Reverse Koebnerization in a linear oral lichenoid lesion: A case report

Prashanth Panta et al. Clin Pract. .

Abstract

The spectacle of Koebner's phenomenon (KP) is interesting in that trauma precipitates a subset of pathologically distinct conditions, indicating the subtle interplay between sensitization and dermato-mucosal integrity. KP is interesting because, if factors initiating it are controlled, then it may be possible to prevent these debilitating conditions through induction of reverse Koebnerization. Herein, we present a report of a patient with an erosive lesion, localized to the occlusal plane on buccal and lingual mucosa, that interestingly subsided following 1 week after a dental scaling procedure. This report analytically describes the role of dental calculus and cuspal trauma as important triggers surrounding the genesis of oral lichenoid lesion and oral lichen planus. An engaging discussion on these closely related enigmatic entities forms the central theme of this report.

Keywords: Dental calculus; Koebner phenomena; Oral lichen planus; Oral lichenoid lesion; Reverse Koebnerization.

Figures

Figure 1.
Figure 1.
A linear erosive lesion is seen on the right buccal mucosa, along the line-ofocclusion, extending from molar region to right commissure area. Severe calculus is notable around several teeth, even on the occlusal surfaces. No prosthesis or dental fillings are present.
Figure 2.
Figure 2.
A similar linear erosive lesion is notable along the right lateral border of tongue, along the line-of-occlusion, in close proximity with the dental cusps of posterior teeth and incisal edges of anterior teeth. Surrounding this lesion, faint whitish lines can be seen.
Figure 3.
Figure 3.
Severe dental plaque and calculus notable in lower teeth on right and left side. Erosive lesions are however typically seen on right gingiva (interdental and free gingiva) and labial mucosa, in close proximity with plaque and calculus. Milder form of erosion is seen on left gingiva.

Regression of buccal lesion following 7 days after a dental scaling procedure.

Lesion regression on right side of lateral tongue, following 7 days after a scaling procedure. In the background, faint white lines are clearly visible on tongue dorsum.
