This specimen is from a young female who presented with intermittent abdominal pain and diarrhea. Imaging studies showed a retroperitoneal mass at the L1 vertebral level. The excised tumor was well-circumscribed with a fibrous capsule and a fleshy, grayish-white cut surface. Histologic features were typical for a ganglioneuroma. Diarrheal symptoms have been linked to the synthesis of vasoactive intestinal peptide synthesized by the tumor cells. Case courtesy of: Dr. Sanjay D. Deshmukh, Professor of Pathology, Smt.
