Drug-induced damage to the gastrointestinal mucosa has been mainly focused on damage in the upper tract. However, increasing evidence suggests that commonly used drugs may also affect the mucosa of the lower gut, and particularly in the colon. The aim of this study was to report that fairly homogeneous colonoscopic findings, correlate with histological evidence of drug-induced mucosal injury. Charts of patients with the “cherry tree” colonoscopic aspect were reviewed to correlate the endoscopic and histological findings for a possible association with the use of drugs. Data from 29 patients (5 men, 24 women, age range 16–76 years) with the “cherry tree” colonoscopic findings were analyzed. Histology revealed an increase in eosinophils in the left colon in 23 patients, pseudomelanosis coli in 3, and microscopic colitis in 3. The findings were associated with proton pump inhibitors in 19 (65.5 %), non-steroidal anti-inflammatory drugs or statins (3 cases each), and other drugs [4 cases, including estroprogestinics (1), antidepressants (2), and thyroxin (1)]. The “cherry tree” colonoscopic appearance suggests drug-induced colonic damage. Awareness of this association may prevent unnecessary, expensive and time-consuming procedures.
