Abstract
Objective: The article provides and demonstrate the diagnosis of tinea capitis by Microsporum canis using the light of Wood (mini UV flashlight), a simple technique and low-cost for instrumental workup. Case details: 10-year-old, boy, with a case of tinea in the scalp caused by Microsporum canis. During the consultation, circular, scaly and tonsurant lesions were observed in the parietal region on the scalp of the child, who had close contact with dogs and cats. The semiotic technique used in the diagnosis was the mini UV flashlight that showed the typical greenish fluorescence of Microsporum canis. The treatment was started only based on this finding and, later, the mycological examination confirmed the etiology of the lesions. Final considerations: The diagnosis of tinea is frequently missed, unless we think of it and test for it. We concluded that the mini UV flashlight is useful in the diagnosis of tinea capitis, being an easy and low-cost technique.
