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.
