Dermoscopy for pigmented basal cell carcinoma in Asian patients

皮膚鏡檢查在亞洲患者色素性基底細胞癌的應用

SH Tay, MMF Chan, CC Oh

Abstract

Introduction: Basal cell carcinoma (BCC) is the commonest skin cancer worldwide, with the pigmented subtype being more prevalent in Asians. In this case series, we aim to illustrate the value of dermoscopy in distinguishing pigmented BCC among Asians. Materials and methods: Six Chinese patients with six pigmented lesions that were clinically suspicious for pigmented BCC underwent dermoscopic evaluation and results were compared to their histopathological correlates. Results: All six lesions were confirmed to be pigmented nodular BCCs histopathologically. Up-to-date dermoscopic criteria for BCC were identified in all six lesions with shiny white lines, a newly added criterion, detected in four lesions. Conclusions: Dermoscopy is a useful non-invasive bedside tool which helps clinicians to differentiate pigmented BCC from other pigmented lesions. Shiny white lines is a potentially useful addition to the commonly accepted dermoscopic criteria for detecting pigmented BCC in Asians.

簡介:基底細胞癌是全球最常見的皮膚癌,其色素亞型在亞洲人中更為普遍。在本案例系列中,我們的目的是要說明皮膚鏡檢查在區分亞洲人的色素性基底細胞癌中的價值。取材和方法:對六名華裔患者身上共六個臨床疑似色素性基底細胞癌的色素沉著皮膚病變,進行皮膚鏡評估,並將其結果與其組織病理學相關性互相比較。結果:所有六個病灶經組織病理學證實為色素性結節性基底細胞癌。在所有六個病灶中都發現有最新的色素性基底細胞癌皮膚鏡檢查標準特徵,並且在四個病灶中發現了新的標準特徵「閃亮白線」。結論:皮膚鏡檢查是一種有用的非侵入性臨床工具,可幫助醫生將色素性基底細胞癌與其他色素性病變區分開來。閃亮白線可視為通用於檢測亞洲人色素性基底細胞癌的皮膚鏡檢查標準的潛在有用的補充特徵。
