Abstract
A 9-year-old boy presented with a history of keratotic violaceous plaques on the limbs and face for 8 years that had gradually progressed to erosive nodules on the extremities for 2 years. Several biopsies revealed hyperkeratosis, liquefactive degeneration of the basal layer, and a bandlike predominantly lymphocytic infiltrate. Based on the clinical and histologic findings, the patient was diagnosed with keratosis lichenoides chronica, a rare chronic dermatosis that is particularly uncommon in childhood. There are fewer than 20 reported cases of pediatric-onset keratosis lichenoides chronica in the current literature, with occurrence of pseudoepitheliomatous hyperplasia of primary keratosis lichenoides chronica lesions being even rarer. Here we present a unique pediatric-onset case accompanied by pseudoepitheliomatous hyperplasia that posed a significant treatment challenge to dermatologists. Significant improvement in the pseudoepitheliomatous skin lesions was achieved after treatment with oral acitretin capsules and surgical excision with skin grafting.
