- BACKGROUND
We wanted to find an adjunctive marker(s) in renal allograft biopsies for predicting acute cellular rejection (ACR), and so the expression patterns of immune-related molecules were compared between ACR, borderline ACR and non-ACR cases.
METHODS
The expression patterns of Fas ligand (FasL), HLA-DR, granzyme B, caspase-3, CD56, interferon stimulated growth factor-3 (ISGF-3), and CD53 were assessed via immunohistochemical study in 75 allograft biopsies from patients with ACR (n=19), borderline ACR (n=22), and non-ACR (n=34).
RESULTS
Compared to those of the non-ACR group, the ACR group revealed an elevated number of FasL positive interstitial inflammatory cells, HLA-DR positive tubular inflammatory cells, cytoplasmic caspase-3 positive tubular epithelial cells, granzyme B positive interstitial mononuclear inflammatory cells and CD53 positive interstitial inflammatory cells. The expression patterns of the borderline ACR group were similar to those of non-ACR group, except for the intensity of FasL in the tubular epithelial cells.
CONCLUSIONS
Immunohistochemical investigations of the adjunctive markers FasL, HLA-DR, granzyme B, caspase-3 and CD56 can be useful for making the diagnosis of ACR.

Abstract
PDF
- We describe here a case of traumatic neuroma that developed in the pancreas head as a rare complication of pancreatic surgery for pseudocyst. A 50-year-old man presented with septic shock. The patient was a heavy drinker with history of operation for pancreatic pseudocyst 28 years ago. On the radiologic examinations, a poorly defined mass-like lesion was found in the uncinate process of pancreas, and it had features of chronic pancreatitis and a stricture of the distal common bile duct. Whipple's operation was performed due to the diagnosis of suspected pancreas head cancer. The pancreas revealed an ill-demarcated 4 cm sized firm mass with grayish white fibrotic cut surface in the head portion.
On the microscopic examination, the mass was composed of haphazard proliferations of nerve fascicles in a fibrocollagenous matrix and this case was diagnosed as traumatic neuroma. Although traumatic neruoma is a rare cause of a pancreatic mass, it should be included as a differential diagnosis of pancreatic mass in patients with a history of pancreatic surgery.

Abstract
PDF
- Mixed ductal-endocrine carcinoma of the pancreas is composed of ductal and endocrine carcinoma components and each component makes up a significant proportion in the primary tumor as well as in the tumor of metastatic sites. Mixed ductal-endocrine pancreatic carcinoma is exceptionally rare and, to our knowledge, only five cases have been reported in the literature. Recently we experienced a case of mixed ductal-endocrine pancreatic carcinoma with regional lymph node and hepatic metastases in a 63-year-old woman. Here, we report a case of mixed ductal-endocrine pancreatic carcinoma with a review of the literature.

Abstract
PDF
- Posttransplant lymphoproliferative disorder (PTLD) is a proliferation of B-cells associated with Epstein-Barr virus (EBV) infection as a complication of immunosuppression, especially by FK506. We investigated four cases of PTLD which developed either in allografts or in other organs.
Case
1 was a 38-year-old woman, who developed monomorphic PTLD in a kidney 7 years and 7 months after renal transplantation. Case 2 was a 37-year-old man, who developed monomorphic PTLD in the right submandibular lymph node 4 months after liver transplantation. Case 3 was a 60-year-old man, who developed monomorphic PTLD in the liver 8 months after liver transplantation. Case 4 was a 2-year-old female child, who developed polymorphic PTLD in the colon, liver, and mesenteric lymph node 10 months after liver transplantation. FK506 was administered to case 4. EBV was identified in the tissues of all cases by immunohistochemistry and/or in situ hybridization.
