CD30 and Epstein–Barr virus RNA expression in sclerosing angiomatoid nodular transformation of spleen

Sclerosing angiomatoid nodular transformation (SANT) is a splenic lesion composed of angiomatoid/vascular nodules surrounded by hyalinized/sclerotic stroma, fibroblasts, myofibroblasts, and inflammatory cells. The endothelium within the nodules has a phenotype resembling splenic sinusoids, capillaries, and small veins. Martel et al. (Am J Surg Pathol 28:1268–1279, 2004) suggested that SANT may represent the final pathway of a variety of splenic lesions including inflammatory pseudotumors (IPTs). Epstein–Barr virus (EBV) has a role in the genesis of some splenic IPTs, but its presence in SANT has not been investigated. Six cases of SANT are reported. All were stained for CD31, CD34, CD8, CD68, smooth muscle actin, muscle-specific actin, and CD30 and were tested for EBV by in situ hybridization (EBER). All cases showed angiomatoid nodules with complex expression of CD31, CD34, and CD8, with focal CD68. Expression of CD30 by endothelial cells was also seen. One case had small diffuse areas lacking nodules resembling an IPT and was positive for EBV. The inflammatory cells and the normal spleen were negative for CD30 and EBER. In conclusion, SANT shows upregulation of CD30 with respect to normal spleen. The presence of EBV in the stromal cells of a case supports the notion that a subset of SANT may be related to IPT.

Dysregulation of antioxidant responses in patients diagnosed with concomitant Primary Sclerosing Cholangitis/Inflammatory Bowel Disease

Objective

Primary Sclerosing Cholangitis (PSC) is a chronic cholestatic liver disease that is characterized by severe peri-biliary tract inflammation and fibrosis, elevated oxidative stress and hepatocellular injury. A hallmark of PSC patients is the concurrent diagnosis of Inflammatory Bowel Disease occurring in approximately 70%–80% of PSC patients (PSC/IBD). The objective of this study was to determine the impact of end stage PSC/IBD on cellular antioxidant responses and the formation of protein carbonylation.

肺硬化性血管瘤的CT表现分析

目的：分析肺硬化性血管瘤（PSH）的CT表现,探讨其CT征象.材料与方法：回顾性分析经病理证实12例肺硬化性血管瘤患者的CT影像学资料,所有患者均行CT平扫,其中8例行增强扫描,对病灶的部位、形态、瘤周界面、密度及强化特征等进行观察分析.结果：12例病变中,1例为多发,11例为单发,直径约0.2～7.3cm,平均为2.7cm,呈圆形或类圆形11例,略呈浅分叶状1例,CT平扫密度均匀11例,3例见沙粒状钙化,8例增强扫描,6例见“贴边血管征”,1例见明显不均匀的“花斑样”强化,1例无明显强化.结论：PSH的CT表现有一定的特异性,CT增强检查能够为其诊断提供较多有价值的信息.     

Sclerosing Cholangitis: Clinicopathologic Features,Imaging Spectrum,and Systemic Approach to Differential Diagnosis

Sclerosing cholangitis is a spectrum of chronic progressive cholestatic liver disease characterized by inflammation, fibrosis, and stricture of the bile ducts, which can be classified as primary and secondary sclerosing cholangitis. Primary sclerosing cholangitis is a chronic progressive liver disease of unknown cause. On the other hand, secondary sclerosing cholangitis has identifiable causes that include immunoglobulin G4-related sclerosing disease, recurrent pyogenic cholangitis, ischemic cholangitis, acquired immunodeficiency syndrome-related cholangitis, and eosinophilic cholangitis. In this review, we suggest a systemic approach to the differential diagnosis of sclerosing cholangitis based on the clinical and laboratory findings, as well as the typical imaging features on computed tomography and magnetic resonance (MR) imaging with MR cholangiography. Familiarity with various etiologies of sclerosing cholangitis and awareness of their typical clinical and imaging findings are essential for an accurate diagnosis and appropriate management.     

脾硬化性血管瘤样结节样转化1例

患者女,41岁,主因“左上腹阵发性隐痛1个月,加重1天伴绞痛1h”入院.查体未见明显异常,肿瘤标志物、血常规、肝肾功能、电解质均正常.CT:脾实质前部团块状稍低密度灶,边界不清,密度欠均匀,增强呈向心性强化,动脉期病灶边缘环状强化,门静脉期强化范围稍扩大,延迟期强化范围推进至病灶中央,但中央裂隙样低密度灶始终未见强化.     

药物联合内镜下治疗食管胃底静脉曲张破裂出血56例

目的观察药物联合内镜下治疗食管胃底静脉曲张破裂出血的临床疗效及安全性。方法对56例食管胃底静脉曲张破裂出血患者联合药物及内镜下治疗,单纯食管静脉曲张采用套扎或硬化治疗,但急性出血时首选组织粘合剂注射,对合并的胃底曲张静脉同时行组织粘合剂注射。术后观察不良反应、并发症和近期疗效。结果 53例止血成功,成功率94.64%,1例仍有便血,2例发生脑梗死,考虑组织粘合剂引起的异位栓塞。结论药物联合内镜下治疗食管胃底静脉曲张破裂出血安全、有效,但需警惕异位栓塞的发生。     

Idiopathic Sclerosing Orbital Inflammation with Intranasal Extension

Introduction: To report a case of idiopathic orbital sclerosing inflammation (ISOI) with intranasal extension.

Material and Methods: The patient presented with a 6-month history of epiphora, upper eyelid swelling, ptosis and mild orbital pain. Ophthalmologic examination, CT, MRI and biopsy with surgical debulking were performed.

Results: MRI revealed a homogeneously enhancing diffuse right orbital mass in the inferonasal quadrant of the orbit, which extended to the nasal cavity up to inferior nasal concha, maxillary and ethmoid sinuses. Histological analysis showed dense collagenous tissue with sparse infiltration of mixed inflammatory cells. Inmunohistochemical analysis confirmed polyclonality. The diagnosis of idiopathic sclerosing orbital inflammation was made and 80?mg/day of oral prednisolone was prescribed. At last follow up, one year later, there was no clinical evidence of recurrent orbital disease.

Conclusion: ISOI can present with extraorbital extension. Corticosteroids are a reasonable first-line treatment, until the pathogenesis is better understood.
