Abstract
- Anthracosis is a very common disease of the bronchus, while anthracosis of the gastrointestinal tract is extremely rare. Only a few cases of anthracosis of the esophagus have been reported and no cases of anthracosis of the terminal ileum are known, except one patient in Korea who was described as having melanosis ilei. A black pigmented lesion was detected in the terminal ileum on colonoscopic examination of a 51-year-old woman. Histological examination revealed a pigmented lesion beneath the mucosal epithelial layer and lymphoid follicular hyperplasia. The lesion consisted of an aggregation of histiocytes containing abundant tiny black pigments. She has taken oral charcoal for 7 years. We diagnosed anthracosis of the terminal ileum caused by oral charcoal and report a case of charcoal-induced anthracosis of the terminal ileum.
