肝吻合状血管瘤1例

Hepatic anastomosing hemangioma: A case report

背景吻合状血管瘤(anastomosing hemangioma,AH)是一种罕见的血管良性肿瘤,常累积泌尿生殖系统和椎管旁区域,极少发生在肝脏,缺乏特异性临床表现,易过度治疗.病例简介本例患者因“发现肝脏肿物2年,增大7月”就诊,术前诊断考虑局灶结节状增生,因短期内肝肿物体积增大,不排除恶变可能,在手术治疗后,确诊为肝吻合状血管瘤,术后长期随访未复发.结论肝吻合状血管瘤作为血管良性肿瘤,临床表现缺乏特异性,可表现为肝内稳定肿物短期内增大,类似恶变倾向.因此对于肝内肿物短期内进行性增大的病例,可拓宽诊疗思路,减少误诊率,避免过度治疗.

BACKGROUND Anastomosing hemangioma(AH)is a rare benign vascular tumor,which is often discovered in the genitourinary system and paravertebral region and rarely occurs in the liver.AH lacks specific clinical manifestations and is prone to overtreatment.CASE SUMMARY A 29-year-old male patient sought medical attention due to the discovery of a liver tumor for 2 years and tumor enlargement for 7 mo.The preoperative diagnosis suggested the possibility of focal nodular hyperplasia.However,due to the rapid increase in the volume of the liver tumor,the possibility of malignancy cannot be ruled out.After surgical treatment,the diagnosis was confirmed as liver AH,and there was no recurrence during long-term follow-up after surgery.CONCLUSION Hepatic AH,as a benign tumor of blood vessels,lacks specific clinical manifestations.It can manifest as a stable tumor in the liver with a rapid increase in the volume in a short period of time,similar to a malignancy.Therefore,for cases with short-term progressive enlargement of intrahepatic masses,clinicians should broaden the scope of diagnosis and treatment,reduce misdiagnosis rates,and avoid overtreatment.
