Synchronous granular cell tumors of the pancreas and cecum.

Granular cell tumors (GCT) are rare and typically benign. Diagnosis is challenging due to nonspecific imaging characteristics and symptomatology. Herein, we report a combination of pancreatic/cecal GCTs in a 43-year-old man. Contrast enhanced MDCT demonstrated a 1.5 cm well-defined homogeneous intraluminal cecal mass and a 1.6 cm slightly hypervascular pancreatic body mass. On MRI, the pancreatic mass showed increased enhancement on post-gadolinium delayed sequences. Diagnosis was confirmed by excisional pathology (S100 and CD68, PAS-D positive). Radiologists, gastroenterologists, and surgeons should ponder the possibility of GCTs in the differential diagnosis of any small, pancreatic or cecal well-defined tumor.
