Five patients had persistent pruritic linear eruption, unresponsive to therapy. In four, the onset was in early childhood. Clinically, the lesions were characterized by discrete and confluent scaly erythematous papules. The histopathological features in each case were those of a chronic dermatitis. It is suggested that this disorder represents a dermatitic type of epidermal nevus.
