Apart from limited small series and some case reports, international literature on flat bone sarcoma is exiguous and not much is known about the oncological outcome Aim of work: Reviewing clinicopathological features and surgical management of cases with primary malignant scapular tumors at NCI from January 2009 to December 2019. Patients and methods: This was a retrospective descriptive analysis involving 25 patients with primary malignant scapular tumors who were presented at National Cancer Institute (NCI), Cairo University (CU) over a period of 10 years from January 2009 to December2019 to discuss different clinicopathological CHARacteristics and surgical managements. Results: The Mean age of our patients was 33.4years old ranging from 9 to 86 year, males are 14 patients (56%) while only 11 patients (44%) are female, in our study and the results were chondrosarcoma in 14 patients (56.0), EWING/PNET in 7 patients (28.0%), Osteosarcoma in 2 patients (8.0%), spindle cell sarcoma in 1 patient (4.0) and Aneurysmal bone cyst in 1 patient (4.0%).Also there were 13 patients (52.0%) treated with type IIA resection , 6 patients (24%) treated with type IIIB resection and only 1 patient (4.0%) treated with type IVB resection.in addition , there were another 5 patients (20.0%) had no surgical intervention due to very poor general condition and metastatic nature. Overall survival at 6 months was 92% and was 88%, 75.4% and 65.4% at first year, 3rd year and 5 th year respectively Conclusion: Primary malignant scapular tumor is usually rare, early diagnosis is very important, as surgical excision with wide negative margin (limb sparing surgery) is the main line of treatment in most of cases and to decrease recurrence rate, otherwise palliative treatment and forequarter amputation may be indicated specialized by Ibrahim Adel Mohammed Shaker ; Supervised Prof.Dr.Magdy Ibrahim Elsherbiny , Prof.Dr.Ihab Samy Fayek , Prof.Dr.Ibrahim Abdelrahman Ibrahim Thesis (M.Sc.)-Cairo University,2022.
