Systemic lupus erythematosus (SLE) is an autoimmune disease with varying dermatological findings. We review a unique presentation of SLE with a literature review. A previously healthy early adolescent female presented with painful, oral mucosal bullae filled with sanguineous fluid. She endorsed a tender right knee, but examination revealed no additional abnormalities. CBC demonstrated severe pancytopaenia. Further workup, including Coombs positive RBCs and positive ANA, anti-Smith, and anti-dsDNA antibodies, confirmed Lupus as the aetiology of this patient’s presentation. A form of blistering SLE and resultant thrombocytopaenia was likely responsible for the patient’s oral manifestations. After receiving 60 g intravenous immunoglobulin and 3 days high-dose pulse corticosteroids, her dermatological symptoms resolved. Although cases of blistering SLE with mucosal bullae have been described in the literature, this is the first documented case of haemorrhagic mucosal bullae as the presenting symptom of thrombocytopaenia in SLE in a paediatric patient.
