A 3-year-old boy presented with constipation and perianal lesions resembling condyloma latum. The results of a biopsy of the perianal lesions confirmed the diagnosis of Langerhans cell histiocytosis (LCH). Although uncommon, LCH may involve the perianal region. In patients with functional constipation associated with perianal lesions that do not respond to conventional treatment, LCH should be part of the differential diagnosis. A simple biopsy of the external lesion and histologic examination of the mass are essential for diagnosis.

Gastrointestinal tract (GIT) involvement in Langerhans cell histiocytosis (LCH) is not commonly described. We present two children presenting with GIT involvement with LCH, one successfully treated on standard protocol and other being treated on a protocol for relapsed disease. A review of literature showed almost 95% children were less than 2 years of age and 62% were females. Vomiting, abdominal pain, constipation, intractable diarrhea, malabsorption, bloody stools, protein-losing enteropathy, and even intestinal perforation are some of the reported symptoms. More than 50% patients died within 18 months from diagnosis.
