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

ABSTRACT:

Background

Cutaneous 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.

Objectives

To examine dermoscopic findings of cSCC according to histopathological differentiation and clinical morphological characteristics.

Methods

Clinical and dermoscopic images of 118 cSCCs were retrospectively examined.

Results

Compared 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-diffe
