A rare case report: Malignant transformation of lichen planus.
Article in Radiology case reports, 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
Lichen planus is a chronic inflammatory disease that mainly affects the skin and mucous membranes. Malignant transformation is uncommon and is most frequently reported in oral or genital lesions. We report a rare case of cutaneous lichen planus on the left lower leg that transformed into squamous cell carcinoma with left inguinal lymph node metastasis. 18F-FDG PET/CT demonstrated increased uptake in the primary skin lesion and metastatic lymph nodes, providing important information for staging and treatment planning. This case highlights the potential malignant transformation of long-standing cutaneous lichen planus and the value of PET/CT in evaluating disease extent.
