Longitudinal Melanonychia as a Presenting Sign of Onychopapilloma: A Case Report and Review of the Literature.

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
Onychopapilloma is a benign tumor of the nail unit characterized by broad clinical variability, which frequently delays diagnosis. It typically presents as longitudinal erythronychia, melanonychia, subungual hyperkeratosis, or a distal nail mass. We report a 65-year-old woman with a chronic single-digit nail lesion initially misdiagnosed as onychomycosis. Dermoscopy revealed distal hyperkeratosis and a subungual mass. Histopathological examination confirmed onychopapilloma, and complete surgical excision resulted in symptom resolution. This report underscores the importance of distinguishing this entity from malignant nail tumors and highlights the diagnostic value of dermoscopy and histopathology. Early recognition may prevent diagnostic delay and unnecessary treatments.
