Dataset Information

Primary synovial sarcoma of the lung successfully resected under temporary bypass.

ABSTRACT: A 48-year old man presented with chest pain and haemoptysis. Chest computed tomography showed a 60-mm mass in the left upper lobe of the lung, adjacent to the distal aortic arch. Bronchoscopic cytology revealed the presence of malignant cells and, in the absence of evidence of distant metastasis, a thoracotomy was performed. Although the tumour was firmly adherent to the distal aortic arch, under temporary bypass from the left subclavian artery to the descending aorta, it was successfully resected en bloc with the section of the aorta attached to it. The tumour was diagnosed as a primary synovial sarcoma of the lung on the basis of histopathological findings and fluorescent chromogenic in situ hybridization, showing SS18 gene rearrangement.

Project description:BackgroundPrimary gastric synovial sarcoma is extremely rare, only 44 cases have been reported so far, and there have been no reports of laparoscopic endoscopic cooperative surgery for this condition.Case presentationA 45-year-old male patient presented with gastric pain. Esophagogastroduodenoscopy was performed that led to the identification of an 8-mm submucosal tumor in the anterior wall of the antrum, and a kit-negative gastrointestinal stromal tumor was suspected following biopsy. On endoscopic ultrasonography, the boundary of the tumor, mainly composed of the second layer, was depicted as a slightly unclear low-echo region, and a pointless no echo region was scattered inside. A boring biopsy revealed synovial sarcoma. Positron emission tomography did not reveal fluorodeoxyglucose (18F-FDG) accumulation in the stomach or other organs. Thus, the patient was diagnosed with a primary gastric synovial sarcoma, and laparoscopic endoscopic cooperative surgery was performed. The tumor of the antrum could not be confirmed laparoscopically from the serosa, and under intraoperative endoscopy, it had delle on the mucosal surface, which was removed by a method that does not involve releasing the gastric wall. Immunohistochemistry showed that the spindle cells were positive for EMA, BCL-2 protein, TLE-1, and SS18-SSX fusion-specific antibodies but negative for KIT and DOG-1. The final pathological diagnosis was synovial sarcoma of the stomach. The postoperative course was good, and the patient was discharged from the hospital on the 11th postoperative day.ConclusionResection with laparoscopic endoscopic cooperative surgery (LECS), which has not been reported before, was effective for small synovial sarcomas that could not be confirmed laparoscopically. With the combination of laparoscopic and endoscopic approaches to neoplasia with a non-exposure technique (CLEAN-NET) procedure, it was possible to excise the tumor with the minimum excision range of the gastric serosa without opening the stomach.
