complex fibroadenoma

Friday 23 October 2015

Complex fibroadenoma is a sub type of fibroadenoma harbouring one or more of the following features:
- epithelial calcifications
- papillary apocrine metaplasia
- sclerosing adenosis and
-  cysts larger than 3 mm

They fall under the broad group of "adenomatous breast lesions".

Complex fibroadenomas are often smaller than simple fibroadenomas (1.3 cm compared with 2.5 cm in simple fibroadenomas).

When histopathology on core biopsy reveals a higher-risk lesion, such as atypical lobular hyperplasia, excisional biopsy may be indicated to rule out malignancy.
