TRICHOPHYTON RUBRUM INFECTION SIMULATING ERYTHEMA PERSTANS

[摘要] An uncommon circinate and gyrate urticarial and erythematous eruption caused by T. rubrum is descr. which is clinically indistinguishable from the chronic variant of erythema multiforme known as erythema perstans. The absence of scaling in these lesions may unfortunately divert clinical suspicion from their mycotic origin It is suggested that intensive search for fungi is required in such cases because of the paucity of organisms, perhaps due to immunologic factors of the patient. Even during remissions of the eruption it may be possible to demonstrate the silent presence of T. rubrum in the area, accounting for the fixed recurrences of lesions.
