Autoimmune thrombotic thrombocytopenic purpura associated with disseminated sarcoidosis: A case report.

Sarcoidosis is an inflammatory disease known to be associated with multiple autoimmune disorders. There is a restricted number of descriptions of the association between sarcoidosis and autoimmune thrombotic thrombocytopenic purpura (aTTP). We present the case of a 63-year-old woman admitted to the hospital to investigate a possible sarcoidosis who had hemolytic anemia and thrombocytopenia, with low ADAMTS13 activity and anti-ADAMTS13 antibodies, leading to a diagnosis of aTTP.
