title: Delayed hypersensitivity to 6-methyl-prednisolone in Henoch Schöenlein syndrome.
abstract: We report a case of allergic reaction to oral 6-methyl-prednisolone in a patient with Henoch Schöenlein syndrome. When this syndrome was first diagnosed the patient was started on 6-methyl-prednisolone orally and after 4 days he developed a pruriginous generalized maculo-papular eruption. The rash disappeared 1 week after withdrawal of 6-methyl-prednisolone. The skin tests performed 1 month after with main food allergens were negative. Patch test with 0.10 ml of solution containing 6-methyl-prednisolone 40 mg/ml was positive after 48 and 72 h. The cutaneous biopsy on the patch tested skin revealed a perivascular infiltrate of lymphocytes, histiocytes and eosinophils.
