Every decade, people around the globe come forward to claim that they spontaneously bleed and bruise without an injury, disease or chemical to cause it.
Stigmata might first come to mind, but there are many terms for the spontaneous bleeding -- psychogenic purpura, autoerythrocyte sensitization, Gardner-Diamond syndrome -- and just as many different reactions to the claims.
