[Dedifferentiated liposarcoma of spermatic cord: degeneration of lipoma previously resected].

Spermatic cord sarcomas are rare tumours. Dedifferentiated liposarcoma accounts for only 10% of all spermatic cord sarcomas. These are usually large-sized tumours histologically characterised for being well-differentiated liposarcomas with some high grade sarcoma areas. Volume, location, mass homogeneity as well as presence of pelvic and retroperitoneal adenopathies are reported by CT and ultrasound techniques. These are useful for post-treatment follow-up. This paper presents one spermatic cord, dedifferentiated liposarcoma from which lipomas from the same spermatic cord had been previously removed in three occasions. We believe this is a degeneration of the earlier resected lipoma. Management is by extended inguinal radical orchiectomy. Value of adjuvant radio- and chemotherapy is uncertain. Post-surgery local relapses are common, and haematogenous and pelvic nodes metastasis likely. Survival at 5 and 10 years is 75% and 63% respectively.
