The book "Treatment of Liposarcoma of the Extremities" offers a comprehensive analysis of liposarcoma, a group of malignant tumors that occur in the extremities. It addresses the various behaviors of these tumors, which range from benign to aggressive forms that have a high risk of recurrence and metastasis. Given that liposarcoma is the most common soft tissue tumor in the extremities, the necessity of a clearly defined, multidisciplinary treatment approach is emphasized. The authors, Antonio Valcárcel Díaz, Francisco Javier Carrillo Piñero, and Jose Pablo Puertas García-Sandoval, have written this work to develop a protocol for the diagnosis and treatment of this neoplasm. They highlight the importance of correctly applying diagnostic techniques to avoid delays in the diagnosis and treatment process that can lead to a poorer prognosis.
