DefinitionThis section has been translated automatically.

Heterogeneous group of tumors that originate from the apocrine glandular epithelium. The majority of tumors are benign. With the few sweat gland carcinomas, the assignment apocrine / eccrine is often not possible. Admittedly, it also has no clinical relevance. Adnexal tumours with apocrine differentiation show an extraordinarily large histological variability with a rather monomorphic and uncharacteristic clinical picture, which often makes their exact classification difficult. In addition, there are difficulties due to the different nomenclature. The diagnosis "adnexal tumor with apocrine differentiation" is generally a histological random diagnosis. A useful histological phenomenon for apocrine secretion is the so-called decapitation secretion. Immunohistological markers for differentiation of apocrine secretion are: GCDFP-15 (gross cystic disease fluid protein), lysozyme and LeuM1.

ClassificationThis section has been translated automatically.

The classification presented here is essentially based on the morphological criteria developed on the HE section.
