精巣原発悪性リンパ腫の2例

Abstract

症例1:63歳男.左陰嚢内容の無痛性腫脹を主訴とし入院.左精巣腫の診断で左高位精巣摘除術を施行, 病理組織学的に大型の類円形腫瘍細胞が認められ, セミノーマと診断されたが, 免疫組織学的検査でdiffuse large cell type B細胞系の非ホジキンリンパ腫と診断された.化学療法も施行され, 術後12ヵ月現在再発を認めない.症例2:63歳男.無痛性右陰嚢内容腫脹を主訴, 右精巣腫瘍として摘除, リンパ球B細胞系腫瘍細胞が瀰漫性に増殖diffuse medium cell type B細胞系の非ホジキンリンパ腫と診断された.胸骨後面に腫瘍が認められ, 化学療法後著明に縮小した

Two cases on non-Hodgkin's malignant lymphoma (NHL) of the testis are reported. A 63-year-old man with left painless scrotal swelling underwent orchiectomy. Although prophylactic irradiation was performed under the diagnosis of seminoma, subsequent immunohistochemistry revealed NHL, large diffuse cell type (B type). He had stage IEA disease. Chemotherapy with cyclophosphamide, adriamycin vincristine and prednisolone was performed. The second case was in a 63-year old man with right painless scrotal swelling. Orchiectomy revealed NHL, diffuse medium cell type (B type). Because of tumor in the retrosternum, he had stage IIIEA disease. Chemotherapy and irradiation to the contralateral testis was performed.
