title: [Follicular lymphoma in two brothers].
abstract: Two brothers, whose parents had a history of exposure to atomic bomb radiation, developed non-Hodgkin's lymphoma. The younger brother, a 48-year-old man, was diagnosed as having follicular small-cleaved cell lymphoma in October, 1996. He had extranodal lymphoma involvement of the right kidney, bone marrow and skin, in addition to generalized lymphadenopathy. He was treated with intermittent COP chemotherapy, and good control of the lymphoma was obtained. The elder brother, aged 50 years, was diagnosed as having follicular mixed cell lymphoma in May, 1998. He also had extranodal lymphoma involvement of the right parotid gland and bone marrow, as well as generalized lymphadenopathy. After one course of CHOP chemotherapy, he developed paresis of the lower legs and was found to have a mass at the Th5-6 vertebrae by CT scan. After four courses of CHOP chemotherapy followed by ESHAP chemotherapy and radiotherapy, he achieved complete remission, and has since been well. Follicular lymphoma occurring among siblings is rare. Further cytogenetic and molecular studies may provide a better understanding of its etiology.
