ABSTRACT

Mucinous carcinoma represents 1 to 7% of breast cancers and may have clinical and mammographic characteristics of a benign lesion. Histologically, there are two types of colloid carcinoma: pure colloid carcinoma, in which there is no infiltrating ductal carcinoma component, and mixed colloid carcinoma, in which there are foci of infiltrating ductal carcinoma in addition to the colloid component. This distinction is crucial because of its prognostic value. Clinically, mucinous carcinoma, like most breast cancers, is revealed by a palpable breast nodule usually located in the superolateral quadrant. Node invasion is the main prognostic marker for colloid carcinoma of the breast. The diagnosis is made on the basis of mammography and breast ultrasound. The immunohistochemical study of hormone receptors often revealed a strong presence. Therapeutic management is based on surgery with or without chemotherapy and adjuvant hormonal therapy. In this work, we review the different epidemiological, diagnostic, anatomopathological, therapeutic and evolutionary particularities of mucinous breast carcinoma.
