The diagnosis of a small-diameter melanoma may be challenging. We report the case of a 57-year-old man with a small pigmented papular lesion (2.5-mm diameter) that was suspicious on dermoscopy. A more confident differential diagnosis between an atypical nevus and a melanoma was necessary for correct management. Reflectance confocal microscopy (RCM) allowed a confident diagnosis in this lesion, which was an invasive melanoma with 0.3-mm Breslow thickness. This case highlights the benefit of RCM to reach a confident diagnosis and correct management of a small-diameter invasive melanoma.
小直径黑素瘤的诊断可能具有挑战性。我们报告了一例 57 岁男性的小色素性丘疹性病变（直径 2.5 毫米），在皮肤镜检查下可疑。为了正确管理，需要对不典型痣和黑素瘤之间的更具信心的鉴别诊断。反射式共聚焦显微镜（RCM）使对该病变的明确诊断成为可能，该病变为浸润性黑素瘤，Breslow 厚度为 0.3 毫米。该病例强调了 RCM 对明确诊断和正确管理小直径浸润性黑素瘤的益处。
