The authors report two cases of rare localization of intra muscular myxoma: one in the buttock, and the other in the lumbar area. The first case, a 58 years old woman had a four month history of a mass in the buttock. Computed tomography revealed the presence of a solid tumor. Diagnosis was based on histological examination. After surgical treatment no recurrence was observed after fourteen months. The second case was a 54 years old woman who presented a sciatica with back pain and neurological signs. The symptoms didn't response to medical treatment. Computed tomography showed an enlarged and-cystic lumbar lesion extending to the first sacral hole, with bone erosion of L3 and L4 articular apophysis and spinous process. Needle biopsy and surgical excision of the tumor were performed. Total neurological recovery was observed and no recurrence was observed after three years. The authors reminded the characteristics of this rare and benign soft tissue tumor and specified the place of magnetic resonance imaging (MRI) to establish the diagnosis which was still confirmed by histological examination of an open biopsy. Clinical follow-up revealed exceptional recurrence and no metastasis.
一例位于臀部，另一例位于腰部。第一例，一名58岁女性，臀部肿物已有4个月病史。计算机断层扫描显示存在实体瘤。诊断基于组织学检查。手术治疗后14个月未观察到复发。第二例是一名54岁女性，表现为坐骨神经痛伴背痛和神经体征。症状对药物治疗无反应。计算机断层扫描显示一个扩大的囊性腰部病变延伸至第一骶孔，伴有L3和L4关节突及棘突的骨质侵蚀。进行了肿瘤的针吸活检和手术切除。观察到神经功能完全恢复，3年后未观察到复发。作者提醒了这种罕见的良性软组织肿瘤的特征，并明确了磁共振成像（MRI）在建立诊断中的地位，最终诊断仍需通过开放活检的组织学检查来证实。临床随访显示复发罕见且无转移。
