患者在五个月大时首次出现，右前头皮出现黄色斑块。六个月后，他们的头皮右后侧出现色素沉着过度的疣状丘疹。五年来，这些斑点慢慢变大，但只停留在右脸、头皮和颈部。它们不痛也不痒，患者生长正常。右脸颊和前额有轻微凸起的黄色斑块，延伸到头皮的正面和侧面。与这些斑块相连的是色素沉着过度的疣状丘疹，从头皮后部到右侧颈部后部形成线条。
The patient first showed up at five months old with yellow patches on the right front of the scalp. By six months, they had hyperpigmented verrucous papules on the back right side of the scalp. Over the past five years, these spots slowly grew bigger but stayed only on the right side of the face, scalp, and neck. They aren't painful or itchy, and the patient is growing normally. The right cheek and forehead have slightly raised, yellow patches that stretch onto the front and side of the scalp. Connected to these patches are hyperpigmented, verrucous papules, forming lines from the back of the scalp to the back of the neck on the right side.

○ 诊断和治疗
由于疣的形状相似，因此应加以区分。表皮痣可以通过激光消融去除。
