Benign Lichenoid Keratoses, also called Lichen Planus Like Keratoses, are one of the most common skin lesions I encounter in both my The Woodlands and Conroe area patients. Clinically, Benign Lichenoid Keratoses causes red slightly scaly plaques that are almost clinically identical to superficial basal cell cancers. Benign Lichenoid Keratoses have to be biopsied to rule out skin cancer. Benign Lichenoid Keratoses is commonly found on the arms, hands and chest and is very common in middle aged white women. Histologically, they are identical to lichen planus with a band like inflammatory lichenoid infiltrate in the papillary dermis. Benign Lichenoid Keratoses may arise from solar lentigos (freckles). Since Benign Lichenoid Keratoses can be itchy and symptomatic, liquid nitrogen is usually and effective treatment for these symptoms.
