頭頸部髓外漿細胞瘤—三例報告

Extramedullary Plasmacytoma of the Head and Neck - Report of Three Cases

摘要


髓外漿細胞瘤屬罕見之漿細胞惡病質,為一侵犯黏膜下組織的局部腫瘤。80%發生於上呼吸消化道,約佔頭頸部非上皮細胞腫瘤的4%。當病理組織切片證實為漿細胞腫瘤時,需對病患做一整體的評估,檢查項目包括:血清及尿液的免疫電泳檢查、骨骼X光檢查、骨髓切片等,以排除多發性骨髓瘤的可能性,因二者在治療方法及預後都有極大的差異。馬偕醫院耳鼻喉科7年間共發現3例,其中1例位於鼻咽,另2例在鼻腔。參考各有關文獻後,對此腫瘤臨床上所具有的特性提出討論。

並列摘要


Extramedullary plasmacytomas of the head and neck are uncommon plasma cell dyscrasias. They are localized, submucosal tumors. Four fifth occur in the upper aerodigestive tract. The neoplasms account for up to 4% of non-epithelial tumors of the nasal cavity, paranasal sinuses and nasopharynx. The diagnosis of extramedullary plasmacytoma can only be confirmed after the exclusion of multiple myeloma by serum and urine protein electrophoresis and immunoelectrophoresis, skeletal survey and marrow biopsy. Three patients with extramedullary plasmacytoma of the head and neck are presented and the literature is reviewed.
