RT Journal Article SR Electronic T1 Non-allergic benign infantile proctocolitis: a neglected nosographic entity JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e244918 DO 10.1136/bcr-2021-244918 VO 14 IS 10 A1 Gelsomino, Mariannita A1 Sinatti, Dario A1 Miceli Sopo, Stefano YR 2021 UL http://casereports.bmj.com/content/14/10/e244918.abstract AB The presence of rectal bleeding in the first months of life is very often diagnosed as food protein-induced allergic proctocolitis (FPIAP). The symptoms typically start in infancy, and most cases resolve by age 12 months. Infants with FPIAP usually present bloody stools mixed with mucus, with or without reduced stool consistency. Most affected infants are generally healthy-appearing. We used the story of an infant with rectal bleeding as a reminder that there is also the possibility of a form of benign non-allergic proctocolitis that is not usually included in the differential diagnosis. In the absence of warning signs and in case of infant well-being, it should be the first clinical entity to suspect. Therefore, we suggest we should wait at least 2 months before starting to eliminate cow milk or other foods from the diet.
