Report on Slide Session, British Society for Haematology, 44th Annual Scientific Meeting, Cardiff, 2004

Each year at the Annual Scientific Meeting of the British Society for Haematology Annual Scientific Meeting, there is a morphology session in which two experts discuss the diagnosis, on the basis of a blood film or bone marrow trephine biopsy section provided from six patients. The same slides are provided in advance to other participants in the meeting. The experts receive no information other than that provided to all participants. After a provisional or definitive diagnosis has been made, the case contributors present further details and discuss the final diagnosis. The slide session presented here is in the same order as at the meeting so that readers can arrive at their own conclusions about the diagnosis.
