Dermoscopic Polymorphism of a Pigmented Eccrine Poroma on the Leg: A Diagnostic Pitfall.
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
Pigmented eccrine poroma (PEP) is a rare benign adnexal tumor that can closely mimic melanoma clinically and dermoscopically, particularly when it occurs on non-acral locations. We report the case of a 31-year-old man who presented with a slow-growing, well-circumscribed brown nodule on his left leg that had been evolving for four years. Dermoscopy revealed a polymorphic pattern with chalice-form vessels, perivascular white halos, a frog's egg appearance, and structureless blue and white areas suggestive of melanoma. Histopathological examination confirmed the diagnosis of pigmented eccrine poroma. Complete surgical excision was performed with no recurrence at two-year follow-up. This case highlights the importance of recognizing the characteristic dermoscopic features of PEP to avoid unnecessary aggressive procedures and patient anxiety.
