纵隔黏液样脂肪肉瘤1例报告并文献复习

<正>黏液样脂肪肉瘤(Myxoid liposarcoma,MLPS)是脂肪肉瘤(Liposarcoma)中的一种亚型,占20%～30%,好发于下肢,以大腿多见,而发生在纵隔者较为罕见,好发年龄为30～50岁^[1-2]。目前,国内外发表的关于纵隔黏液性脂肪肉瘤的文献均为个案报道,其临床症状和影像学特征均缺乏特异性,临床诊断准确率较差。因此,为了加深对纵隔黏液样脂肪肉瘤的认识,提高诊断治疗水平,现报告我科收治的1例患者情况,并复习国内外1984年10月至2016年8月间相关的个案报道文献12篇,对其临床表现、诊断、治疗进行分析和总结。     

Sarcoma of the maxillary sinus in a patient with malignant melanoma: Report of a case

Low-grade fibromyxoid sarcoma: clinicopathologic case report with review of the literature

Low-grade fibromyxoid sarcoma is a rare, benign-appearing soft tissue neoplasm with an aggressive clinical course characterized by multiple local recurrences over several years, with ultimate spread to lung and occasionally to bone. Thus far, a total of 24 cases of low-grade fibromyxoid sarcoma have been reported in the literature. The authors present an additional case that grossly and microscopically emphasizes a pronounced lobular pattern of contrasting areas of cellularity showing high proliferative activity, as demonstrated by a proliferation marker, Ki 67 with MIB-1, and hypocellular areas with prominent myxoid component and abundant collagen fibrils. There was predominance of delicate capillary-sized stromal vessels with collagenized walls in both cellular and myxoid areas. The unusual features in this case were osseous metaplasia, prominent intranuclear pseudoinclusions, DNA tetraploidy, and membrane-bound intracytoplasmic fat vacuoles. The immunoprofile and cytologic and ultrastructural features are described. After the excision of the tumor, the patient was treated with radiotherapy without chemotherapy. The patient has been observed for 26 months and is alive without the evidence of disease. The postoperative follow-up with axial computed tomography at 24 months showed no evidence of disease, except postsurgical fibrotic changes.     

脾组织细胞肉瘤一例并文献复习

目的:提高对脾组织细胞肉瘤诊断及治疗的认识。方法:回顾性分析天津中医药大学第一附属医院2020年7月收治的1例脾组织细胞肉瘤患者的临床资料,并复习国内外相关文献。结果:该患者经组织病理及免疫组织化学检查确诊为脾组织细胞肉瘤,经甲泼尼龙联合环孢素治疗无效,予全脾切除,后行VECD及CHOP方案化疗,术后5个月随访,病情稳定,复查骨髓穿刺结果显示未见组织细胞肉瘤浸润,获得血液学缓解。结论:脾组织细胞肉瘤属于高度恶性肿瘤,起病隐匿,发病机制不明确,临床表现及影像学检查缺乏特异性,诊断依靠病理活组织检查及免疫组织化学检查,需与其他淋巴造血组织恶性肿瘤鉴别。目前尚无最佳治疗方案,多数患者预后不良。

Frontal sinus carcinoma: A case report and review of the literature

A rare case of frontal sinus carcinoma is reported. The patient developed early recurrence following surgery, and was managed by accelerated hyperfractionated radiation therapy and concurrent cisplatinum-based systemic chemotherapy. The patient has remained disease-free for 30 months following the end of treatment.     

Ewing sarcoma of the hand: literature review and a case report of nonsurgical management

A case of a 12-year-old girl with Ewing sarcoma of the third metacarpal bone is described. Following an incisional biopsy, radiation therapy and adjuvant chemotherapy were given. The girl is now 34 months postdiagnosis and 25 months off therapy in sustained complete remission and functionally normal right hand. Of the seven previously published cases only two are long-term survivors (one had disarticulation, and the other resection of the fourth and fifth rays).     

Verrucous carcinoma of the frontal sinus: A case report and review of the literature

Carcinoma of the frontal sinus is rare. Treatment is controversial, and prognosis is poor, The etiology is unknown, although some risk factors for other paranasal sinus carcinomas have been identified. A 70-year-old male presented with proptosis and x-ray findings consistent with a mucocele of the frontal sinus. At operation the patient was felt to have a cholesteatoma. Pathologic diagnosis was verrucous carcinoma of the frontal sinus. The case is discussed and the literature is reviewed.     

Co-existence of metastatic uterine sarcoma and orbital sarcoidosis: A case report and literature review

A 77-year old lady with previously treated endometrial sarcoma presented with progressive left upper lid mechanical ptosis secondary to superior orbital mass. An orbital biopsy confirmed the diagnosis of orbital sarcoidosis. Further systemic work up revealed suspicious pulmonary nodules which were found to be endometrial sarcoma metastases rather than systemic sarcoidosis on image guided biopsy. She was treated with 20 months of chemotherapy for metastatic sarcoma. The ptosis completely resolved, however, pulmonary metastases progressed despite chemotherapy. The co- existence of malignancy with sarcoidosis should be considered in all cases of new onset sarcoidosis. Biopsy of suspicious lesions, close observation and multidisciplinary team management is advocated for these patients.
