[Well differentiated paratesticular liposarcoma in adults]. / Liposarcome paratesticulaire bien différencié chez l'adulte.

ABSTRACT

The authors report a case of well differentiated paratesticular liposarcoma in a 41-year-old patient. This is a rare tumour (about one hundred cases have been reported in the literature), which essentially arises from the spermatic cord. Clinical and radiological signs are nonspecific and the diagnosis is generally based on histological examination of the operative specimen. Due to the histological similarities, all specimens of benign lipoma must be examined for the presence of well differentiated liposarcoma. Treatment consists of transinguinal radical orchidectomy, sometimes with resection of adjacent structures. The prognosis is generally better than that of other paratesticular sarcomas. Adjuvant radiotherapy may be indicated in locally advanced masses or in the case of incomplete resection.
