Benign Lichenoid Keratosis

Benign lichenoid keratosis is a benign growth typically appearing on the trunk of older men and women.  Clinically, this can often be misinterpreted as a basal cell carcinoma as it has a very similar appearance.  A biopsy will demonstrate a lichenoid appearance, which is a histological pattern where these lesions derive their name.  These are benign lesions requiring no further treatment.


Lichenoid keratosis is also known as benign lichenoidkeratosis, solitary lichen planus, lichen planus-like keratosis and involuting lichenoid plaque. Lichenoid keratosis, is a condition where, usually, a solitary brown lesion turns red and becomes itchy. These lesions usually appear in an area that is exposed to the sun. They generally appear most on the forearms, hands or chest of middle aged white women. Lichenoid keratosis(LK) is a common benign skin growth that typically presents as an evolving single discrete papule on the trunk or upper extremities of adults. The clinical diagnoses included basal cell carcinoma, actinic keratosis, Bowen’s disease, and seborrheic keratosis. Histologically, lichenoid features prevailed, often indistinguishable from those of lichen planus. Although the majority of lesions occurred in sun-exposed skin and showed histologic evidence of solar elastosis, changes typical of carcinoma in situ were absent. The correct pathologic diagnosis of benign lichenoid keratosis was initially made in only seven cases.
