We report a rare case of prominent purpura induced by aspirin and enhanced
by alcohol. A 44-year-old woman presented with a history of generalized pur
pura. She drank alcohol once or twice a week and regularly took an analgesi
c preparation, containing aspirin and acetaminophen, for alleviation of hea
daches. When purpura was evident the patient's liver function was within no
rmal limits and her coagulation time was normal but her bleeding time was p
rolonged. Red blood cell, white blood cell and platelet counts were normal
but a poor response to platelet agonists demonstrated platelet dysfunction.
After stopping the analgesic and abstaining from alcohol for 5 days, plate
let aggregation, in response to the agonists, returned to normal and purpur
a disappeared. When the patient took further doses of the analgesic prepara
tion for 3 days for headache relief, but did not drink alcohol, platelet ag
gregation was again abnormal but purpura was only slight.
