[Mesenchymal tumor associated with hypoglycemia and an elevated NSILP (author's transl)]

An unusually located mesenchymal tumor with hypoglycemia is observed. Insulin, cortisol, growth hormone, glucagon levels are within the normals. The glucogenic aminoacids have also been measured, as well as the NSILP which was three times as high as the upper limit of normal values. The various processes which might have brought about the patient's hypoglycemia are discussed.
