To study the sequence of histopathologic changes taking place in the cornual portion of the fallopian tube subsequent to exposure to quinacrine, 252 mg were inserted transcervically in 12 women awaiting hysterectomy for non-malignant conditions of the uterus. All patients who underwent surgery within ten days of insertion were found to have necrosis of the epithelial lining and an acute inflammatory reaction. Later on, the changes observed included progressive absorption of the inflammatory cellular exudate, progressive fibrosis, with partial or almost complete occlusion of the lumen, and failure of regeneration of the epithelial lining. Our results support other studies indicating that quinacrine can effectively produce tubal fibrosis and occlusion.
