Osimertinib-Induced Cutaneous Vasculitis Responsive to Low-Dose Dapsone Without Interruption of Anticancer Therapy: A Case Report and Review of the Literature.
Article in JTO clinical and research reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A 45-year-old woman with a history of lung adenocarcinoma treated with osimertinib developed purpuric plaques and vesicles on the lower extremities after 5 months of therapy. Skin biopsy revealed leukocytoclastic vasculitis (LCV). A workup for systemic involvement was unremarkable. The patient was treated with oral dapsone while continuing osimertinib without interruption. Skin lesions cleared within 2 weeks of therapy with no recurrence after titrating off dapsone. To the best of our knowledge, this is the first reported case of LCV induced by a small-molecule EGFR inhibitor in which therapy was not interrupted. This is also the first reported case treated with dapsone rather than systemic corticosteroids. We suggest consideration of dapsone to treat skin-limited LCV induced by EGFR inhibitors in patients with lung cancer without features of systemic vasculitis. In addition, this case highlights that it may not be necessary to stop EGFR inhibitor therapy in the absence of severe features such as ulceration, bullae, necrosis, or severe pain. Dapsone is an effective targeted therapy for cutaneous LCV that does not globally impair the immune system and may allow for uninterrupted treatment of the underlying malignancy.
