Combined membranous nephropathy and crescentic glomerulonephritis with concurrent anti-glomerular basement membrane antibody and myeloperoxidase-specific anti-neutrophil cytoplasmic antibody.

We report a case of a 71-year-old man with rapidly progressive nephritic syndrome and dual positivity for anti-glomerular basement membrane antibody and myeloperoxidase-specific anti-neutrophil cytoplasmic antibody. Renal biopsy revealed crescentic, mainly cellular, glomerulonephritis with granulomatous lesions, and advanced membranous changes. Membranous nephropathy had apparently existed for an extended period before the development of crescentic glomerulonephritis.

De novo acute hepatitis B in myeloperoxidase-specific anti-neutrophil cytoplasmic autoantibody-related microscopic polyangiitis treated with corticosteroids.

An 82-year-old female was referred to our hospital because of low-grade fever, anemia, and rapidly progressive nephritic syndrome. Her laboratory data showed mild proteinuria, mild renal failure, and the presence of myeloperoxidase-specific anti-neutrophil cytoplasmic autoantibody. A skin biopsy specimen taken from the erythematous purpura revealed neutrophilic infiltration around the blood vessels with fibrinoid changes in the vessel walls.

[A case of sigmoid colon cancer in a patient undergoing hemodialysis treated by tegafur/uracil/folinate].

The patient was a 59-year-old man who had undergone hemodialysis because of chronic renal failure. The patient was diagnosed as colonic perforation due to stricture of sigmoid colon cancer, and sigmoidectomy was performed. Since colonic perforation and imperfect lymphnode dissection might increase the risk of recurrence, the patient underwent 6 courses of tegafur/uracil/folinate(UFT/LV)chemotherapy.

Pulmonary blastoma within bronchioloalveolar cell carcinoma.

Pulmonary blastoma is a rare tumour of the lung composed of epithelial and mesenchymal elements that morphologically resemble the embryonal structure of the lung. The authors report a 79-year-old man who was diagnosed with a pulmonary blastoma within bronchioloalveolar cell carcinoma. Macroscopic, histopathological and immunohistochemical findings suggested that the pulmonary blastoma was closely associated with the bronchioloalveolar cell carcinoma.

Pulmonary cryptococcosis within a pulmonary carcinoma-review of reported cases.

An asymptomatic 71-year-old man was admitted for evaluation of a pulmonary tumor. Chest computed tomography revealed a cavitary tumor in the apical segment of the right lung. Histopathological examination of the resected lung revealed pulmonary cryptococcosis within a papillary adenocarcinoma.

Delayed onset acute renal failure associated with Amanita pseudoporphyria Hongo ingestion.

A 66-year-old man with diabetes developed acute renal failure after ingestion of Amanita pseudoporphyria Hongo. Laboratory data showed acute nonoliguric renal failure. A renal biopsy showed acute tubular necrosis with glomerular minor abnormalities.
