Tumori del retroperitoneo: Trattamento chirurgico di un voluminoso liposarcoma di 25 kg

Retroperitoneal sarcomas are rare malignancies which represent only 1% of all human neoplasms. Liposarcoma is the most common histologic subtype with an incidence, in written reported cases, between 25% and 65%. These tumors can reach large dimensions and often, at the moment of diagnosis, may result surgically unresecteable. Here is an illustration of the clinical case and the surgical treatment of a 55 year old man affected by a voluminous retroperitoneal liposarcoma. The extension of the neoplasia and the involvement of adjacent organs (right kidney, stomach, ascending colon) initially addressed the patient toward various chemiotherapeutic reductive treatments, without success. The quick growth of the neoformation and the appearance of a bowel obstruction state have imposed the surgical excision of the mass. The intervention, made difficult by the tenacious adhesions and infiltration of the neoplasia with the adjacent organs, resulted on the excision of a voluminous neoplasia of 25 kg.
