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.

Apocrine features

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.

The tumor cells are polygonal containing abundant eosinophilic cytoplasm and vesicular nuclei with prominent nucleoli.
