Myofibroma is a rare benign tumor typically occurring in the skin and subcutaneous tissues of the head and neck in infants and young children. The incidence of solitary intraosseous and adult myofibroma is extremely low. Although there have been a few reported cases of solitary intraosseous myofibroma in adult patients, most of these cases involved the craniofacial bones.
We present the case of a 64-years-old woman presenting with minimal pain of the right buttock and groin.
Radiographs and computed tomography showed a huge tumor spreading around the ilium, and non-uniform calcifications were noted inside the tumor. Iliac tumor biopsy was conducted, and intraosseous myofibroma was suspected. We performed surgical resection of the mass, and a final diagnosis of myofibroma with metaplastic bone production was made.
We have presented an extremely rare case of solitary intraosseous myofibroma in an adult patient.
肌纤维瘤是一种罕见的良性肿瘤，通常发生于婴幼儿头颈部的皮肤和皮下组织。孤立性骨内肌纤维瘤及成人肌纤维瘤的发病率极低。虽然已有少数成人孤立性骨内肌纤维瘤的病例报道，但其中大多数病例累及颅面骨。
我们报告了一例64岁女性患者，其右臀部和腹股沟仅有轻微疼痛。
X线片和计算机断层扫描显示一个巨大肿瘤蔓延至髂骨周围，肿瘤内部可见不均匀钙化。进行了髂骨肿瘤活检，怀疑为骨内肌纤维瘤。我们对肿块进行了手术切除，最终诊断为伴有化生骨形成的肌纤维瘤。
我们报告了一例极其罕见的成人孤立性骨内肌纤维瘤病例。
