Rectosigmoid lithobezoar in a eight-year-old.

Bezoars are rare foreign bodies in the gastrointestinal tract. They may be composed of hair (trichobezoars), vegetable matter (phytobezoars), milk curds (lactobezoars) and, very rarely, stones (lithobezoars). Colonic lithobezoars are very rare findings in children. We report an eight-year-old boy with a giant rectosigmoid lithobezoar, who presented with history of recurrent constipation and pica for five years. Four hundred and seventy two (472) pieces of asphalt stones ware manually evacuated via the anus.
