case_images: A thoracic CT scan revealed an occupying lesion below the neck of the pancreas (Figure 1A), which on contrast-enhanced CT was seen to be a 7.7 x 6.0 cm lesion in the vicinity of the left aspect of the pancreatic uncinate process, encasing the SMA and some of its branches (Figure 1B).
case_images: The ectopic SPT surrounded the SMA outside the pancreas (A) and no lesion was identified in the pancreas during the operation (B).

case_images: Via the approach of the inferior colon, a large, solid, firm, fixed and highly vascularized tumor was observed behind the root of the mesentery, completely encasing the mesentery (Figures 2A,B).
case_images: Histological examination showing characteristics of SPT: papillary structures (A) and cercariform cells (B): slight nuclear atypia (triangles) and delicate elongation of the cytoplasm (arrows). (hematoxylin-eosin, original magnifications x200[a], x400[b]).

case_images: The tumor specimen measured approximately about 0.8 x 0.6 x 0.3 cm grossly and subsequent histopathology revealed cercariform cells with pseudopapillary formations (Figures 3A,B).
