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.
