Breast hamartoma is an uncommon, benign, slow-growing lesion found in all age groups after puberty. This pathological entity has a reported incidence of 1.2% of benign lesions and 4-8% of benign breast tumors in women (1, 2). It appears that with the increasing use of breast screening more hamartomas are likely to be identified. This rare pathological entity consists of a well-circum-scribed, b...

BACKGROUND Adenoid cystic carcinoma of the breast is an uncommon histologic form of breast cancer, comprising in most series less than 1% of all mammary cancers. Due to the rarity, little information about its presentation on image studies has been noted in the literature. Here we report two additional cases with emphasis on the intriguing image presentations. CASE ONE A 67-year-old woman cam...

BACKGROUND Sclerosing adenosis is a benign, usually asymptomatic lobulocentric proliferative process that involves both the epithelial and the mesenchymal component of the breast. It is commonly an incidental finding in perimenopausal women undergoing screening mammography. CASE REPORT We reported on two patients with sclerosing adenosis assessed with mammography, ultrasound, and contrast-enh...

PURPOSE The purpose of this study was to describe the breast ultrasonography (US) features and to investigate whether performing a core biopsy is warranted in young women having palpable solid breast masses. METHODS A total of 76 solid palpable masses in 68 consecutive women (≤25 years old) underwent tissue diagnosis by percutaneous core biopsy. Two radiologists, who were blinded to the clini...

Myoepithelial cells are normally present in the breast localized between epithelial cells and the basal lamina of secretory elements of the mammary duct system (1,2). Tumors derived from these cells have been described in skin, salivary glands, breast and lungs (1,2). Adenomyoepithelioma (AME) of the breast is a rare lesion, and usually affects adult female patients (1,2). Rare cases have been ...
