RESUMEN
AIM: Breast cancer in men is a very rare neoplasm accounting 1% of all breast cancer with an incidence ratio of 1:100 of men to women and about 1% of all malignancies in men. On the basis of the literature review the authors tried to determine the main characteristics of this rare neoplasm in terms of epidemiology, diagnosis, prognosis, treatment and survival. METHODS: The authors report the experience of the Breast Unit of the San Giovanni Addolorata Hospital in Rome, where 4 cases of male breast cancer were observed and treated over 784 breast cancers. RESULTS: All tumours were ductal carcinomas. The extent of disease was as follows: 3 cases with stage I and 1 case with Stage IIIB; in two cases estrogen and progesterone receptors expression was 100% and in the other two cases it was 20-80%. Median follow up was 57.5 months. At present, after 6-year follow up the three patients with stage I are in good conditions; the patient with stage III died after 27 months with metastatic disease. CONCLUSIONS: Surgical treatment remains the gold standard in male breast cancer. The prognosis for males with breast cancer is similar to female patients on equal terms of stage of disease. Adjuvant therapy is based on retrospective studies of male breast cancer conducted over the past 20 years using the guidelines for breast cancer in women.

Primary non-Hodgkin's lymphoma of the breast is a rare entity representing 0.04-0.5% of all malignant female breast tumors, less than 1% of all patients with non-Hodgkin lymphoma and approximately 1.7-2.2% of all patients with extranodal non-Hodgkin lymphomas. A 75 years old patient presented with masses in the lateral part of the left breast for 6 weeks. Ultrasound detected 3 masses suggesting fibroadenomas while mammography set the suspicion of breast multicentric carcinoma. Fine needle aspiration cytology of one mass showed low grade lymphoma subsequently confirmed with histopathology which diagnosed extranodal non-Hodgkin lymphoma MALT type CD 20+/CD 79a+/CD 3-/Bcl 2- and index of proliferation Ki 67=30% (stage IE). Primary non-Hodgkin lymphomas of the breast, though rare, should be considered in the differential diagnosis of breast malignancies. At present, a standard treatment doesn't exist yet; low grade lymphomas should be managed with excision biopsy and/or local radiation therapy, while high grade lymphomas should be managed with chemotherapy in association with radiation therapy.
