Clinicalopathological evaluation of soft tissue myxofibrosarcoma

Purpose: The aim of this study is to evaluate the relationship between the clinical course of these tumors by emphasizing the epidemiological data as well as the pathological features of different myxofibrosarcoma cases. Materials and Methods: 22 cases of myxofibrosarcoma were included in the single center study. Age, gender, tumor location, size, histopathological features as well as treatment modalities and clinical follow-up of the cases were also evaluated. Additional immunohistochemical studies were applied for the differential diagnosis in pathological evaluation. Results: The mean age of the patients was 54 years old and there is no sex predilection. The extremities are the most common location. Deep located myxofibrosarcoma were highly aggressive unlike superficial counterparts. The grade given as a result of pathological examination is closely related to the clinical course. Since the mean recurrence period is 16 months, long term follow up is required. Recurrence is present in all metastatic cases. Death from the disease occurred only in those with a higher grade. Conclusion: Myxofibrosarcomas are rarely seen but diagnostically challenging. Accurate diagnosis is essential to differentiate myxofibrosarcoma from other pleomorphic sarcomas, and to manage the treatment of patients since it may mimic even reactive lesions by histopathologically. Superficial and low grade myxofibrosarcoma of present study showed excellent prognosis and it has been presented as a contribution to the literature that these patients may have a good prognosis with correct diagnosis and treatment.
