Collectively clinical case reports constitute a huge repository of medical experience. This talk will scrutinise their shape, salient features, and the nature of the hindsight from which they are composed, filtered for coherence, and turned into second order accountsof encounters, observations and reasoning about a patient or series of patients. It asks what case reports are good for and what kinds of knowledge they embody.
