Unusual breast lesions are a diagnostic challenge. These lesions include systemic diseases, benign tumours, primary or metastatic malignant tumours. Lymphadenopathy is the most common finding associated to collagen disease. Diabetic mastopathy results in a very hard mass, with US aspect of a hypoechoic mass, attenuating, while imposing for a malignant tumour. The fibromatosis can also simulate a primitive cancer (irregular dense mass in mammography, hypoechoic and attenuating in sonography). The giant cells tumour generally results in a regular, heterogeneous mass. The phyllodes touch the young woman; they are characterized by a benign mass type, round, increasing size rapidly. Medullar carcinoma is important to diagnose because of its best forecast. It carries out a round or oval mass, with regular shapes. The histological diagnosis is difficult. The lymphoma appears as one or more well circumscribed masses, not calcified. Mammary metastases produce regular, not very dense masses or a diffuse cutaneous thickening. The radiologist must familiarize himself with these aspects in order to avoid the traps diagnoses and to allow an early and appropriate management.
