Abstract

BACKGROUND

Pigmented Bowen's disease is not well characterized.

OBJECTIVE

To characterize the clinical and dermatoscopic appearance of pigmented Bowen's disease.

METHODS

We performed a retrospective analysis of 52 consecutive cases of pigmented Bowen's disease.

RESULTS

Of 951 histopathologically verified cases of Bowen's disease that underwent biopsy during the study period, 52 (5.5%) were pigmented. Dermatoscopically pigmented Bowen's disease is typified by a pattern of dots and/or structureless zones. In 21.2% (n=11), we observed brown or gray dots arranged in a linear fashion. Vessels were identified in 67.3% of lesions with a predomination of coiled vessels. A linear arrangement of vessels was seen in 11.5%.

LIMITATIONS

Conclusions are limited by the fact that this was a retrospective, uncontrolled study.

CONCLUSIONS

Pigmented Bowen's disease has a characteristic dermatoscopic pattern. Linear arrangement of brown and/or gray dots and/or coiled vessels is a specific clue to pigmented Bowen's disease.

摘要

背景

色素性 Bowen 病的特征尚未明确。

目的

描述色素性 Bowen 病的临床和皮肤镜表现。

方法

我们对 52 例连续的色素性 Bowen 病病例进行了回顾性分析。

结果

在研究期间接受活检的 951 例经组织病理学证实的 Bowen 病病例中，有 52 例（5.5%）为色素性。色素性 Bowen 病的皮肤镜表现为点和/或无结构区模式。我们观察到 21.2%（n=11）的病例中存在呈线性排列的棕色或灰色斑点。67.3%的病变存在血管，以卷曲血管为主。11.5%的病例可见线性排列的血管。
