乳腺型肌纤维母细胞瘤(MTMF)是一种罕见的间充质细胞良性肿瘤,发生在腹股沟区,腹壁,臀部,回来,和阴道壁。当腹股沟区域出现软组织肿块时,可能会误诊为腹股沟疝,特别是如果它是无症状的。我们报告了一例发生在腹股沟区的乳腺型肌纤维母细胞瘤的罕见病例。该患者是一名40岁的男性,两年前发现右腹股沟区域肿胀,并咨询了附近的医疗诊所。他被诊断为右腹股沟疝,并转诊到我们医院。在体检时,在右腹股沟区域观察到突出,由于难以还原,进行了紧急手术,怀疑肠道嵌顿.术中,没有发现腹股沟疝,但是发现了一个流动的黄色肿块。没有恶性特征,肿块被切除了。病理检查提示乳腺型肌纤维母细胞瘤。当我们检查有腹股沟肿胀的病人时,重要的是不仅要考虑腹股沟疝,还要考虑其他疾病,如软组织肿瘤。
Mammary-type myofibroblastoma (MTMF) is a rare benign tumor of mesenchymal cells that occurs in the inguinal region, abdominal wall, buttocks, back, and vaginal wall. When a soft tissue mass develops in the inguinal region, there may be a risk of misdiagnosing it as an inguinal hernia, especially if it is asymptomatic. We report a rare case of mammary-type myofibroblastoma occurring in the inguinal region. The patient was a 40-year-old male who noticed swelling in the right inguinal region two years prior and consulted a nearby medical clinic. He was diagnosed with a right inguinal hernia and referred to our hospital. On physical examination, a protrusion was observed in the right inguinal region, and due to difficulty in reduction, emergency surgery was performed, suspecting intestinal incarceration. Intraoperatively, no inguinal hernia was found, but a mobile yellowish mass was identified. There were no malignant features, and the mass was excised. The pathological examination revealed mammary-type myofibroblastoma. When we examine a patient with a complaint of inguinal swelling, it is important to consider not only inguinal hernia but also other conditions such as soft tissue tumors.
