Abstract:
Prurigo pigmentosa is a rare inflammatory skin disease of unknown origin, mostly described in the ethnic Japanese population. Etiology and pathogenesis are not completely known. Tetracyclines or dapsone are the therapy of choice. A 17-year-old Swiss patient with Turkish parents presented with pruritic rash on the neck and trunk, which started after a diet. Under therapy with doxycycline over 5 weeks, complete healing with slight reticular hyperpigmentation was observed.
