Pathognomonic (often misspelled as pathognomic and sometimes as pathomnemonic) is an adjective of Greek origin, often used in medicine, which means diagnostic for a particular disease.
A pathognomonic sign is a particular sign whose presence means, beyond any doubt, that a particular disease is present. It is derived from the Greek páthos (πάθος, disease) and gnōmon (γνώμον, "judge"). Labelling a sign or symptom "pathognomonic" represents a marked intensification of a "diagnostic" sign or symptom.
