Superficial myofibroblastoma is a rare benign mesenchymal tumor which predominantly occurs in the female lower genital tract. Here we present a case of a 42-year-old female patient with prolonged vaginal bleeding. Radiological imaging revealed a well circumscribed mass in the vagina with a stalk. The patient underwent surgery and the tumor was histologically diagnosed as superficial myofibroblastoma. Notably, this is the first report of the radiological imaging of a superficial myofibroblastoma harboring a stalk arising from the vaginal wall. We compared the radiological images with histological findings and discuss major differential diagnosis of vaginal tumors. Despite the challenging nature of preoperative diagnosis of mesenchymal vaginal tumors, radiological features may aid in differentiating them from other more aggressive entities or malignant tumors.
浅表性肌成纤维细胞瘤是一种罕见的良性间叶组织肿瘤,主要发生于女性下生殖道。本文报告一例42岁女性患者,有长期阴道出血症状。影像学检查显示阴道内有一个边界清晰、带蒂的肿块。患者接受了手术,肿瘤经组织学诊断为浅表性肌成纤维细胞瘤。值得注意的是,这是首例关于起源于阴道壁且带蒂的浅表性肌成纤维细胞瘤的影像学报告。我们将影像学图像与组织学结果进行了比较,并讨论了阴道肿瘤的主要鉴别诊断。尽管间叶组织阴道肿瘤术前诊断具有挑战性,但影像学特征可能有助于将它们与其他更具侵袭性的实体或恶性肿瘤区分开来。
