Harnessing Digital Pathology Tools to Distinguish Hand Eczema From Palmar Psoriasis: A Quantitative Approach.
Article in Journal of cutaneous pathology, 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
backgroundDistinguishing hand eczema from palmar psoriasis is a common diagnostic challenge due to overlapping clinical and histopathological features.
objectiveThis study aimed to validate morphological and immunohistochemical criteria for differentiating these two conditions using the digital pathology tools QuPath and ImageJ.
methodsOne hundred forty-two histological samples with confirmed clinical diagnoses were stained with hematoxylin and eosin and subjected to immunohistochemical staining for CD3, CD15, CD20, CD123, S100, and PHH3. The samples were digitized for analysis. QuPath was used to automate annotation, segment epidermal layers, and measure rete ridge elongation, width, and suprapapillary epidermal thickness. Immunohistochemical markers were also analyzed using QuPath. ImageJ was employed to quantify spongiosis using color thresholding techniques.
resultsSuprapapillary epidermal thickness was significantly lower in psoriasis compared to eczema (p < 0.001; AUC = 0.72). Rete ridge elongation (p = 0.002; AUC = 0.704) and width (p < 0.001; AUC = 0.698) also showed significant differences. Furthermore, hypogranulosis was more pronounced in psoriasis (p = 0.012; AUC = 0.602), while S100-positive cells in the epidermis were more commonly observed in eczema (p = 0.013; AUC = 0.583).
conclusionQuantitative assessment of suprapapillary epidermal thickness and rete ridge morphology offers a reliable and objective method for differentiating palmar psoriasis from hand eczema, enhancing diagnostic accuracy.
