Malignant paraganglioma of testis and spermatic cord: a case report

To date, extra-adrenal chromaffin cell tumors in spermatic cord and testis areas are still rarely reported. In this case report, we presented one case of a malignant paraganglioma in the testis and spermatic cord of a patient who had initially been admitted to hospital for recurrent headaches and paroxysmal palpitation. This is the first case report of a paraganglioma in the testis and spermatic cord with multiple metastases. Firstly, the paraganglioma was found exclusively in the testis and spermatic cord, invading the testicle and the spermatic cord; Secondly, it was malignant with lymph node metastasis around the abdominal aorta, right inguinal and right external iliac; Thirdly, It has the ability to secrete high amounts of catecholamines. By combining this case with previous studies of others, we further discussed the clinical characteristics, diagnosis and treatment of the disease.
