Tuberculous pancreatic abscess: a rare condition mimicking carcinoma.

We report a rare case of obstructive jaundice caused by a tuberculous abscess in the head of pancreas, mimicking carcinoma. The case was successfully treated by pylorus-preserving proximal pancreatoduodenectomy and antituberculous drugs.

Electron microscopic study of liver tissue from 30 thalassemic patients.

Electron microscopic study of liver tissue from 30 thal patients in advanced stages has been described. In all cases, regardless of the type of hemoglobin, electron microscopic observations gave identical results. Significant findings are ferroacidophilic bodies, ferroacidophilic degeneration of hepatocytes, interhepatocyte collagen, hemosiderin and ferritin, paracrystalline accumulations of ferritin molecules, and liver cell ballooning.

Histochemical study of liver tissue from thalassemic patients.

The livers of 30 cases of advanced thalassemia were studied pathologically. Severe degrees of hemosiderosis and fibrosis were found in liver cells and Kupffer cells in most cases. Various histochemical stains have been used to determine the characteristics of FAB and to grade degrees of iron deposit and fibrosis.
