A 61-year-old male patient presented with petechiae on the arms and legs due to 
a thrombocytopenia of 3 Gpt/l (3000/microl). A butterfly rash on the patient's 
face suggested a diagnosis of systemic lupus erythematosus (SLE). The 
thrombocytopenia was due to autoimmune thrombocytopenia. The diagnosis of SLE 
could be excluded and the butterfly rash attributed to a laminar hemorrhage, an 
ecchymosis due to the autoimmune thrombocytopenia.
