Kerion Celsi due to Microsporum Canis with a Dermatophytid Reaction

Microsporum (M.) canis is the most common fungus to cause tinea capitis in Europe, especially in the Mediterranean region and South and Central Europe. Fungal scalp infections caused by M. canis tend to be non-inflammatory. Recently, a growing number of cases of tinea capitis characterized by inflammatory infection caused by M. canis and M. gypseum have been registered. We present a case of highly inflammatory tinea capitis, also known as kerion celsi, caused by M. canis in a 6-year-old-patient. Scalp infections due to M. canis are a growing problem in dermatological practice. Changes in epidemiology, etiology, and clinical patterns of fungal infections due to M. canis are significant. Greater awareness of this problem is needed in order to establish proper diagnosis and successful treatment strategy for these patients.
