"Leiomyosarcoma is a rare type of smooth muscle cell tumor, with an incidence of 7-10% compared to other types of sarcomas. It develops primarily in the retroperitoneal cavity, the genital tract and extremities. Leiomyosarcoma can also affect the bone, either as a primary tumor or as metastasis. Primary osseus leiomyosarcoma is a rare finding in patients with radiologically identified osteolytic lesions having an incidence of <1% of total primary bone tumors.Due to its low incidence patients with primary osseous leiomyosarcoma are never diagnosed before immunohistochemical analysis and case management is difficult because of the lack of specific indications pertaining to primary osseus leiomyosarcoma. Data on age specific incidence is scarce but there seems to be a tendency towards a higher incidence with advanced age. The purpose of this work is to discuss the complete management of primary osseus leiomyosarcomas based on interdisciplinary medical teams’ indications in a Romanian hospital setting"

"Background: Rotator cuff tendinopathy is most often described as a continuum between the normal cuff and rotator cuff tears with calcific tendinitis having its place along this continuum. Although many studies have focused on the role of magnetic resonance imagining (MRI) in diagnosing the extent of rotator cuff tears and their associated findings with good interobserver reliability, the same cannot be stated about MRI tendinopathy findings. Because of this discrepancy in diagnostic reliability, tendinopathy tends to be overtreated with injections when associated with symptoms, thus potentially increasing the risk of calcific tendinitis and progression toward rotator cuff tears. This study aims to assess whether diagnosing shoulder MRI tendinopathy patterns through dichotomization can accelerate clinical progress toward consensus. Methods: This study is a large retrospective cohort of 184 patients that underwent a 1.5T shoulder MRI for shoulder pain. Inclusion criteria were acromioclavicular arthrosis diagnosed in patients of any age. Exclusion criteria were partial or complete rotator cuff tears. Tendinopathy was considered the dependent variable and registered as a dichotomous variable while acromioclavicular joint arthrosis together with gender was categorical and age was the continuous variable. An attempt was made to generate a clinically significant binary logistic regression to assess the odds ratio of diagnosing tendinopathy based on age, gender, and acromioclavicular joint arthrosis status. Results: An overwhelming proportion of patients was positive for tendinopathy findings (95.11%). 64.12% of patients were within the active age group with patients within the 50-59 group being diagnosed the most with rotator cuff tendinopathy. Conclusions: Due to the high variability of MRI findings that can be considered positive for rotator cuff tendinopathy, an overwhelming skew toward a positive diagnosis was observed, thus dichotomizing tendinopathy diagnosis is not appropriate for clinically relevant conclusion-making "
