Case reports of insulinoma and nesidioblastosis in Ethiopia.

We present history, physical examination, diagnosis and histological findings of one case of insulinoma and another case of nesidioblastosis. Insulinoma is a rare endocrine tumor, which is usually benign, characterized by hypoglycemic symptoms. The first case presented with seizure, which made diagnosis difficult. The second case presented with typical hypoglycemic symptoms. Both cases underwent partial pancrectomy and splenectomy after workup. The histology of the first case was consistent with insulinoma, while the second case was that of nesidioblastosis.
