Evaluation of dermoscopic findings in patients with cutaneous squamous cell carcinoma according to histopathological subtype and lesion morphology.

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
backgroundCutaneous squamous cell carcinoma (cSCC) includes in situ cSCC (Bowen's disease [BD]) and invasive cSCC. By contrast, keratoacanthoma (KA) is a well-differentiated cSCC with self-resolving tendencies. Dermoscopy aids in monitoring vascular and keratin pattern changes to diagnose and track cSCC invasion.
objectivesTo examine dermoscopic findings of cSCC according to histopathological differentiation and clinical morphological characteristics.
methodsClinical and dermoscopic images of 118 cSCCs were retrospectively examined.
resultsCompared to other cSCC subtypes, BD more frequently presented with pigmentation (p = 0.028) and a clustered (p = 0.042) or serpiginous (p = 0.006) vascular arrangement. Central keratin plugs were more common in well-differentiated invasive cSCCs (p = 0.021), while white circles surrounding follicles (p < 0.001), ulceration/bleeding (p = 0.001), and red background (p = 0.004) were observed more in poorly differentiated invasive cSCCs. Central keratin plugs (87.5%) and branched vascular arrangements (75%) were observed in patients with nodular KA, with both statistically more frequent than in invasive cSCC (p < 0.001, p = 0.040, respectively). White halos surrounding vessels (p = 0.004) and a clustered vessel arrangement (p = 0.037) were more common in nodular invasive cSCC compared to nodular KA. STUDY LIMITATIONS: The number of examined lesions in the subgroups was relatively small.
conclusionsDermoscopy aids in distinguishing well-differentiated invasive cSCC from poorly differentiated invasive cSCC, distinguishing nodular KA from nodular invasive cSCC, and diagnosing BD. Further studies are needed to identify dermoscopic findings that can distinguish moderately differentiated invasive cSCC from other invasive cSCCs.
