[Recurrent retroperitoneal liposarcoma, diagnostic and therapeutic problems].
Retroperitoneal liposarcomes are characterised by their tendency to recurrence, Eight cases are related, from which no one get out of this rule. Late diagnosis is due to their silent growth and poor symptomatology. Ancillary procedures, particularly computerised tomography, and histological examination, allow to confirm diagnosis. The main treatment is surgery, it must be as aggressive as possible, it allows to confirm histologically the nature of the tumor. Postoperative radiotherapy is helpful and chemotherapy can be associated, if it seems that complete excision has not been possible or if metastasis are detected. Histologically, these sarcomes seem to derive from a pluripotential mesenchymatous cell, it explains their polymorphic differentiation. A clinical prognosis, based on histology, seems to be illusive.
