脾脏炎性肌纤维母细胞瘤二例诊治分析

目的 探讨脾脏炎性肌纤维母细胞瘤（splenicinflammatorymyofibroblastictumor,SIMT）的临床、CT、病理学表现及治疗与预后。方法 回顾性分析2例SIMT的临床资料并复习文献。结果 2例临床主要表现为左上/中腹部隐痛不适,查体左腹部轻度压痛,1例触及质韧肿块。CT均表现为脾脏单发低密度肿块,边界较清晰,增强轻至中度渐进式不均匀强化,未见周边侵犯、腹腔积液及肿大淋巴结。2例均经脾切除完整切除病灶,病理学显示肿瘤由增生的梭形细胞、慢性炎细胞及胶原纤维组成;免疫组化Vimentin、SMA、CD8及CD30（+）。术后分别随访19个月及32个月,未见复发及转移。结论 SIMT罕见,临床及CT表现缺乏特异性,最终需病理学确诊。脾脏切除术可以达到根治切除的目的,由于少数IMT术后可复发,极少数可发生转移,术后一般需长期随访。

Retroperitoneal inflammatory myofibroblastic tumor

Inflammatory myofibroblastic tumors are rare, and those located retroperitoneally are even rarer. The authors present the case of a 52-year-old male farmer with a lump in the lower abdomen of 2 months in duration that was retroperitoneal in location. It was excised, and histopathologic examination revealed an inflammatory myofibroblastic tumor. The present case is presented by virtue of its rare location.     

An inflammatory myofibroblastic tumor of the nasal dorsum

Inflammatory myofibroblastic tumor of the nose is an uncommon benign proliferative lesion that clinically mimics a neoplastic process. Our case arose in a 4-year-old girl presenting with a mass in the nasal dorsum. The mass was completely excised without any difficulty under general anesthesia. This tumor is a localized and completely benign lesion. Surgical resection is proper management for this condition.     

Abdominal inflammatory myofibroblastic tumor a clinicopathologic study with reappraisal of biologic behavior

Background and Purpose

Inflammatory myofibroblastic tumor (IMT) is a proliferative lesion of controversial nosology and uncertain prognosis. In an attempt to acquire further understanding of pathogenesis and biologic behavior, we surveyed abdominal IMTs managed over the last 12 years at a single institution.

Methods

Intra-abdominal IMTs treated between 1995 and 2007 were reviewed concerning demographic, clinical, and pathologic features as well as therapeutic management and outcome. All specimens were reevaluated by histologic examination and immunohistochemistry.

Results

There were 7 patients (4 males; age range, 28 days to 14 years). Five lesions were located in alimentary tract: 1 gastric presenting with bleeding, 1 hepatic presenting with a thoracic wall mass, 1 pancreatic and 2 colonic presenting with obstructive symptoms. One splenic IMT was found incidentally. The remaining case arose from the adrenal gland and presented with a palpable mass. The gastric and adrenal IMTs had evidence of a previous or concomitant infectious setting. Five lesions were excised. The pancreatic IMT underwent a drainage procedure followed by steroid administration, and the hepatic lesion received antibiotics. Histopathology revealed characteristic findings of IMT. Expression of anaplastic lymphoma kinase was negative in all cases. At a median follow-up of 6 years (range, 3-15), all children were asymptomatic with no recurrences. The hepatic and pancreatic IMT displayed complete and near total regression, respectively.

Conclusion

A benign behavior of abdominal IMTs was observed even in patients not undergoing surgical excision. Although IMT remains a surgical disease, a conservative approach may be reasonable in select cases.     

Inflammatory myofibroblastic tumor of the liver

Inflammatory myofibroblastic tumor is a rare benign entity formerly known as inflammatory pseudotumor. Involvement of the liver is extremely rare. There are controversies about the optimal treatment of this benign entity. Newer reports suggest an association with autoimmune sclerosing pancreatitis and primary sclerosing cholangitis. We present a case of an 18-year-old patient with biliary obstruction from a perihilar mass of the liver requiring hepatic resection. Division of the hepatic bile duct resulted in drainage of yellow, thick, gelatinous material in the presence of benign margins and absence of cholangitis. Histological examination showed a mass with fibroblastic and myofibroblastic cells set in a loose myxoid matrix containing scattered lymphocytes, consistent with an inflammatory myofibroblastic tumor. One-year recovery was uneventful. This report discusses the presentation, diagnosis, and controversies in management of this disease.     

Pulmonary inflammatory myofibroblastic tumor associated with nephrotic syndrome

Inflammatory myofibroblastic tumor (IMT) of the lung is a benign, non-metastasizing tumor with the possibility of local infiltration, recurrence or persistent local growth. This kind of tumor arises due to an unregulated growth of inflammatory cells. To our knowledge, IMT associated with nephrotic syndrome has not yet been recognized. Therefore, we present the case of a 14-year-old girl with lung IMT associated with secondary nephrotic syndrome (NS), which was cured after tumor removal.     

膀胱炎性肌纤维母细胞瘤一例报告并文献复习

目的探讨膀胱炎性肌纤维母细胞瘤的临床、病理、组织化学特性和诊治方法及预后。方法总结1例膀胱炎性肌纤维母细胞瘤患者的临床资料。患者,男,54岁,肉眼血尿10 d入院。盆腔B超及CT增强扫描示膀胱前壁占位性病变。膀胱镜检可见顶壁4 cm×4 cm×5 cm肿物,表面缺血呈暗红色,病理活检疑为膀胱尿路上皮恶性肿瘤。结果行膀胱部分切除术。组织学表现为增生的梭形或长梭形肿瘤细胞囊状分布,间质小血管增生,伴淋巴细胞、嗜酸性粒细胞及浆细胞浸润,诊断为膀胱炎性肌纤维母细胞瘤。免疫组织化学染色结果为瘤细胞平滑肌特异性肌动蛋白（＋）、波形蛋白（＋）、间变性淋巴瘤激酶（＋）。随访6个月,患者无瘤存活。结论膀胱炎性肌纤维母细胞瘤确诊依据病理学检查,应与横纹肌肉瘤、梭形细胞肉瘤等鉴别,治疗以膀胱部分切除或经尿道切除为主。     

肝脏炎性肌纤维母细胞瘤的多层螺旋CT及MRI表现

目的探讨肝脏炎性肌纤维母细胞瘤（HIMT）的多层螺旋CT（MSCT）及MRI影像特点。 方法回顾性分析2015年2月至2017年11月乐山市人民医院经手术病理证实的6例HIMT,术前2例行MSCT平扫,4例行MSCT平扫+增强扫描,4例行MRI平扫+增强扫描,CT未增强者均行MRI平扫+增强扫描,对患者肿瘤的部位、大小、密度/信号、形态、囊变、强化程度和方式进行评估。 结果6例HIMT患者MSCT显示均为稍低密度,MRI信号不均匀;5例动脉期边缘模糊强化,1例无明显强化,6例门脉期及延迟扫描期均有明显强化。 结论MSCT及MRI成像均能够明确显示HIMT的形态学改变、强化程度及方式,MRI多序列成像更能初步判断肿瘤内部的可能构成成分,尤其是病灶内部坏死区在T2WI压脂序列呈低信号对诊断更有重要参考价值。
