Hepatic lesions of vascular origin in multicentric Castleman's disease, plasma cell type: report of one case with peliosis hepatis and another with perisinusoidal fibrosis and nodular regenerative hyperplasia.

We report two cases of multicentric Castleman's disease, plasma cell type, associated with three different liver lesions. Peliosis hepatis was observed in one case and perisinusoidal fibrosis with nodular regenerative hyperplasia in the other. These observations give some evidence that Castleman's disease, per se, may be involved in these three presumably interrelated liver vascular lesions.

Human hydatidosis in Niger.

Thirty-two cases of hydatidosis were collected in two Nigerian hospitals during a 5-year period; 81% of these had extra-hepatic localizations. Human hydatidosis has been considered as exceptional in West Africa but seems to be an underestimated disease in Niger. Studies in slaughtered animals from Niger show a high prevalence of hydatidosis in camels while no infection was found among sheep.
