Clinicopathological profile of subgemmal neurogenous plaques: A 52-year retrospective study of 22 cases.
Article in Medicina oral, patologia oral y cirugia bucal, 2025. 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
backgroundThis study describes the clinical and histopathological profile of 22 subgemmal neurogenous plaques (SNP) through a 52-year retrospective study conducted at an Oral Pathology referral center in the Northeast of Brazil. MATERIAL AND
methodsClinical data (age, biological sex, symptoms, clinical presentation, lesion size, duration at diagnosis, growth rate, implantation, and consistency) were retrieved from biopsy records. Hematoxylin and eosin-stained slides from all selected cases were re-evaluated.
resultsSNPs accounted for 0.12% (n = 22) of all lesions diagnosed at the center. A predominance among female patients was observed (n = 20; 90.9%), with most diagnoses occurring in the fifth to sixth decades of life (mean 57.5 ± 12.19 years). Clinically, the lesions typically presented as slow-growing but painful, reddish papules. Five cases were associated with oral lymphoepithelial cysts. Histologically, common features included spindle cells, subepithelial nerve plexuses, ganglion cells, mast cells, lymphoid tissue, and germinal centers.
conclusionsThese findings underscore the importance of recognizing the clinical and histopathological characteristics of SNPs to avoid misdiagnosis as neural tumors.
