目的探讨成人膀胱横纹肌肉瘤(rhabdomyosarcoma,MRS)的诊治要点,以减少误诊误治。方法对我院收治的1例成人膀胱MRS的临床资料进行回顾性分析。结果本例因尿急、尿频2年入院。膀胱影像学检查均示膀胱缩小,壁呈广泛且明显不规则增厚。膀胱镜检查腔内未见异常肿块,活组织病理检查示黏膜组织慢性炎。按慢性膀胱炎治疗2周,症状无改善。2个月后出现血尿、排尿困难、中度贫血、肾功能不全等再次入院治疗,行膀胱镜检查仍未见明显肿块及出血点,随机取活检,病理检查确诊膀胱MRS,放弃治疗出院。结论成人膀胱MRS恶性程度高。早期症状体征表现不明显,易误漏诊,及时行多部位膀胱镜活检,有利于及早确诊。
Objective To investigate the diagnosis and treatment of rhabdomyosarcoma (MRS) in adults and to reduce the misdiagnosis and mistreatment. Methods The clinical data of 1 adult bladder MRS treated in our hospital were analyzed retrospectively. The results of urinary urgency, urinary frequency 2 years hospitalization. Bladder imaging showed reduced bladder, wall was extensive and obvious irregular thickening. No cystoscopy cyst abnormal lumps, biopsy showed mucosal chronic inflammation. Chronic cystitis treatment for 2 weeks, no improvement in symptoms. 2 months later hematuria, dysuria, moderate anemia, renal insufficiency and other hospitalized again cystoscopy still no obvious mass and bleeding, random biopsy, pathology confirmed bladder MRS, to give up treatment and discharge. Conclusion Adult bladder MRS have a high degree of malignancy. Symptoms of early symptoms is not obvious, easy to missed diagnosis, timely multi-site cystoscopy biopsy, is conducive to early diagnosis.
