Lichen planus-like keratosis: what do we know about it?

Abstract

Lichen planus-like keratosis is a common, benign pigmented skin lesion. It should be carefully diagnosed using modern diagnostic tools, such as dermoscopy and confocal microscopy, to avoid misdiagnosis as melanoma or other malignant pigmented lesions.

Dermoscopy: A reliable guide in the diagnosis of lichen planus-like keratosis in an appropriate clinical setting

“…e majority of the lesions belong to the classic variant (non-pigmented), and other rare variants include atrophic (pigmented), bullous, and mycosis fungoides-like. [1,2] In contrast to previously reported female preponderance, a recent study found an almost equal prevalence between males and females. e chest is the most commonly affected region, followed by the back and forearm, while the head and neck are not affected.…”

Lichen planus like keratosis: little known and misleading etiology of pigmented skin lesion

“…LPLK also known as benign lichenoid keratosis, is a common benign lesion that is of great relevance when it is mistakenly diagnosed as a malignant lesion such as basal cell carcinoma or melanoma. 1 It is believed to be an inflammatory process intended to clear residual seborrheic keratosis or solar lentigo that often disappears spontaneously within 3 to 18 months. 2,3 To support this diagnosis, evidence of the initial lesion disappearing is required, including the presence of remnant histological features in favor of seborrheic keratosis or solar lentigo.…”
