Apple-core lesion of the colon: a case report.

INTRODUCTION: The appearance of the apple-core lesion of the colon can be caused by several diseases. CASE PRESENTATION: A male patient was referred to the surgical clinic with melaena and weight loss. Clinical examination and investigations confirmed an apple-core lesion of the colon. He underwent surgery, but unfortunately, died of a chest infection two weeks after the operation. CONCLUSION: This case shows the use of computed tomography in demonstrating the primary cause of iron deficiency anaemia, and at the same time, staging the disease for loco-regional metastasis.
