 We reviewed the histologic features of non-steroidal anti-inflammatory drug (NSAID) -induced colitis, using biopsy specimens from 16 cases. Clinically, they were divided into three types ; ulcerative-type (10 cases), colitis-type (3 cases) and ileitis-type (3 cases) . In addition to them, a surgical case of ileal diaphragm disease was also evaluated. Histologically, they were classified as non-specific enteritis-type (12 cases), ischemic enteritis-type (1 case), hemorrhagic enteritis-type (2 cases) and eosinophilic enteritis-type (1 case) . Diaphragm disease was considered to be a special form of non-specific enteritis-type, histologically (or ulcerative-type clinically).

 In spite of mild inflammation and mild epithelial damage, mitotic figures and apoptotic bodies are occasionally seen in non-specific enteritis-type. It is suggested that apoptosis plays an important role in ulcer formation of NSAID-induced enteritis. Every type essentially had a different histologic features, which suggests different mechanism in each of them. However, they shared some features which indicates that the mechanisms of each type might be complicated by overlapping.
