鼻腔恶性颗粒细胞瘤1例

Nasal malignant granular cell tumor:a case report

1病例报告患者,男,51岁,因＂右鼻腔间断出血半年＂入院。每次出血量约数滴,自止,伴鼻塞、脓涕,无头痛及其他不适。体检：口唇尚红润,右侧下鼻道中后段可见红色新生物充填,表面尚光滑,质韧,触之极易出血。鼻窦CT示：右下道占位,各窦壁骨质无破坏。各项术前常规检查均未见异常。因新生物出血明显，首先高度怀疑血管瘤，故未取活检，1周后在鼻内镜下行右鼻腔新生物摘除术，术中见新生物来源于右下甲后端，质脆（图1），术中出血约30ml。术后病理检查示：恶性颗粒细胞瘤（图2）。因患者拒绝进一步治疗，伤口恢复后出院。已随诊1年无复发。
