    A 79 year old man presented with occult gastrointestinal bleeds and anaemia for two years. He had received 40 units of blood over a period of one year, following which he had a subtotal colectomy as no definite cause of the bleeding was apparent. Macroscopically the colon appeared unremarkable. Light microscopy showed prominent lymphocytic venulitis in the proximal portion, gradually merging into lymphocytic and collagenous colitis distally.
