A 72-year-old man was referred to our hospital with a complaint of a painless, gradually-enlarging lump in his left breast. On physical examination, a non-tender, poorly-demarcated firm tumor was palpable in the left breast. Intra-operatively, a 2.5×2.4×2 cm mass was excised, and the frozen section demonstrated a small, round, blue cell-type malignancy. A tumor excision was then performed. The histologic examination established the diagnosis of a primary diffuse large B cell lymphoma (DLBCL) of the breast. Male breast cancer represents < 1% of all mammary malignant tumors. Primary breast lymphomas (PBLs) have a reported incidence ranging from 0.04%-0.5% of all breast malignancies. PBLs in males are extremely rare. We report a case of a DLBCL in a 72-year-old male patient. |
