The recurrence of viral hepatitis B or C after liver transplantation is almost universal but their clinical courses and outcomes are vary widely. We investigated four cases of rapidly progressive and fatal recurrent viral hepatitis following liver transplantation, which were rapidly progressive and fatal. Case 1 was a 58-year-old male, who developed recurrent viral hepatitisC. Case 2, 3, and 4 were a 59-year-old female, a 42-year-old male, and a 50-year-old male, respectively, who developed recurrent viral hepatitis B. In cases 1 and 2, the histopathological features of the first liver biopsies were prominent ballooning degeneration of the hepatocytes but later biopsies revealed significant lobular activity. Case 3 began with a marked fatty change and mild lobular and porto-periportal activity and progressed to severe lobular activity and septal fibrosis. In case 4, the first liver biopsy revealed minimal lobular activity but the second biopsy revealed severe lobular activity.

Chondrosarcoma of the temporal bone is a rare lesion. Clinically it has been confused with chordoma, glomus jugulare tumor and meningioma, among other conditions, and due to its anatomic location, cranial nerve palsy is frequently observed. We report a case involving a 50-year-old woman with chondrosarcoma of the temporal bone.

Desmoplastic fibroblastoma is a rare but distinctive fibrous benign soft tissue tumor that presents a slowly growing, painless, fibroproliferative mass. Occuring in patients of various ages, it appears hypocellular microscopically, and consists of widely spaced bland spindles or stellar-shaped cells that are embedded in rich wavy collagenous or myxocollagenous stroma. Desmoplastic fibroblastoma was first characterized by Evans in 1995. Thereafter, there were several reports of desmoplastic fibroblastoma that it occured commonly in the upper extremity including regions such as shoulder, upper arm, and lower extremity, followed by the head and neck region. But there was no report of occurrence at the ear. We report our experience of desmoplastic fibroblastoma with histopathologic confirmation: we removed a mass at the mastoid cavity and external auditory canal. We also provide a review of literature related to it.

OBJECTIVE: It was suggested that the cause of microalbuminuria is heterogeneous in NIDDM. However, only a few studies are available that investigated the renal pathology in NIDDM patients with microalbuminuria. This study was undertaken to evaluate renal pathology in Korean NIDDM patients with microalbuminuria. METHODS: Fifty NIDDM patients with microalbuminuria and without retinopathy were undertaken renal biopsy. Renal pathologic findings were classified as follows: group A, near-normal finding; group B, typical diabetic nephropathology; group C, atypical patterns of renal injury (mild glomerular change with disproportionally severe tubulointerstitial lesion, arteriolar hyalinosis or global glomerular sclerosis); group D, non-diabetic renal lesion. RESULTS: Seventeen patients were classified into group A, 19 into group B and 8 into group C. Six patients had non-diabetic renal lesions and they were all confirmed to be IgA nephropathy. Fasting blood sugar and GFR were significantly higher in group B than in group A and group C respectively, and systolic blood pressure was higher in group C than in group A. CONCLUSION: Renal pathology in microalbuminuric NIDDM patients without retinopathy was heterogeneous. This may explain heterogeneous clinical meaning of microalbuminuria in NIDDM.

There are a few reports about coexistence of Henoch-Schonlein purpura (HSP) and a variety of malignancy in adults. The accompanying malignancies, in order of frequency, were hematologic malignancy, lung cancer and prostate cancer. Gastrointestinal tract (GIT) cancer associated with HSP was rarely reported which includes 2 cases of stomach cancer, 1 case of small bowel cancer and 1 case of esophageal cancer. Malignancy is proposed to be a triggering factor in the development of HSP, however pathogenesis of HSP associated with malignancy remains obscure. Here, we report 2 cases of HSP associated with malignancy in GIT. One is an adenocarcinoma of the colon and the other is a stomach adenocarcinoma with signet ring cell component.

We present dincopathologic features of three cases of biopsy-proven pancreas allograft dysfunction in Korea. All patients had advanced insulin-dependent diabetes mellitus (IDDM). Case 1 was a 30-year-old woman who underwent a simultaneous pancreas-kidney transplantation. Urinary infection developed 6 days after the operation, which remitted and reappeared, when urine amylase level was normal. Since the 55th day after the operation, intermittent hematuria has persisted. Cytomegalovirus inclusions were detected on the urinary bladder and grafted duodenal mucosa. The graft was removed due to perforation of the grafted duodenum and panperitonitis. Case 2 was a 27-year-old man undergoing pancreas transplantation alone (PTA). Ten days after the transplatation, the level of 24 urine amylase decreased and the graft was not delineated by 99mTc DTPA scintigraphy. Allograft needle biopsy revealed multiple acinar cell necrosis and mild lymphocytic infiltration which were compatible with mild acute rejection. Case 3 was a 25-year-old man undergoing cadevaric PTA. Three months after the transplantation, graft was removed due to gastric perforation associated with cytomegalovirus and angiodestructive fungal infection. Various causes of pancreas allograft dysfunction can be diagnosed by needle biopsy, thus appropriate biopsy specimen should be taken using improved biopsy technique.
