Colorectal infantile myofibromatosis: an unusual cause of rectal prolapse and sigmoid colo-colonic intussusception: a case report

BACKGROUND Infantile myofibromatosis is a rare mesenchymal disorder of infancy that can extensively involve the viscera including the gastrointestinal tract. CASE PRESENTATION In this report, an exceptional case of infantile myofibromatosis is described in which rectal prolapse and sigmoid colo-colonic intussusception were the initial presentations of colorectal involvement in a 2-month-old premature female infant. CONCLUSION To the best of our knowledge, this is the first case reporting rectal prolapse and the second case documenting intussusception secondary to gastrointestinal involvement by infantile myofibromatosis.
