A 'giant' paraganglioma in the testis.
Until now, less than ten cases of extra-adrenal chromaffin cell tumors have been reported to be localized to the spermatic cord area. All published studies report benign tumors with a diameter <2-3 cm and no invasion of the testis. In this article, we present one case of a giant malignant paraganglioma in the testis of a patient who had initially been operated for a giant mass in the scrotum. The mass developed in approximately 4 months. This is the first study reporting the following findings: i) paraganglioma was found exclusively in the testis, invading the testicle and not the spermatic cord, ii) it was malignant with lung metastasis, and iii) its size was 17.5 cm×10 cm×9.5 cm. We present the first - giant - malignant paraganglioma. Moreover, it is the first case report of a paraganglioma in the testis.


CONCLUSIONS
This is the first study reporting the following findings:Paraganglioma found exclusively in the testis, invading the testicle and not the spermatic cord.It is malignant with lung metastasis.It is of the size 17.5 cm×10 cm×9.5 cm.
