Trichoepithelioma of the External Auditory Canal Mimicking Cholesteatoma.
Article in Cureus, 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
Trichoepithelioma is a benign tumor arising from hair follicles that most commonly appears on the face and is rarely seen in the external auditory canal (EAC). This case describes a male aged 90 years or older who presented with purulent ear drainage and hearing loss and was found to have trichoepithelioma in the EAC. Initial imaging and clinical examination suggested cholesteatoma in the EAC with bony erosion, for which surgical intervention was indicated. However, final pathology based on more extensive tissue sampling revealed trichoepithelioma of the anterior wall of the right EAC. This case demonstrates that suspicious lesions of the EAC may require more extensive tissue sampling to prevent misdiagnosis based solely on superficial tissue samples.
