Malignant tumours of the undescended testis: a report of three cases.
Three cases of testicular malignancies arising in undescended testes were treated in the Department of Surgery, Singapore General Hospital. The patients were all adult Chinese male who presented with tumours arising in unilateral, intra-abdominal undescended testes. Two of the tumours were seminomas while the third was a choriocarcinoma. In all 3 cases, the tumours were large and at an advanced stage at the time of presentation. The treatment in these cases was surgical excision of the primary lesion followed by radiotherapy or chemotherapy. The patient with choriocarcinoma died soon after chemotherapy was initiated while the other two cases are alive, one for over 6 years with no recurrence.
