Colonic malacoplakia: unusual association with ulcerative colitis.
A 44 year old Chinese female with malacoplakia of the colon associated with ulcerative colitis was presented. The patient showed typical histological, electron microscopic and X-ray micro-analysis findings of malacoplakia. The malacoplakia gradually disappeared after discontinuation of high-dose systemic steroid prescribed by private practitioner for the ulcerative colitis. A review of the 26 previously reported cases of malacoplakia of the colon is also included. Coupled with the clinical events of this patient, it appears that malacoplakia is likely to be secondary to immunosuppression, due to drugs, malignant or debilitating diseases.
