[Spermatic cord liposarcoma. Association with prostate cancer. Report of a case and review of literature].

Spermatic Cord Liposarcoma are uncommon soft tissue neoplasm. Association with others tumors is so exceptional. We describe and relation between liposarcoma and prostate cancer in a 66 years old patient who had a left paratesticular tumor with low speed growth and 12 cm of length; nodule in prostate gland was detected. Ecography demostrate an hipoecoic tumor in the spermatic cord; Prostate Specific Antigen (PSA) was 1276 ng./ml. and bone gammagraphy reported metastatic lesions. We made an radical orquiectomy and pathological diagnosis including inmunohistoquimical process was sclerosing dedifferenciated liposarcoma. We discuss clinical and pathologic behaviour of this lesions and diagnosis and treatment options.
