RESUMO
UNLABELLED: 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 <2-3âcm 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 17.5âcm×10âcm×9.5âcm. We present the first - giant - malignant paraganglioma. Moreover, it is the first case report of a paraganglioma in the testis. LEARNING POINTS: 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 17.5âcm×10âcm×9.5âcm.
RESUMO
INTRODUCTION: The intraductal papillary mucinous neoplasms (IPMNs) are increasingly diagnosed entities with high potential of malignancy and significant recurrence rates. PRESENTATION OF CASE: In this case report a rare mixed IPMN with full invasion of the pancreatic ducts was identified. DISCUSSION: Difficulties in determining the grade of pancreatic duct involvement make the surgical management tough. CONCLUSION: In multifocal IPMNs the management of the patients is even more challenging. In this case the patient was treated successfully with total pancreatectomy.
