化学感受器瘤(Chemodectoma)极为罕见,现将我们最近收治的1例胸壁化学感受器瘤报告如下:患者,女,31岁。左胸壁包块二月余于1990年10月入院。体检:左第七肋腋后线处可触及3.5×3cm 大小包块,质稍硬,固定,无明显压痛。胸片示左胸部一密度增高块影,约3×3cm 大小,第七肋骨局部皮质稍有凹陷,无骨质破坏现象。肿块穿刺细胞学检查示“小圆细胞样瘤细胞,良恶性难定”。于11月初在全麻下,沿第七肋骨走行作切口,逐层切开皮肤、皮下组织及肌层,见肿瘤位于第七肋间隙、固定,包膜完整。试图分离瘤体,但瘤组织紧贴第七肋骨下缘并深 Chemorectoma is extremely rare, and one of our recently treated chest wall chemoreceptor tumors is reported as follows: Patient, female, 31 years old. The left chest wall mass was admitted to the hospital in October 1990. Physical examination: The left seventh posterior rib can touch a 3.5×3cm mass at the posterior line. The mass is slightly stiffer and fixed. No obvious tenderness. The chest radiograph showed a density increase in the left chest, which was about 3×3 cm in size. The seventh rib had a slight cortical depression and no bone destruction. Mass puncture cytology showed that “small round cell tumor cells, benign and malignant difficult to set.” At the beginning of November, under general anesthesia, an incision was made along the seventh rib and the skin, subcutaneous tissue and muscular layer were incised layer by layer. The tumor was located in the seventh intercostal space, fixed, and the capsule was intact. Trying to separate the tumor, but the tumor tissue clings to the lower edge of the seventh rib and is deep
