Renal transplant recipients who received immunosuporessive agent are in high risk of development Kaposi's sarcoma. In Korea a few report of Kaposi's sarcoma has been pubilshed but any report of intrathoracic Kaposi's sarcoma provedn by open lung biopsy has not been pulbilshed until now. We report a case of intrathoracic Kaposi's sarcoma developed in a 25 year old Korean man, who had been operated renal transplantation due to end stage renal disease and received cyclosporine and prednisolone as immunosuppessive agent, without any other organ involvment and was proven by open lung biopsy. Although discontinuation of immunosuppressive agent, temporary symptomatic and radilolgic improvement were observed, he died 11 days later after open lung biopsy because of intractable resiratory failure.

In 2021, a new chapter on the general management of glomerulonephritis (GN) was added to the Kidney Disease: Improving Global Outcomes (KDIGO). It emphasizes the importance of early general management of GN for improving long-term kidney outcomes and prognosis. The chapter introduces the management of glomerular diseases in 18 subchapters. Here, kidney biopsy for the diagnosis and evaluation of kidney function and the management of complications, such as hypertension, infection, and thrombosis, are presented. Moreover, the adverse effects of glucocorticoids and immunosuppressive therapy, which are commonly used drugs for glomerular disease, are mentioned, and a guideline for drug selection is presented. Each subtheme focused on items reflecting the interpretation of the "practice points" of the expert working group are introduced. In this review of the general treatment for GN in the KDIGO guidelines, excluding pregnancy and reproductive health, we focused on and compared various references pertaining to pediatric GN management.

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially fatal condition characterized by skin rash, fever, eosinophilia, and multiorgan involvement. Various drugs may be associated with this syndrome including carbamazepine, allopurinol, and sulfasalazine. Renal involvement in DRESS syndrome most commonly presents as acute kidney injury due to interstitial nephritis. An 11-year-old boy was referred to the Children's Hospital of Pusan National University because of persistent fever, rash, abdominal distension, generalized edema, lymphadenopathy, and eosinophilia. He previously received vancomycin and ceftriaxone for 10 days at another hospital. He developed acute kidney injury with nephrotic range proteinuria and hypocomplementemia. A subsequent renal biopsy indicated the presence of acute tubular necrosis (ATN) and late exudative phase of postinfectious glomerulonephritis (PIGN). Systemic symptoms and renal function improved with corticosteroid therapy after the discontinuation of vancomycin. Here, we describe a biopsy-proven case of severe ATN that manifested as a part of vancomycin-induced DRESS syndrome with coincident PIGN. It is important for clinicians to be aware of this syndrome due to its severity and potentially fatal nature.

Minimal change nephrotic syndrome is characterized by proteinuria, hypoproteinemia, edema, and hyperlipidemia. Children with onset of nephrotic syndrome between the age of 1 and 8 year are likely to have steroid response to minimal chage disease, but we experienced one case of minimal change disease which failed to respond to steroid therapy at beginning and subsequently developed acute renal failure. It was seen in a 5 year-old male child that presented with edema and gross hematuria. Peritoneal dialysis was performed for acute renal failure for 11 days. Patient was completely recorvered from acute renal failure and renal biopsy was done at 27th day after onset of disease which revealed typical picture of minimal change disease complicated by acute tubular necrosis. We beleive this case is very unusual and it may be the first case in the literature in terms of pediatric cases.

Purpose: To classify the results of renal biopsy in pediatric patients and to compare pathological findings with clinical features. Methods: This study included data of 318 children who underwent renal biopsy at our hospital between December 1987 and November 2014. Biopsy specimens were examined histopathologically using light, immunofluorescence, and electron microscopy. Results: Asymptomatic urinary abnormalities was the most common clinical diagnosis (35.9%), followed by nephrotic syndrome (29.3%), and acute glomerulonephritis (18.0%). Glomerular disease was identified in 98.1% of the renal biopsy specimens. The most common primary cause of glomerulonephritis was IgA nephropathy, with gross hematuria in 61.9% of the patients, hypertension in 14.2%, proteinuria >1.0 gm/24-hr in 33.3%, and impaired renal function in 3.6% patients. Conclusion: The most common clinical diagnosis was asymptomatic urinary abnormalities, with primary glomerular disease being the most common renal biopsy finding, and IgA nephropathy the most common histopathological lesion. This study provides a 27-year overview of pediatric renal disease at our center and underlines the importance of renal biopsy for accurate diagnosis and proper management.

Fabry disease is an X-linked lysosomal storage disorder caused by a deficiency of the enzyme ${\alpha}-galactosidase$ A, resulting in the accumulation of glycosphingolipids within the lysosomes of various cell types. It has a wide spectrum of clinical phenotypes, and renal failure is a serious complication. Fabry disease is confirmed either by measurement of ${\alpha}-galactosidase$ A activity or by genetic testing for GLA mutations. Renal biopsy findings on light microscopy, specifically enlarged podocytes with foamy cytoplasm, and osmiophilic inclusion bodies in the cytoplasm in all types of renal cells on electron microscopy, are characteristic of this disease. The predominant differential diagnosis is iatrogenic phospholipidosis in association with certain drugs that can cause cellular injuries indistinguishable from Fabry disease. Here, we report the case of a 10-year-old boy with microscopic hematuria who underwent a renal biopsy that showed morphological findings consistent with Fabry disease, although the patient had neither a GLA mutation nor a history of drug consumption. Six years later, spontaneous regression of this renal pathology was observed in a second renal biopsy examination.

Background: Kidney injury molecule-1 (KIM-1) is known as a good ancillary marker of acute kidney injury (AKI) and its expression has also been observed in acute rejection and chronic graft dysfunction. We tested usefulness of KIM-1 as an indicator of acute and chronic renal graft injury by correlating KIM-1 expression with renal graft function and histology. Methods: A total of 133 zero-time biopsies and 42 follow-up biopsies obtained within 1 year posttransplantation were selected. Renal tubular KIM-1 staining was graded semiquantitatively from 0 to 3 and the extent of staining was expressed as the ratio of KIM-1 positive/CD10 positive proximal tubules using Image J program. Results: KIM-1 was positive in 39.8% of zero-time biopsies. KIM-1 positive cases were predominantly male and had received grafts from donors with older age, deceased donors, and poor renal function at the time of donation, compared with KIM-1 negative cases. KIM-1 expression showed correlation with delayed graft function and acute tubular necrosis. In comparison of KIM-1 expression between stable grafts (n=23) and grafts with dysfunction (n=19) at the time of repeated biopsy, the intensity/extent of KIM-1 staining and renal histology at zero-time did not differ significantly between the two groups. Histologically, KIM-1 expression was significantly increased with both acute and chronic changes of glomeruli, tubules and interstitium, peritubular capillaritis, and arteriolar hyalinosis. Conclusions: KIM-1 can be used as an ancillary marker of AKI and a nonspecific indicator of acute inflammation and tubulointerstitial fibrosis. However, KIM-1 expression at zero-time is not suitable for prediction of long-term graft dysfunction.
