Klinefelter's syndrome is known to be associated with various malignancies including male breast cancer and germ cell tumour. We report a patient with Klinefelter's syndrome who developed a primary B-cell lymphoma of the central nervous system (CNS). To the best of our knowledge, this is the first case of primary CNS lymphoma in Klinefelter's syndrome.

Primary lymphoma of the male breast is extremely rare. We report a case of a diffuse large B-cell lymphoma in a male patient. A 67-year-old man presented with a palpable mass in the right breast and ipsilateral axillary lymphadenopathy. At operation a 6 x 5 x 4-cm mass was excised, and a frozen section demonstrated malignancy. A modified radical mastectomy was then performed, together with axillary lymph node clearance. Histological examination established the diagnosis of a primary non-Hodgkin's lymphoma of the breast. The patient was referred for chemotherapy and died a year later from systemic disease involving the adrenals. The importance of early diagnosis is emphasized; this should be based on an excisional biopsy or aspiration cytology. As patients with primary breast lymphoma (PBL) have a better prognosis than those with carcinoma of the breast or patients with extranodal lymphomas, a multidisciplinary approach including surgery, radiotherapy, and chemotherapy when needed would result in a more favorable outcome.

Lymphoma of the breast is unusual, and synchronous bilateral lymphoma and carcinoma of the breast is extremely rare. We present the case of a 51-year-old woman who found a mass in her left breast. Ultrasound scan findings revealed nodules at the 2 o'clock position in her left breast and focal dilation of the duct at the 8-9 o'clock and 10 o'clock position in her right and left breasts, respectively. A left breast ultrasound-guided core needle biopsy and right breast segmental excisional biopsy were performed. Pathological and immunohistochemical examination revealed left breast invasive ductal carcinoma and right breast diffuse large B-cell lymphoma of the non-germinal center type. Pathological examination of the left breast modified radical mastectomy specimen revealed synchronous invasive ductal carcinoma (grade III) and diffuse large B-cell lymphoma. The patient received chemotherapy and bone marrow transplantation in another hospital. Based on a review of the relevant literature, we discuss the diagnosis, clinical features, treatment, and prognosis of synchronous breast lymphoma and invasive ductal carcinoma.
