Patient: This condition: a hard mass next to the brachial artery on the inner side of the right upper arm has rapidly increased in size within a month and a half, without pain or itching or sliding, with no change in skin color. There is pressure pain. On 2011.11.4, the mass was surgically removed at Tangshan Fengrun County Hospital, pathological examination was done and it was said to be malignant. Re-pathological examination was done for extraosseous Ewing’s sarcoma/peripheral primitive neuroectodermal tumor. It said to do EWS-FLI-1 fusion gene test to confirm and to go to a specialist hospital if necessary. Pathological examination report: CD99(+), Vimentin(+), CD34(-), CD31(-), S-100(-), SMA(-), Desmin(-), NSE(-), EMA(-), Ki-67(index 3%). Please see if this is the type of tumor and give a treatment suggestion. Thank you, doctor! Hospital: It is recommended to bring postoperative pathology slides or wax blocks to our pathology department for consultation. Patient: Post-operative pathology slides or wax blocks were taken to your hospital on November 14 for immunohistochemistry and other pathology tests. The results will be available in 3 days. Is it possible to see you if the test result is this kind of tumor? Patient: Hello doctor, I called the pathology center today and was told that my mother’s pathology needs additional items and the results will not be available until next Monday or so.

Patient: Hello, doctor: My mother, Li Shaozhi, returned to Tangshan in December 2011 for 6 weeks of enhanced radiotherapy after her expanded surgery for synovial sarcoma, and her condition was fine after radiotherapy. On May 21, she underwent the first review at Tangshan Workers’ Hospital. The review items and results have been uploaded. 1. CT scan of the chest: the upper lobe of the left lung showed localized fibrous streak shadow and small nodule shadow, the other lung lobes showed regular and clear texture distribution, the hilum was not large, the trachea and main bronchus were unobstructed, the mediastinum was not displaced, the trachea and large blood vessels in the period were normal in shape and size, the gap was clear, no abnormal mass and nodule shadow was seen, the esophagus, diaphragm and pleura were not abnormal. No fluid shadows were seen in the chest cavity. Calcified spots were seen in the left mammary gland. Multiple hypodense foci in the liver are shown. Impression: focal pulmonary fibrosis and small nodular shadow in the upper lobe of the left lung, calcified point in the left mammary gland, and multiple hypodense foci in the liver. 2, abdominal ultrasound, thyroid ultrasound: examination: thyroid scan: bilateral lobe full, uneven echogenic masses can be seen in both lobes, the largest (right) 0.4X0.3CM (left) 0.7X0.5CM, clear borders, regular, liquid dark areas and parenchymal echogenicity can be seen in its periphery, color shows blood flow signal. The liver was normal in size and shape, with smooth peritoneum and heterogeneous parenchymal echogenicity. A liquid dark area with a diameter of about 0.7 CM was seen in the right lobe, with clear and regular borders and an envelope, and no dilatation of the intrahepatic bile ducts was seen in the posterior field. The gallbladder was normal in size, with smooth walls, good bile transmission, and no dilatation of the common bile duct. The pancreas and spleen were not abnormal. The right upper arm was scanned: no significant abnormal mass echogenicity was seen. The examination suggested: multiple substantial occupations in the bilateral lobes of the thyroid gland, small intrahepatic cysts, and no abnormalities in the right upper arm.
