Malignant spinal cord compression secondary to testicular seminoma at the time of initial presentation and at relapse while on surveillance.

We report cases of 2 pure seminoma patients who developed metastatic spinal cord compressions. One patient was diagnosed at age 33 years with stage 1 seminoma and, after undergoing an orchidectomy, chose to be followed on a surveillance protocol. He was lost to follow-up and presented again 22 months later with back pain, leg weakness and sensory loss when his disease recurred as a spinal cord compression. He was treated with urgent surgical decompression and subsequent standard chemotherapy. More than 2 years posttreatment, he is disease-free with normal neurologic function in his lower extremities. The second patient presented at age 44 years with back pain and rapid loss of leg strength and sensation. Investigations revealed a malignant cord compression with lymphatic and vertebral body metastases. On physical examination, the patient was found to have a 6-cm left testicular mass. He was treated with emergency radiotherapy to the region of his cord compression followed by a left inguinal orchidectomy. Pathology confirmed a pure classic seminoma. Postoperatively, he received standard chemotherapy and eventually regained neurologic function in his legs. Although it is rare for malignant spinal cord compression to occur in seminoma patients-either as the initial presentation of disease or as a site of disease recurrence in stage 1 patients on surveillance-it is crucial to consider seminoma as a possible etiology in young men diagnosed with malignant spinal cord compression because timely contemporary treatments for seminoma will cure most of these patients and offer them excellent functional recovery.
