Primary granulocytic sarcoma of the urinary bladder: case report and review of the literature

We report a case of granulocytic sarcoma of the urinary bladder, with no evidence of hematologic involvement. The patient was initially misdiagnosed and was treated with chemotherapy for transitional carcinoma grade 3. Despite this treatment, the clinical features of the patient progressed, and a repeated biopsy yielded the correct diagnosis. Three cases of granulocytic sarcoma of the urinary bladder have been reported in published studies, with only one of these primary. To our knowledge, ours is the second case of granulocytic sarcoma of the urinary bladder presenting with urologic symptoms but without hematologic findings.     

原发性膀胱神经鞘瘤1例报告并文献复习

目的 探讨原发于膀胱的神经鞘瘤和恶性周围神经鞘瘤在组织病理学、临床表现、治疗和预后上的特点,确立两者的鉴别诊断思路.方法 回顾1例原发于膀胱的神经鞘瘤的临床诊疗过程,结合有关膀胱神经鞘瘤及膀胱恶性周围神经鞘瘤的文献资料进行分析.结果 在组织病理和免疫组化方面,原发于膀胱的神经鞘瘤和恶性周围神经鞘瘤有明显差异.结论 原发于膀胱的神经鞘瘤临床极其少见,易与膀胱常见肿瘤混淆,造成误诊,免疫组化为重要的确诊依据.膀胱恶性周围神经鞘瘤应以高度恶性的软组织肉瘤进行处理.临床上应重视两种疾病的鉴别,以正确地指导临床诊疗.     

Primary gastric synovial sarcoma: A case report and literature review

IntroductionSynovial sarcoma (SS) is a mesenchymal neoplasm that is characterized by its unique histological pattern and is most commonly found near the joints of the extremity. Stomach involvement is very rare. This work aimed to present the case of a patient with gastric SS. We also conducted a review of 39 gastric SS cases reported in the literature.Presentation of caseHere we report a case of primary gastric synovial sarcoma in a 32-year-old male patient revealed by gastric reflux. Partial gastrectomy was performed showing a 35 mm lesion with a high spindle cell component. Immunohistochemistry revealed 18q11.2 translocation expression in most of the cells asserting a diagnosis of SS. No local or distant recurrence occurred at 8 months post-operative follow-up.DiscussionThe majority of SS occurs in the extremities and is most often associated with tendons in the large articulations of young adults. Gastric SS are very scarce and a molecular biology approach to detect the SYT-SSX fusion gene is required for conclusive diagnosis. We carried out a clinical review of the 40 cases of primary gastric SS, including our case. They all underwent an excisional surgery, most of them by partial gastectomy or wedge resection. Recurrences were rare and early when they occurred.ConclusionGastric SS is a very uncommon neoplasia although it is henceforth a described entity. Immunohistochemical detection of a pathognomonic translocation is needed to make the diagnosis of SS. Best therapeutic approach for these tumors remains surgical resection with no specific excisional technique recommended.     

原发性肾滑膜肉瘤一例报告并文献复习

目的探讨原发性肾滑膜肉瘤的临床特点及诊治方法。 方法回顾性分析我院原发性肾滑膜肉瘤1例的临床资料,并对国内外相关文献进行回顾。 结果患者接受根治性左肾切除术,术后病理回报为原发性肾滑膜肉瘤。 结论原发性肾滑膜肉瘤非常罕见,无特异性临床特点及影像表现,诊断主要依靠病理及免疫组化,SYT-SSX融合基因有提示作用,主要治疗方案为手术,化疗对生存率的影响还需进一步研究。     

肾原发性滑膜肉瘤1例报告及文献复习

目的提高对肾原发性滑膜肉瘤的诊治水平。方法回顾性分析1例晚期肾原发性滑膜肉瘤的诊治经过,并报告采用索拉非尼治疗其肺转移灶的经验。结果本例临床和影像学表现无特异性,患肾切除术后常规病理检查误诊为肾母细胞瘤,经免疫组化检查及联合病理会诊,确诊为肾原发性滑膜肉瘤(梭形细胞型)。采用依托泊苷、异环磷酰胺、顺铂化疗联合索拉非尼靶向药物治疗其肺部转移灶,获得部分缓解,但索拉非尼单药治疗及免疫治疗效果不佳。疾病控制期为6个月,生存期11个月。结论肾原发性滑膜肉瘤诊断困难,对肿瘤标本进行免疫组化或分子学分析方可确诊。一旦发生转移,预后不佳,联合采用以高剂量异环磷酰胺为基础的化疗和索拉非尼靶向药物治疗可能获得一定疗效。

Primary spindle cell sarcoma of heart: case report and review of literature

Primary spindle cell sarcoma of the heart is a rare malignant tumor of the heart. A 65-year-old woman was admitted under our care with complaints of shortness of breath. Echocardiogram showed pedunculated mass in the left atrium. Cardiac magnetic resonance imaging done elsewhere had confirmed a left atrial tumor. No further investigations were considered with a diagnosis of left atrial myxoma. She underwent total excision of the tumor: mitral valve involvement necessitated a repair all of which was done under cardiopulmonary bypass. Histopathology showed a primary spindle cell sarcoma. In view of histology, chemotherapy was planned and initiated. A month after surgery, she presented again with a recurrence.
