Background

We summarize our experience in the pathological diagnosis of late complications of liver transplantation (LT) to better understand the causes of late allograft dysfunction in a population mostly composed of patients with hepatitis B virus (HBV) infection.

Methods

We reviewed 361 post-transplant liver biopsies from 174 patients who underwent LT and first presented with liver function abnormalities 3 months post-procedure. The underlying diseases included HBV-associated liver disease (77%), toxic or alcoholic liver disease (10.3%), hepatitis C virus (HCV)-associated liver disease (8.6%), primary biliary cirrhosis (1.2%), primary sclerosing cholangitis (1.2%), and metabolic disease (1.7%).

Results

The three most common late complications were acute rejection (32.5%), recurrent disease (19.1%), and biliary complication (17.1%). Patients who underwent LT for HBV infection or for drug- or alcohol-related liver disease had a lower incidence of recurring disease than those who underwent transplantation for HCV infection. During post-transplantation months 3-12, acute rejection was the most common cause of allograft dysfunction and recurring disease was the leading cause for allograft dysfunction (p=0.039). The two primary causes of late allograft dysfunction have overlapping histological features, although acute rejection more frequently showed bile duct damage and vascular endothelialitis than recurring HBV infection, and recurring HBV infection had more frequent lobular activity and piecemeal necrosis.

Conclusions

The causes of late liver allograft dysfunction are closely associated with the original liver diseases and the period after LT. Careful attention is required for differential diagnosis between acute rejection and recurrent HBV.

Abstract PDF: The incidence of severe hepatitis A virus (HAV) infection has been increasing. However, clinicopathologic features of severe HAV infection that lead to liver transplantation (LT) have not been reported in Korea. We retrieved 16 LT cases with HAV infection during the last 3 years at Asan Medical Center, Seoul, Korea. Fifteen cases progressed to hepatic encephalopathy. Thirteen cases survived with or without complications, and three patients died of sepsis. The explanted liver showed massive or zonal necrosis with moderate to severe cholestasis. The zonal distribution of necrosis was frequently associated with endothelialitis of portal and/or central veins. Degenerative changes of hepatocytes were various in degree and distribution. Viral inclusions were suspected in two cases. Although HAV infection is usually confirmed by serological tests, significant venulitis of central and/or portal veins and viral inclusions, which are rarely observed, can suggest an HAV infection as a cause of massive hepatic necrosis of unknown mechanism.

Abstract PDF

Ovarian primary malignant melanoma is very uncommon with only 44 reported cases in the literature. A 71-year-old woman with an ovarian mass and multiple nodules in the liver presented to our hospital. She was treated with bilateral salpingo-oophorectomy, and malignant melanoma was found in the mature cystic teratoma of the ovary. Malignant melanoma cells were also found in the ascitic fluid. She died 5 months later. Here we report a very uncommon case of malignant melanoma arising in an ovarian mature cystic teratoma with a review of the literature.

Abstract PDF

Desmoplastic small round cell tumor (DSRCT) is a rare, aggressive neoplasm that preferentially involves the abdominal and pelvic cavities in relatively young males. We present a rare case of DSRCT arising in the ovary of a 16-year-old girl. During surgery, a 15 cm-sized huge mass was noted in the right ovary and wide spreading of the tumor was identified in the left ovary, uterine wall, and omentum and bowel wall. Histological investigation showed nests of small round cells with round nuclei and scanty eosinophilic cytoplasm accompanied with dense desmoplastic stroma. The immunohistochemistry showed that the tumor coexpressed epithelial, mesenchymal, and neuronal markers. The tumor cells ultrastructurally showed poorly developed cell junctions and occasionally showed intracytoplasmic aggregates of intermediate filaments. Molecular analysis of the tumor revealed chromosomal translocation t(11:22)(p13;q12) associated with the EWS-WT1 fusion protein. DSRCT should be included in the differential diagnosis of ovarian neoplasms in young patients.

Abstract PDF: BACKGROUND
Glomerular epithelial cell protein-1 (GLEPP1) and WT-1 expressed in mature visceral glomerular epithelial cell (VGEC) is required for maintenance of the mature status of VGEC. Nephrin protein is located at the filtration slit and regarded as a molecular component of the slit diaphragm. Alterations of these proteins in proteinuric diseases are not clearly defined.
METHODS
We investigated the expression of GLEPP1, WT-1 and nephrin in 28 renal biopsies diagnosed with minimal change nephropathy (n=10), focal glomerulosclerosis (n=10) and membranous nephritis (n=8) by immunohistochemical staining. Normal control biopsies were obtained from six nephrectomy specimens.
RESULTS
The patients consisted of 15 males and 13 females. The mean age was 40.7 years. Nephrotic range proteinuria (> or =3.5 g/day) was noted in 15 (54%) patients. GLEPP1 and nephrin expression were significantly decreased in patients as compared with those of the controls (p<0.05). The mean number of WT-1 expressing cells per glomerulus was also significantly decreased in patients as compared with those of the controls (p<0.05). However, there was no significant difference in the number of WT-1 expressing cells among the disease groups.
CONCLUSIONS
These results suggest that the loss of biological markers of mature VGEC may play an important role in the pathogenesis of proteinuria.

Abstract PDF: Primary ovarian myxoid tumor such as myxoma, myxoid liposarcoma and myxoid leiomyosarcoma is extremely rare neoplasm. We experienced a case of unusual myxoid tumor of the ovary in a 25 year-old woman. She was admitted for an incidentally found ovarian mass during antenatal check. Radiologic studies revealed a 5.5x5 cm-sized solid mass in left ovary and she was undertaken left oophorectomy. Grossly, the round ovarian mass was measuring 8x6x5 cm, and the cut surface was predominantly solid with myxoid appearance. Microscopically, the tumor was surrounded by thick collagenous capsule and had moderate cellularity and rich vascularity. The tumor cells were stellate-shaped with abundant extracellular myxoid material without atypia. We initially thought this lesion as myxoma, but the cellularity was too high as an ordinary myxoma. Myxoid liposarcoma could also be considered as the differential diagnosis, however there was no convincing lipoblast. So, we diagnosed that tumor as myxoma with uncertain malignant potential.

Abstract PDF: Central core disease is a rare autosomal dominantly inherited non-progressive congenital myopathy, which is pathologically characterized by the formation of a "core". We report a 28-year-old female with non-progressive muscle weakness, who had a hypotonic posture at birth. The developmental milestones were delayed with her first walking at 18 months of age. She could not run or walk a long distance and weight-bearing tasks were almost impossible. None of her family members showed motor symptoms. An investigation of the electromyography and nerve conduction velocity showed non-specific results. A gastrocnemius muscle biopsy revealed central cores in approximately 70% of myofibers with a type 1 myofiber predominance and deranged sarcolemmal structures. To the best of our knowledge, this is the fifth report of central core disease in the Korean literature.
