Congenital pancreatic lipase deficiency is a rare, monoenzymatic form of exocrine pancreatic failure. All reported patients have presented with similar symptoms and clinical findings, including oily/greasy stools from infancy or early childhood and the absence of discernible pancreatic disease. Failure to thrive has not been observed. Analyses of duodenal contents consistently show a marked decrease of pancreatic lipolytic activity (summary by Figarella et al., 1980). [from
