Concomitant Systemic Lupus Erythematosus and Glanzmann Thrombocytopenia: A Case Report and Literature Review

<b>Background:</b> Glanzmann thrombasthenia (GT) is a rare disease that manifests with bleeding in different parts such as epistaxis and bruising. GT can be congenital or acquired. Systemic lupus erythematosus (SLE) is an autoimmune disorder. It is mentioned that the acquired type can be associated with other disorders like malignancies and autoimmune disorders. There is no report about the co-occurrence of congenital GT with SLE. <b>Case Report:</b> In this report, we present this co-occurrence in a girl. An 11-year-old girl was referred to our clinic with severe and uncontrolled epistaxis. She had a history of recurrent epistaxis, gastrointestinal bleeding, and bruising. She also had a malar rash and generalized body pain. She was admitted, and after clinical and laboratory assessments, a co-occurrence of congenital GT with SLE was diagnosed. <b>Conclusion:</b> The co-occurrence of congenital GT and SLE has not been reported until now. Patients with this presentation should be closely followed up because the risk of bleeding is high for them.
