Apocrine carcinoma of the breast is a rare form of invasive breast cancer.
General
- Need >=90% apocrine morphology.[1]
- Worse prognosis that invasive ductal carcinoma of the breast in a large series.[2]
Microscopic
Features:[1]
- Prominent red nucleoli.
- Often multiple.[3]
- Abundant granular eosinophilic cytoplasm.
- Architecture like invasive ductal carcinomas no special type.
DDx:
- Glycogen-rich clear cell carcinoma of the breast.
- Cutaneous Apocrine Carcinoma
- A possible cutaneous apocrine carcinoma in a patient with a history of mammary apocrine carcinoma is problematic but fortunately a relatively infrequent conundrum.
- Apocrine-like carcinoma - immunoprolife doesn't fit for invasive AC (ER +ve, PR +ve, AR -ve).[2]

IHC
Smaller tumours classically:[4]
Usually:[1]
- ER -ve.
- PR -ve.
- Often HER2 +ve but can be HER2 -ve.[5]
Notes:
- Salivary duct carcinoma and cutaneous adnexal tumours can show a similar IHC profile.
- Apocrine carcioma can be a non-basal type 'triple negative carcinoma'.[6]
- May show different behaviour to other types of triple negative carcinoma.
- May respond to treatments targeting the androgen receptor.[7]
- Be careful when reading the literature in this area - is the author discussing 'molecular apocrine' (ER -ve, AR +ve) or 'morphologic apocrine' carcinoma.
- Many ductal carcinomas, NOS show AR positivity but are often ER +ve.
