Breast cancer in men is rare, poorly known by the general population, the breast lesion is often neglected, the patient consults only at an advanced stage of evolution with significant local extension and even secondary localization of metastases. we report the case of a 65 year old patient, who consulted late after 3 years of evolution for an ulceration of the right breast revealing a breast carcinoma with lymph node, pulmonary and bone metastases. this case shows the interest to sensitize the general population on the existence of breast cancer in men as well as women, and the importance of self-examination and early consultation for any abnormal lesion of the breast.
