The dermoscopic comma, zigzag, and bar code-like hairs: Markers of fungal infection of the hair follicles

Comma hair has been described as a specific dermoscopic feature of tinea capitis, however, it is not always present. Recognition of the additional dermoscopic features is therefore important. Furthermore, comma hair has never been shown to be applicable in fungal infection of the hair follicles on other parts of the body such as the eyebrows, axillary, or pubic areas. We encountered 13 Taiwanese patients who had been diagnosed with tinea capitis and evaluated their dermoscopic features using a nonpolarized, contact-type dermoscopic instrument with alcohol as the interface medium. Herein, we describe a woman with fungal infection of the eyebrow and present the under-recognized zigzag hair and bar code-like hairs for the first time.
