An approach to reporting of pancreatic specimen
;
Reporting of pancreatic biopsies for the diagnosis
of neoplastic lesions ;
Reporting of ampullary and periampullary biopsies
for the diagnosis of neoplastic lesions ;
Reporting of Pancreaticoduodenectomy (Whipple's
operation) specimen
;
Distal Pancreatectomy is usually carried out for endocrine tumours and
for exocrine neoplasms that arise in the body and tail of the pancreas.
Nesidioblastosis may be found on a partial pancreatectomy specimens taken
for a suspected
Insulinoma , and may be inapparent macroscopically.
Some insulinomas are very small and the entire specimen may need to be embedded
in order to find the tumour.
Microscopic report:
The report should comment on :
-
The tumour type: endocrine, adenocarcinoma, cystadenocarcinoma, cystadenoma ;
-
Perineural and vascular invasion;
-
Extrapancreatic structures involved: spleen, lymph nodes;
-
Completeness of excision.
For endocrine neoplasms the report should also state
the:
-
Pattern of growth: trabecular, moire
silk, packeted, diffuse ;
-
Immunostaining characteristics ;
-
Appearance of islets away from the
tumour : hyperplasia, amyloid deposition.
