Case 1: (A) Macroscopic image showing an area of nonscarring alopecia, approximately 2.0x2.0 cm, without signs of inflammation, surrounding a 4-mm diameter well-circumscribed nevus, was observed in the left temporal region. (B) Dermoscopic image showed a well-circumscribed lesion with homogenous blue-grayish globular pattern, broken hairs, black dots, yellow dots and short vellus hairs. Case 2: (C) Macroscopic image revealed a patchy hair loss with a central nevus and surrounding hypopigmentation in the left temporal region. (D) With dermoscopy, we noticed a globular, dark brown pigmented tumor with peripheral areas of light-brown pigment, short vellus hairs and broken hairs. (E) Wood's light examination of the area of alopecia was positive with fluorescence enhancement.

A 28-year-old Chinese male patient began to experience a patchy hair loss with a central nevus and surrounding hypopigmentation in the left temporal region two months ago, which increased in size progressively (Figure 1C). With dermoscopy, we noticed a globular, dark brown pigmented tumor with peripheral areas of light-brown pigment, short vellus hairs and broken hairs (Figure 1D). Wood's light examination of the area of alopecia was positive with fluorescence enhancement (Figure 1E).
