title: Malignant intra-abdominal testis. A case report.
abstract: A case of malignant change within an intra-abdominal testis is reported. The development in a Black man of a malignant testicular lesion with a mixed cellular picture on histological examination, the absence of serum tumour markers in the presence of a seminoma and the presence of local invasive spread--all uncommon features of testicular tumours--in combination make this a rare case. Orchiopexy does not reduce the risk of malignant change and in the postpubertal patient does not influence spermatogenesis. Orchiectomy is therefore advised for all maldescended testes and should be considered mandatory for all intra-abdominal testes.
