical and, because there are no reliable biomarkers of malignancy, definite categorization of these lesions is often challenging. Abstract Sweat and sebaceous glands have important roles in maintaining homoeostasis. In addition to their well-established role in thermoregulation, eccrine sweat glands have immunomodulatory, antimicrobial and excretory functions. Apocrine sweat is an odorless viscous fluid that contains precursors of odoriferous substances.

Apocrine ductal carcinoma in situ (ADCIS) has been called a special type of ductal carcinoma in situ (DCIS) because the histologic grading is considered difficult using the classification schemes that have been proposed for common DCIS. However, ADCIS encompasses a spectrum of lesions with different … 2019-05-07 2012-03-26 PURPOSE: To describe the mammographic features of apocrine carcinoma and assess the patterns of calcifications associated with these lesions. MATERIALS AND METHODS: Clinical and mammographic features from 17 patients with apocrine carcinoma were retrospectively reviewed. Special attention was paid to the presence of mixed form, diffusely scattered microcalcifications on mammograms.

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.

MATERIALS AND METHODS: Clinical and mammographic features from 17 patients with apocrine carcinoma were retrospectively reviewed. Special attention was paid to the presence of mixed form, diffusely scattered microcalcifications on mammograms. RESULTS 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.
