title: Primary follicular lymphoma in a male breast: a case report.
abstract: Primary breast lymphoma (PBL) is a rare disease, particularly in males. Diffuse large B cell lymphoma is the most common PBL, while follicular lymphoma is less common. Furthermore, primary follicular lymphoma of a male breast is rarely reported. We report a male patient with primary follicular lymphoma of the breast and hepatocellular carcinoma (HCC). A 46-year-old man was diagnosed with liver cirrhosis secondary to chronic hepatitis B infection. Ten years later, he underwent segmentectomy of the liver due to HCC. Another 5 months later, he presented with a painless mass in the right chest wall. The mass was diagnosed as follicular lymphoma of the breast. The stage was IEA and he did not receive adjuvant therapy. Although only a few cases have been reported, lymphoma should be considered as a possible cause of breast mass, even in male patients.
