Occurrence of paratesticular ganglioneuroma 18 years after concurrent adrenal ganglioneuroma and papillary thyroid carcinoma - A case report

Abstract

Background: Ganglioneuromas (GNs) are composed of mature ganglion cells and Schwann cells with a fibrous stroma; GNs are most often observed in children and young adults. The majority of non-cranial GNs are located in the retroperitoneum and posterior mediastinum. Other reported rare sites include the adrenal gland, small intestine, colon and urinary bladder. However, para-testicular GNs are even more rare. Case presentation: Herein, we report the case of a patient with concurrent adrenal GN and thyroid papillary carcinoma who developed paratesticular GN eighteen years later. Conclusions: We conclude that there is an association among papillary thyroid carcinoma, GN and MEN2 syndromes. This case report may provide important information for the proposed association. However, further studies are required.
