As A Medical Sign
The presence of bruises may be seen in patients with platelet or coagulation disorders. Unexplained bruising may be a warning sign of child abuse, domestic abuse, or serious medical problems such as leukemia or meningoccocal infection. Unexplained bruising can also indicate internal bleeding or certain types of cancer. Long term glucocorticoid therapy can cause easy bruising. Bruising present around the navel (belly button) with severe abdominal pain suggests acute pancreatitis. Connective tissue disorders such as Ehlers-Danlos Syndrome may cause relatively easy or spontaneous bruising depending on the severity.
During an autopsy, bruises accompanying abrasions indicate the abrasions occurred while the individual was alive, as opposed to damage incurred after death.

Famous quotes containing the words medical and/or sign:
“Mark Twain didn’t psychoanalyze Huck Finn or Tom Sawyer. Dickens didn’t put Oliver Twist on the couch because he was hungry! Good copy comes out of people, Johnny, not out of a lot of explanatory medical terms.”
—Samuel Fuller (b. 1911)
“The visual is sorely undervalued in modern scholarship. Art history has attained only a fraction of the conceptual sophistication of literary criticism.... Drunk with self-love, criticism has hugely overestimated the centrality of language to western culture. It has failed to see the electrifying sign language of images.”
—Camille Paglia (b. 1947)
