An abdominal CT scan showed an additional left para-aortic tumor with enhanced density ( Figure 1 ). The 131I-mataiodobenzyl-guanidine (MIBG) scintigraphy results showed two radio-uptake enhancing regions in the left abdomen and pelvis after 48 and 72 h ( Figure 1E ).
Macroscopic examination and immunochemistry results of the tumors. (A) Macroscopic examination of para-aortic PGL. (B) Macroscopic examination of para-vesical PGL. (C) HE staining of tumors. (D-F) Immunohistochemistry results of the tumors. Syn (+), CgA (+), S-100 (+), and the Ki-67 positive index was 1%. Scale bar = 50 mum.

Figure 2A ); and the other nodular tumor showed a similar morphology ( Figure 2B ). Further immunochemistry results reported Syn (+), CgA (+), S-100 (+), GATA3 (+), PCK (-), HMB45 (-), and MART-1 (-), and the Ki-67 positive index was 1% ( Figures 2C-F ). Combined with the morphological features, the tumors were considered as PGLs.
