Adenomyoepithelioma is an uncommon pathology of the breast. It is usually benign.
General
- Rare lesion consisting of epithelial and myoepithelial elements.
- May occur in other sites, e.g. tonsil.[1]
- May be benign or malignant.[2][3]
Note:
- Possibly the same tumour as epithelial-myoepithelial carcinoma of the salivary gland.[4]
Microscopic
Features:[5]
- Well-circumscribed.
- Glandular architecture with:
- Easily identifiable myoepithelial cells - with clear cytoplasm - key feature.
- Eosinophilic cuboidal epithelial cells.
- Eosinophilic basement membrane material between glands.
DDx:
- Invasive ductal carcinoma of the breast (on core biopsy).
- Mammary pleomorphic adenoma.
- Ductal adenoma.
- Tubular adenoma of the breast - does not have a prominent (clear) myoepithelial component.
- Sclerosing adenosis.[6]
