Solitary Juvenile Polyp Presenting as an Ileo-Ileal Intussusception in an Infant: A Case Report

Abstract

Juvenile polyposis syndrome (JPS) was first described in 1964. It is a rare (approximately one in every 100,000 individuals) autosomal dominant disease that is characterized by the occurrence of several juvenile polyps in the gastrointestinal tract. Juvenile polyp is a specific type of hamartomatous polyp. The term ‘juvenile’ refers to the polyp histology rather than the age of onset of the polyp. An isolated juvenile polyp is not diagnostic of JPS and occurs in approximately 2% of children and adolescents. Here we present a case of a 7 month old baby boy who presented with recurrent vomiting and abdominal pain and on examination revealed RIF mass and tenderness. Clinically, the diagnosis of intussusception was suspected and confirmed on sonographic examination. Exploration of the abdomen revealed ileo-ileal intussusception. Further, Juvenile polyp was identified by the presence of cystically dilated glands lined by cuboidal to columnar epithelium, filled with secretions, abundance of edematous lamina propria with inflammatory cells on histopathological examination. The relevance of this case report lies on the fact that appearance of juvenile polyp in ileum is rare.
