Rat renal mesenchymal tumor as an experimental model for human congenital mesoblastic nephroma: II. Comparative pathology.

The morphological features of kidney neoplasms induced by ethylnitrosourea (ENU) with or without prior irradiation were examined with a view to comparing them with human renal tumors of childhood. The rat renal tumors consisted of poorly differentiated, highly mitotic mesenchymal cells frequently attempting to differentiate along fibroblastic and myofibroblastic lineages. Though the host renal tubules were frequently entrapped in these tumors, immature tubules and islands of epithelial cells occasionally were seen to form an integral part of the neoplasms. Rarely, adenomatous areas surrounded by mesenchymal proliferation were observed. None of the tumors had the blastemal component that is the hallmark of nephroblastoma. The rat mesenchymal tumors resembled the human congenital mesoblastic nephroma.

Necrotising arteritis in amoebic colitis.

Massive intestinal haemorrhage rarely occurs in amoebic colitis. We report a case of caecal amoebic ulcer in a 61 year old diabetic male who presented with massive lower intestinal haemorrhage requiring blood transfusion and emergency surgical intervention. Histologically, trophozoites of Entamoeba histolytica were seen invading the wall of the submucosal arteries, causing necrotising arteritis. Rupture of a necrosed artery probably caused massive haemorrhage.

Brown tumor of the hard palate in secondary hyperparathyroidism.

Jaw bones are rarely involved in secondary hyperparathyroidism. We report a case of 13 year old girl who presented with progressive chronic renal failure and secondary hyperparathyroidism. Five months after beginning of hemodialysis, a large brown tumor developed on the hard palate, extending to the maxilla causing difficulty in swallowing and breathing. She died of massive intestinal hemorrhage five months after excision of the mass.

Multiple myeloma presenting as proliferative (crescentic) glomerulonephritis.

Glomerular extracapillary cellular proliferation with crescent formation initially presenting as rapidly progressive glomerulonephritis is a rare clinical manifestation of multiple myeloma. We report here a case of a 58 year old female who initially presented with haematuria, loss of weight and appetite and history of febrile episodes and was diagnosed following renal biopsy as rapidly progressive glomerulonephritis. Haemodialysis was carried out a month later because of uremic symptoms and maintained with monitoring of serum, calcium, phosphate, alkaline phosphatase, albumin and iPTH levels. After 6 months, she complained of bone pains over anterior chest wall which persisted even with low calcium haemodialysis. Serum protein electrophoresis and bone marrow aspiration revealed multiple myeloma. On starting chemotherapy, bone pain subsided but the patient expired within 15 days of therapy.
