Paratesticular sarcomas: two cases with different evolutions.

Abstract

Paratesticular sarcomas are rare and account for less than 1% of all adult sarcomas. Intrascrotal tumours can be testicular or paratesticular, paratesticular tumours being rarer (7-10%). Only 30% of paratesticular tumours are malignant and 90% of these are sarcomas. Histological subtypes include leiomyosarcoma, rhabdomyosarcoma, liposarcoma and undifferentiated high-grade pleomorphic sarcoma. Recurrence is frequent in this type of tumour and can occur years from initial diagnosis. These reports show two cases of paratesticular sarcoma with very distinct evolutions. The first case concerns a patient who presented with low-grade leiomyosarcoma with two local recurrences treated with surgery, and distance recurrence with cutaneous, subcutaneous, pulmonary and hepatic metastasis 30 years after surgery of the primary tumour. The second case reports of a patient who presented with high-grade myxoid liposarcoma with local and distance recurrence 3 years after surgery of the primary tumour, which progressed after chemotherapy; the patient died 7 months after diagnosis of recurrence.
