OBJECTIVE Patients with Covid-19 can have different symptoms, ranging from asymptomatic patients to various grades of respiratory failure, caused by typical interstitial pneumonia, cardiac involvement or neurological symptoms. PATIENTS AND METHODS In April 2020, we focused our attention on a young woman with diffused purpura on her lower extremities, with no respiratory, cardiac or neurological symptoms. A complete blood analysis showed us a severe thrombocytopenia. We excluded other possible causes of thrombocytopenic purpura such as hematological (lymphocyte subsets), hepatological disease or splenomegaly. On autoimmune screening, we found Isolated immune thrombocytopenic purpura in a young adult Covid-19 patient positivity of anti-nuclear antibody (ANA) with a centrosome pattern and extractable nuclear antigens (ENA) and connective tissue disease screen resulted positive but none of the included specific antigens results positive, probably due to an aspecific antibody reaction. The wide variability of COVID disease presentation may be due to a personal different immune response to the virus. CONCLUSIONS The immune response against the virus is crucial in the evolution and understanding of COVID-19 disease but it has still to be fully understood.
