If one is to be guided correctly by the accounts of or, rather, the lack of accounts of pancreatitis in the leading textbooks on pediatrics; from personal communications from twelve eminent pediatricians of the United States and from several of our leading pathologists, none of whom admit having ever encountered a case, and from a rather careful survey of the literature, acute pancreatitis in children is a very rare condition. It seems expedient, therefore, that the present case be placed on record. In 1889, Fitz read his memorable paper on acute pancreatitis before the New York Pathological Society, and classified acute pancreatitis as being either hemorrhagic, suppurative or gangrenous. In recent years, surgeons and pathologists have added a fourth type of acute pancreatitis: the acute nonsuppurative. These cases of simple nonsuppurative pancreatitis are comparatively mild in nature. The patients recover, and such cases are rarely, if ever, seen at necropsy.
