Abstract
BACKGROUND Flagellate dermatitis caused by the intake of shiitake mushrooms is characterized by linear erythematous lesions that are intensely pruritic. It is common in countries where the consumption of mushrooms is high, but it is rare in Latin America. It can be difficult to diagnose as there is a delay between the intake of the mushroom and the eruption. CASE REPORT A 49-year-old Caucasian woman with a history of hypothyroidism who, 48 hours after the intake of shiitake mushrooms, developed intense itching associated with the appearance of linear and erythematous lesions, in a "flagellate-like" pattern, predominantly on the trunk, without other signs or symptoms. There was no history of recent exposure to drugs. She was treated with oral antihistamine and topical corticosteroid, however, without improvement, which is why a short cycle of oral corticosteroid was required, with which her lesions were resolved. A shiitake-free diet was indicated. CONCLUSIONS Flagellate dermatitis is a toxicoderma that is associated with the intake of shiitake mushrooms among other things. Its clinical presentation is characteristic, although its exact pathophysiology is not fully understood. The boom of Asian food in Latin America might lead to an increase in the number of cases; hence the importance of knowing about its existence.

Food-Dependent, Exercise-Induced Anaphylaxis: Diagnosis and Management in the Outpatient Setting.

Abstract
Food-dependent, exercise-induced anaphylaxis is a disorder in which anaphylaxis develops most predictably during exercise, when exercise takes place within a few hours of ingesting a specific food. IgE to that food should be demonstrable. It is the combination of the food and exercise that precipitates attacks, whereas the food and exercise are each tolerated independently. Recently, it was demonstrated that exercise is not essential for the development of symptoms, and that if enough of the culprit food is ingested, often with additional augmentation factors, such as alcohol or acetylsalicylic acid, symptoms can be induced at rest in the challenge setting. Thus, food-dependent, exercise-induced anaphylaxis appears to be more correctly characterized as a food allergy syndrome in which symptoms develop only in the presence of various augmentation factors, with exercise being the primary one. However, additional factors are not usually present when the patient exercises normally, so ongoing investigation is needed into the physiologic and cellular changes that occur during exercise to facilitate food-induced anaphylaxis.
