RT Journal Article SR Electronic T1 Lymphocytic venulitis: an unusual association with microscopic colitis. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 303 OP 304 DO 10.1136/jcp.52.4.303 VO 52 IS 4 A1 Arora, D S A1 Mahmood, T A1 Wyatt, J I YR 1999 UL http://jcp.bmj.com/content/52/4/303.abstract AB 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.
