Abstract:
A 43-year-old, non-smoking man presented with acute ischemic lesions of his left hand. He had been taking beta-blockers for his arterial hypertension. The day before the occurrence of these acute lesions, he self medicated with a drug containing ergotamine and caffeine because of a headache. About one hour after mild trauma to the hand, he noticed intense cyanosis accompanied by severe pain in the fingers that progressed to digital necrosis. Hematological tests, hand radiography, echo Doppler, and nailfold videocapillaroscopy were performed. Digital necrosis owing to an unusual combination of ischemic mechanisms is assumed.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
