Atypical manifestations of tinea corporis.
Tinea corporis classically presents as an erythematous annular plaque with a scaly, centrifugally advancing border. However, sometimes vesicles and pustules are observed. Occasionally, even frank bullae appear secondary to severe inflammation. Diagnostic difficulties arise when atypical manifestations mimic other inflammatory skin diseases, including atopic or seborrheic dermatitis, subacute cutaneous lupus erythematosus, or vesicular diseases. We report five cases of atypical tinea corporis, where the initial clinical diagnosis was different from dermatophytosis. The differential diagnoses and the diagnostic difficulties related to atypical manifestations of fungal infections are discussed. Moreover, our cases emphasise the importance of conventional histological examination, which enables a fast, correct diagnosis.
