Introduction
Keratosis lichenoides chronica (KLC) is a rare dermatosis with a chronic progressive course. Characteristically KLC presents as violaceous, keratotic, lichenoid papules with a linear or reticulated arrangement with symmetrical distribution on the extremities and the trunk (1). Another prominent feature is a seborrhoeic dermatitis- or a rosacea-like eruption on the face. Additionally, oral manifestations such as recurrent aphtha, large chronic ulcers or erythrokeratotic papules occur in 50% of patients.
Although KLC manifests more commonly in adults (20-40 years), there are some reports of the disease appearing in childhood (1, 2). It has been suggested that the disease represents different clinical characteristics between adult- and pediatric-onset cases(3). We describe a patient with the manifestations of adult-onset KLC beginning from infancy.
