Cutaneous-to-Bronchial Rosai-Dorfman Disease without Lymphadenopathy: A Rare Case Report and Literature Review.
Article in Clinical, cosmetic and investigational dermatology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Rosai-Dorfman disease (RDD) is a rare non-Langerhans cell histiocytosis that typically presents with massive cervical lymphadenopathy and systemic manifestations. The cutaneous form is usually limited to the skin and rarely progresses to systemic involvement. Timely confirmation of the diagnosis of RDD in cases of progression to systemic involvement is a challenge for the health care system. We report a 23-year-old woman with a history of COVID-19 infection and subsequent mRNA vaccination who developed acneiform eruptions on her face and at the vaccination site on her shoulder. Biopsies confirmed cutaneous RDD without lymphadenopathy. After more than one year of a purely cutaneous course, she developed cough and dyspnea. Imaging revealed an isolated bronchial lesion without lymph node involvement; histology confirmed RDD. The patient responded to local corticosteroid injections and systemic glucocorticoids, with stabilization of the disease. Our report underscores the importance of considering RDD in persistent acneiform eruptions unresponsive to treatment and bronchial masses without lymphadenopathy.
