Kerion Celsi favored by the use of a tretinoin+minoxidil+betamethasone valerate lotion in a 28-year-old woman.

Kerion Celsi is a parasitic fungal skin infection that tends to occur mainly on the back of the neck, scalp or beard. It is caused by animal fungi. Sometimes the condition resolves itself in a matter of weeks but hair loss in the affected area may be permanent. We report a case of a young woman with Kerion Celsi favored by the use of a tretinoin+minoxidil+betametasone valerate lotion.
