AbstractAbstract PDF
Mycophenolate mofetil (MMF)-related colitis is one of the common causes of afebrile diarrhea in transplant patients. Pathologic diagnosis of MMF-related colitis is difficult because microscopic findings of MMF effects resemble those of graft-versus-host disease, inflammatory bowel disease and ischemic colitis. However, if diagnosed, MMF-induced colitis can be markedly improved by discontinuing the drug. A 70-year-old man having a history of transplantation presented with a one month history of afebrile diarrhea. Colonoscopy revealed patchy erosions. The colonoscopic biopsy specimen showed not only crypt disarray with degenerated crypts and scattered epithelial cell apoptosis, but also stromal inflammatory cell infiltration. A review of his medical records showed that he had been taking immunosuppressive drugs including MMF since his heart transplantation 6 years prior. The histologic findings of colonic mucosa were consistent with MMF-related colitis. After discontinuing MMF, the diarrhea quickly resolved and has not recurred for 10 months.

AbstractAbstract PDF
Renal cell carcinoma (RCC) is notorious for its high metastatic potential, and 30% of RCC patients present with metastatic disease at the initial presentation and 50% of them will develop metastasis or recurrence after radical surgery.
In an attempt to identify the best predictive marker(s) for metastasis in patients with clear cell RCCs (CRCCs), we examined the expression patterns of 7 metastasis/prognosis-related markers by constructing a tissue microarray including primary CRCC specimens from 30 metastatic and 60 nonmetastatic CRCCs. The markers we studied were Ki-67, MUC1, CD44s, PTEN, gelsolin, CA9 and p53.
The expressions of Ki-67, PTEN, CD44s, gelsolin and p53 were increased, whereas those of MUC1 and CA9 were decreased in the metastatic CRCCs compared with the non-metastatic CRCCs. The receiver operating characteristic curve-area under the curve (AUC) value of Ki-67 was 0.671, which was the highest among the 7 markers. The optimal cut-off value, sensitivity and specificity of the Ki-67 expression were 1.67%, 86.7% and 41.7%, respectively.
These results demonstrate that the Ki-67 expression was increased in metastatic CRCCs, and it had the highest predictive value among the 7 markers. This suggests that Ki-67 could be an excellent predictive marker for metastasis in CRCC patients.

AbstractAbstract PDF
We report on a case of angiomatoid fibrous histiocytoma located deep in subcutaneous tissue of the left shoulder in an 11-year-old boy. An ovoid firm mass was slowly increasing in size for 5 months without any pain or tenderness. The tumor was grossly multicystic, with dense fibrous capsule and it measured 7.5 x 7.5 x 4.0 cm. The locules contained hemorrhagic fluid, and the inner surface was purplish brown and trabecular. The septal solid areas were cellular, and they consisted of histiocytoid spindle cells that were arranged in a storiform or fascicular pattern. The tumor cells showed immuno-positivity for CD99, CD68 and desmin. These findings were compatible with angiomatoid fibrous histiocytoma of an uncommon location.

AbstractAbstract PDF
Idiopathic portal hypertension (IPH) is a rare clinicopathologic entity that shows clinical evidences of portal hypertension with no pathologic features of cirrhosis.
The clinical and pathologic features of 8 cases with IPH were analyzed via the medical records along with the biopsy or resected liver specimens.
Six patients were male and two were female. The chief complaints were sudden variceal bleeding in seven patients and abdominal pain in one patient. Six patients were treated with varix ligation and one was treated with splenectomy after the failure of bleeding control. One patient underwent a liver transplantation due to severe symptoms of portal hypertension. The prognosis of all the patients was excellent. Microscopically, the portal tracts were variably fibrotic, and the portal veins in them were sclerotic, obliterated or dilated in 7 cases; pathologic abnormalities were absent in 1 case. Cirrhosis was absent in all cases, while septal fibrosis was present in one resected liver.
IPH is a minor cause of portal hypertension. However, a liver biopsy to show the subtle portal vascular changes and fibrosis in patients who have the clinical symptoms of portal hypertension is important for making the diagnosis of IPH.
