Abstract

A 21-year-old Chinese man presented with four years' history of recurrent itchy erythematous papules and reticulated hyperpigmentation over the upper back and chest wall. The diagnosis of prurigo pigmentosa was made. Treatment with oral doxycycline resulted in reduction of pruritus and no emergence of new lesions. Clinical features, histological features and treatment of prurigo pigmentosa will be discussed.
