2020-07-07 · Lichenoid actinic keratosis will show some degree of interface change with associated lymphocytic infiltrate within the superficial dermis (see the second image below). Changes of lichen simplex chronicus accompany many atypical squamoproliferative lesions, such as hypertrophic actinic keratosis and squamous cell carcinoma.

The entire procedure time (shave biopsy and cryoablation) lasted less than 10 minutes. The subsequent pathologic report indicated that the excised lesion was a lichenoid keratosis. The lichenoid variant of actinic keratosis is characterized by a dense bandlike inflammatory infiltrate in the dermis. A pigmented variant is also recognized; it is characterized by an admixture of pigmented dendritic melanocytes and atypical keratinocytes. Lichenoid keratosis is a very common diagnosis with lesions most often occurring on the trunk and proximal upper limbs of middle-aged or older patients.
