Differential diagnosesDifferential diagnoses'' are different medical disorders which may cause the same symptoms.  When a doctor asks what the differential diagnoses for BPVC are, she is asking "what other disease could cause these symptoms?  What else could this be?"  Before a doctor makes a final diagnosis, they must think of what other medical conditions have the same or similar symptoms, and make sure one of them is not the problem.
