    Identify using standard criteria. Carcinoma, in situ or invasive, may be present. Necrosis may be seen rarely. More frequent in pregnancy May be lobular or ductal. Invasive carcinoma is present in adjacent breast in half of patients with in situ carcinoma in a fibroadenoma. Mean age of cases with carcinoma is in 40's.
