Lipoma or sarcoma.

Sarcomas are rare malignant mesenchymal tumors, occurring both in the childhood and in adult population. The differential diagnosis of soft tissue lesions includes a wide range of tumors with different clinical manifestation and biological behaviour. Clinical examination of superficial lesions is insufficient and often leads to an underestimation of the extent of the disease. Correct diagnosis and operative technique are key parameters to avoid unnecessary excessive resections in benign tumors, or, on the contrary, non-radical procedures in malignant tumors. Many of the patients are examined late. Unplanned surgical resections represent a major problem in local control of the dis-ease. The goal of this work is to increase the awareness of the medical professionals in the field of soft tissue tumors.
