1 · What the graph read from it

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.

2 · The registry

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

backgroundStudies have found that few lesions clinically diagnosed as seborrheic keratosis (SK) revealed Cutaneous melanoma (CM) on histopathology. When CM mimics SK, they are defined as seborrheic keratosis-like melanoma (SKLM), and a delayed diagnosis and treatment can occur.

methodsWe conducted a retrospective descriptive, monocentric study of the epidemiological, clinical, videodermoscopy (VDS), and reflectance confocal microscopy (RCM) characteristics of histopathologically proven SKLM diagnosed between 2018 and 2024.

resultsThe study population consisted of 60 patients: 44 males (73.3%) and 16 females (26.7%) with lesions located in 73.3% of cases on the trunk. Concerning histological type, superficial spreading melanoma was the more frequent (86.7%). More than 50% of tumors had a Breslow thickness <0.8 mm. The findings from the VDS examination using the revised Argenziano Seven Point Checklist revealed that 100% of cases presented at least one dermoscopic melanoma-specific criterion and, for this reason, had an indication for surgical excision. Typical RCM patterns associated with melanoma diagnosis were observed, including irregular honeycomb/cobblestone pattern (82.1%), irregular DEJ nests (78.6%), dermal inflammation (53.6%), irregular dermal nests (53.6%), dendritic cells in sheets/tangled lines (50%), and atypical round cells (39.3%).

conclusionOur study provides valuable insights into the dermoscopic, RCM, and histological features of SKLM based on the largest monocentric cohort. The distinctive dermoscopic patterns, along with the confocal features, aid in the differentiation from other pigmented lesions.
