IgA negative immunofluorescence in diagnoses of adult-onset Henoch-Sch önlein purpura.

We describe two cases of young adult men presenting with diffuse petechial rash and gastrointestinal disturbances. They were found to have leukocytoclastic vasculitis without immunoglobulin A findings under direct immunofluorescence on skin biopsy histopathology performed over a week after the appearance of lesions. Henoch Schönlein purpura (HSP) was diagnosed based upon the clinical presentation as well as the leukocytoclastic vasculitis biopsy findings. PMID: 32675977 [PubMed]
