title: Henoch-Schönlein purpura associated with solid-organ malignancies: three case reports and a literature review.
abstract: Adult Henoch-Schönlein purpura (HSP) is rarely associated with solid-organ malignancies. We describe here three adult patients with HSP diagnosed within 3 months of the diagnosis of associated solid-organ malignancies, including pulmonary, prostate, and renal carcinomas. Two patients had complete remission with a combination of immunosuppressive therapies and treatment of the associated malignancy. The third patient had partial remission with immunosuppressive therapies, but never received treatment for the associated malignancy and did not achieve complete remission before his death 10 months after diagnosis of HSP. These cases suggest that HSP associated with solid-organ malignancies may be resistant to immunosuppressive therapies without treatment of the associated malignancy. Therefore, evaluation for solid-organ malignancies should be considered in adult patients without an identifiable cause of HSP, especially if the disease is not self-limited or does not respond appropriately to treatment.
