Intramuscular myxoma is a rare benign soft tissue tumour of mesenchymal origin, which appears as a painless mass of slow growth. Early diagnosis is important in order to differentiate it from other entities, especially soft tissue sarcoma.
Two cases, both women with a mean age of 52.5 years (range 40-65) are presented. The first was seen due to growth of a gluteal mass, and the second by coccydynia. Computed tomography and nuclear magnetic resonance were the diagnostic tests of choice. In one case, where there was a single but large lesion, radical extirpation of the gluteal muscle was chosen. In the other case, in which the lesions were multiple, individualised excision of cysts was performed. Postoperative functional limitation was low in both types of surgery, with good oncological results being obtained.
Intramuscular myxomas are benign lesions. There are no cases of malignancy or recurrence due to incomplete resection. It has to be determined whether they are single or multiple, since in the latter case, they could be due to syndromes such as Mazabraud syndrome, which is associated with bone fibrous dysplasia, or Albright syndrome that is also associated with pigmented skin spots.
肌内黏液瘤是一种罕见的间叶组织起源的良性软组织肿瘤，表现为生长缓慢的无痛性肿块。早期诊断对于将其与其他疾病，尤其是软组织肉瘤相鉴别很重要。
介绍了两例病例，均为女性，平均年龄52.5岁（范围40 - 65岁）。第一例因臀部长有肿块就诊，第二例因尾骨痛就诊。计算机断层扫描和核磁共振是首选的诊断检查方法。其中一例有单个但较大的病变，选择了臀肌根治性切除。另一例病变为多发性，对囊肿进行了个体化切除。两种手术方式术后功能受限程度均较低，肿瘤学效果良好。
肌内黏液瘤是良性病变。没有因切除不完全而导致恶性或复发的病例。必须确定它们是单发还是多发，因为在后一种情况下，可能是由于诸如与骨纤维发育不良相关的马扎布罗德综合征或也与色素沉着皮肤斑相关的奥尔布赖特综合征等综合征引起的。
