类似胆总管囊肿的胆总管横纹肌肉瘤:阻塞性黄疸的罕见原因
Rhabdomyosarcoma of the common bile duct mimicking choledochal cyst: a rare cause of obstructive jaundice
肝外胆道肿瘤罕见,其中以横纹肌肉瘤最常见。横纹肌肉瘤是一种软组织恶性肌肉骨骼肿瘤,是儿童非常罕见的一种胆总管恶性肿瘤。它通常表现为阻塞性黄疸和/或瘙痒。如果肿瘤没有局部浸润邻近组织,其影像学表现则类似胆总管囊肿。因此,确诊通常是在手术时或术前通过活检。早期诊断、与胆总管囊肿鉴别、尽早开始治疗对延长患者生存时间有重要意义。该文报道1例10岁男童,反复阻塞性黄疸和发热,术前诊断为胆总管囊肿,术后确诊为胆总管胚胎性横纹肌肉瘤。经手术切除、术后化疗,该患儿预后良好。故必须了解这种罕见的肿瘤可以类似先天性胆总管囊肿,并且在儿童阻塞性黄疸的鉴别诊断时应加以考虑。
Extrahepatic biliary tract tumors are rare and among them rhabdomyosarcoma is most common. Rhabdomyosarcoma is a soft tissue malignant musculoskeletal tumor and is a very rare malignancy of the common bile duct in children. It usually presents as obstructive jaundice and/or pruritus. If there is no local invasion to the adjacent tissues, the radiological appearance of the tumor lesion is like a choledochal cyst. So the diagnosis is usually made at surgery or by preoperative biopsy. It is important to diagnose early and differentiate it from choledochal cyst and start treatment as early as possible for long time survival of the patient. This case report presented a case of a 10-year-old boy with recurrent onset of obstructive jaundice and fever preoperatively who was diagnosed as choledochal cyst and postoperatively as embryonal rhabdomyosarcoma of the common bile duct. After surgical resection and postoperative chemotherapy, the child had a good prognosis. So it is crucial to know that this rare tumor can mimic congenital choledochal cyst and it should be considered in the differential diagnosis of obstructive jaundice in children.
