Disinfection of pets is important prevention for reinfection in patients with zoophilic dermatophytosis. A Wood’s lamp can be used to detect infected pets which have superficial fungal infections, especially <em>Microsporum canis</em>. However, the device is expensive, bulky and not readily available at every clinic. We reported a 49-year-old woman with <em>M. canis </em>dermatophytosis on the left arm and abdomen<em>. </em>Her asymptomatic cat showed no abnormal lesions; however, a standard Wood’s lamp and two handheld ultraviolet (UV) flashlights on the hair revealed areas of fluorescence. The affected hair under a handheld UV flashlight was collected for potassium hydroxide examination and fungal culture which yielded positive results. In summary, the handheld UV flashlights can detect <em>M. canis</em> infection in pets with similar efficacy to that of the original Wood’s lamp.</p> ER -
