Uterine Inflammatory Myofibroblastic Tumor: A Case Report.
子宫炎性肌纤维母细胞瘤(IMT)是一种罕见的间叶源性肿瘤,通常呈惰性病程,但少数病例可表现为侵袭性行为。最常见的临床表现是异常子宫出血和盆腔不适。影像学特征缺乏特异性,通常表现为子宫肌层肿块伴不均匀强化,偶可见浸润性边缘。组织学上,IMT由梭形肌纤维母细胞构成,位于黏液样至致密间质中,伴有炎性细胞浸润,且常表现为间变性淋巴瘤激酶(ALK)基因融合及ALK阳性。主要治疗方式为手术切除,对于特定病例,ALK抑制剂可作为治疗选择。
Uterine inflammatory myofibroblastic tumor (IMT) is a rare type of mesenchymal tumor that usually follows an indolent course, although it can behave aggressively in a minority of cases. The most common clinical presentations are abnormal uterine bleeding and pelvic discomfort. Radiographic features are non-specific, typically showing a myometrial mass with heterogeneous enhancement and, occasionally, infiltrative margins. Histologically, IMTs are composed of spindle myofibroblasts in a myxoid to compact stroma with an inflammatory infiltrate, and they often exhibit anaplastic lymphoma kinase (ALK) gene fusions and ALK positivity. The main treatment approach is surgical excision, with ALK inhibitors as a therapeutic option in selected cases.
