Shiitake dermatitis: the first case reported in Brazil

Abstract

Shiitake Dermatitis is often presented as papules and erythemato-violaceous linear streaks. It can be associated with bleomycin treatment, dermatomyositis and shiitake mushroom (Lentinus edodes). There is not any previous report concerning this rare etiology in our country. Shiitake is the second most consumed mushroom worldwide and it can cause flagellate erythema when ingested raw or half cooked. It has a higher incidence in Oriental countries because of their eating habits, this is the first case reported in Brazil, in a male patient that presented a cutaneous rash after consuming this raw mushroom.
