Angiographic findings in one giant cell carcinoma, one cystadenocarcinoma, one poorly vascularized mucinous cystadenocarcinoma, as well as in two avascular (gastrin- and glucagon-producing) islet-cell tumors of the pancreas are described. Two hypervascularized islet-cell tumors are presented for comparison and a case of tumorous chronic pancreatitis in a child is reported because ot its rarity. The aggressiveness of the giant cell carcinoma of the pancreas was demonstrated by its expansive growth. In the case of cystadenocarcinoma angiography revealed the tumor with hepatic metastases not diagnosed at explorative laparotomy. The relative hypovascularity in the case of mucinous cystadenocarcinoma was unusual. Both avascular islet-cell tumors simulated a pancreatic pseudocyst and the final diagnosis was made only by immunoassay. Chronic pancreatitis in a child presented with marked hypervascularization.

Studies on diabetes mellitus in tropical zones indicate that its traditional link with overnutrition depends not only on the economic level, but also on some ethnic, social and cultural factors. At present, we insist on the unexpected relationship between diabetes mellitus and undernutrition either in some major infantile forms (described in India and Nigeria) with calcareous pancreatitis, or some less severe forms observed in Africa. This tropical diabetes mellitus occurs in some patients with normal weight or inferior to normal; it is not very ketogenic, responding to glucagon stimulation, and seems more frequent in the chronic malnutrition areas. So, it is tempting to utilize diabetes mellitus as an indicator of nutritional disorder or of dietary toxic factors. However, we ought to consider it within a multifactor surroundings associating genetic determinism and the other factors of tropical aggressiveness.
