头颈部化学感受器瘤的临床病理分析

A CLINICOPATHOLOGIC STUDY OF CHEMODECTOMA IN THE HEAD AND NECK

头颈部化学感受器瘤较少见，作者自１９８４年至１９９０年对共收治的９例进行分析，其中鼓室、颈静脉球体６例，咽侧部２例，声带１例。患者年龄平均４０岁，男女之比为１：２。由于本病病程较长，症状各异，诊断较为困难，对部分病理形态异形大，易误诊为癌、血管瘤的病例，可借助于免疫组化来确诊。化学感受器瘤的治疗，首选手术，放疗仅作为辅助手段。此瘤的预后，因其良恶性问题尚有分歧，一般认为，该瘤在病理形态上属良性，临床表现上呈浸润性生长，可破坏邻近组织及骨壁，向颅内侵犯。９例中２例失访，７例均健在。
