There are a few hypopigmented areas on the abdomen and left antecubital fossa. No lesions are present in the buccal mucosa.Biopsy specimen from the abdomen revealed hyperkeratosis, prominent granular layer, acanthosis with irregular lengthening of the rete ridges, destruction of the basal layer, and a band-like infiltrate in the upper dermis of lymphocytes extending to and invading the epidermis. A specimen from the back revealed keratinized epidermis with dense connective tissue dermis. The upper portion of the dermis contained two circumscribed collections of lymphocytes and histiocytes. Compression of the overlying epidermis produced focal dissolution of the basal cell
