Clinical observations of fourteen Japanese patients with prurigo pigmentosa, a peculiar pruritic pigmented dermatosis, were reported. Clinically the dermatosis is characterized by the sudden appearance of reddish papules accompanied by severe pruritus. Gross reticular pigmentation occurred after the disappearance of the papules. Histopathological findings of the papular lesions are non‐specific, although they show lichenoid tissue reactions. The dermatosis shows some preference for females, particularly in adolescence. Sites of predilection are the back, the nucha, the clavicular regions and the chest. Although the cause of the disease still remains unknown, it is speculated that some unknown environmental contaminant in today's Japan may play a role in the development of this dermatosis.
