Abstract

Scratching suspected porokeratosis lesion, simple and quick maneuver that facilitates its diagnosis

Highlights

Porokeratosis are morphologically distinct keratinization disorders, characterized clinically by papules or hyperkeratotic plaques surrounded by a linear raised border
In the search for lesions that identified porokeratosis, a wooden tongue depressor was used to gently scratch one of the lesions (Fig. 1). This maneuver revealed a desquamative halo in the hyperkeratotic lesion (Fig. 2) - better identifying the clinical aspect typical of the porokeratosis
With the hypothesis of porokeratosis, the scraping of a suspected area identified a clearer halo and favored the diagnosis, confirmed later histologically. We suggest this simple maneuver that facilitates diagnosis in some cases where the porokeratosis frame is not so obvious

Summary

INTRODUCTION

Porokeratosis are morphologically distinct keratinization disorders, characterized clinically by papules or hyperkeratotic plaques surrounded by a linear raised border. A thin column of paracerathotic cells extends throughout the corneal extract and is seen in all variants This histopathological finding, known as the cornoid lamella, corresponds to clinically demonstrable hyperkeratosis [1,2,3,4,5,6,7,8,9,10]. In the search for lesions that identified porokeratosis, a wooden tongue depressor was used to gently scratch one of the lesions (Fig. 1). This maneuver revealed a desquamative halo in the hyperkeratotic lesion (Fig. 2) - better identifying the clinical aspect typical of the porokeratosis
