Pathological findings of the secondary resected specimen of the pancreas body and tail lesions. a, b Two tumors were identified at the pancreas a body and b tail. a A white solid mass (5 mm in diameter) with well-defined margins adjacent to the main pancreatic duct (MPD) was observed in the pancreas body (circle). b A white solid mass (5 mm in diameter) with ill-defined margins farther away from the MPD was also observed in the pancreas tail (circle); this mass had not been detected in the preoperative images. Neither of these tumors exhibited luminal mucin secretion. c, d Microscopic findings of the resected specimen (c pancreas body lesion, d pancreas tail lesion). c A solid nodular tumor with a dilated MPD was observed (original magnification, × 20). d The tumor with ill-defined margins was farther away from the MPD (original magnification, × 20)
