Ringworm of the Eyebrow

Cases of ringworm of the eyebrow are rare and are worth reporting. A white boy, aged 9 years, presented what looked like a patch of tinea circinata over the left eyebrow. The lesion was annular, about 3 cm. in diameter, with a slightly raised erythematous and scaly border and a center of almost normal skin. The hairs of the eyebrow seemed normal under ordinary light. Under Wood light, however, many of them showed yellowish-greenish fluorescence along their entire length. In addition, there were several erythematous and scaly lesions on the left nuchal area and a large focus on the left occipital area of the scalp, all with long fluorescent hairs. The patch on the scalp was visible only under Wood light and was unnoticeable under ordinary light, because there was neither erythema nor scaling and the hairs were not broken off short.
