  • 表現為肉色丘疹,但與基底細胞癌不同,觸感柔軟。
  • 前額多處皮脂腺增生。 ——典型案例。
  • 僅根據外觀很難與基底細胞癌區分開,但透過觸摸病變部位可以準確區分。

[Pinhole Technique] - 一名 15 歲男孩的臉頰上表情平靜。我們每 4 週使用 erbium : YAG 雷射 (continuous wave mode with a spot size of 1 mm) 進行 6 次針孔治療。皮損明顯改善,輕度紅斑,追蹤12個月未復發。一名 55 歲女性,右臉頰毛細血管擴張已有 10 年史。使用CO2雷射以針孔法治療毛細血管擴張。多個直徑 1 毫米的小孔深入真皮乳頭層。這些孔在整個毛細血管擴張區域中間隔約 3 毫米。 1次治療後,毛細血管擴張明顯改善。 3個月追蹤未見復發。
[Pinhole Technique] A 15-year-old boy presented with a CALM on his cheek. We performed 6 sessions of pinhole treatment every 4 weeks using erbium : YAG laser set to a continuous wave mode with a spot size of 1 mm. The lesion showed marked improvement with mild erythema, and there was no recurrence at the 12-month follow-up. A 55-year-old female presented with a 10-year history of telangiectasia on the right cheek. The telangiectasia was treated using the pinhole method using a CO2 laser. Multiple small holes, measuring 1 mm in diameter, were made down to the papillary dermis. These holes were made approximately 3 mm apart all over the telangiectasia area. The telangiectasia showed significant improvement after 1 treatment session. No recurrence was noted at the 3-month follow-up.
