Materials and methods. The retrospective study included a group of 103 patients diagnosed in our department during 2010 and 2017. Considering the high healing rate of benign tumors, only the group of neoplastic patients (45 cases) was involved in the survival rate estimation, assessing tumor characteristics and individual comorbidities.

There have been significant variations in mortality between the different histological subtypes (liposarcoma vs. synovial sarcoma). Local recurrences were shown in 18 cases of liposarcoma in the first 2 years after the surgical excision, with an increased aggressiveness of this neoplasm in men over 50 years. 12 cases developed distant metastasis, and, until the end of the study, 7 deaths were reported in 3 cases involving associated comorbidities. Conclusions. The five-year survival is inversely proportional to the extent of the tumor and the local invasion, as well as to the age of the patient. It is difficult to appreciate an overall survival rate in the context of a heterogeneous group of tumors so it must be evaluated for every histological subtype taking into account the patient’s particularities.</p></abstract>
