背景:皮肤镜检查可用于诊断基底细胞癌(BCC)。然而,BCC的皮肤镜特征的大多数描述是在高加索人(I-III型皮肤)中,而深色皮肤的印度患者的数据很少。
目的:这项研究的目的是描述印度南部深色皮肤患者BCC的各种皮肤镜特征,并将其与组织病理学亚型相关联。
方法:在印度南部的三级护理中心使用非极化接触皮肤镜检查对活检证实的BCC病例进行了回顾性观察研究。
结果:研究了35例以皮肤光型IV或V为主的BCC。其中包括32个结节,浅表性BCC27例,浸润性BCC1例。最常见的皮肤观察特征是枫叶状区域(61.7%),蓝白面纱(53.4%),溃疡(48.4%)和短的细毛细血管扩张酶(46.7%)。溃疡,蓝白色面纱和树状血管与结节性BCC显着相关,而枫叶状区域,红白无结构区域,多个小侵蚀和辐条车轮区域被发现有浅表BCC。
结论:本研究的局限性包括其回顾性性质,仅使用非偏振光进行检查,缺乏BCC的其他组织病理学变异以及缺乏对照组。
结论:我们报告了来自Puducherry的深色皮肤患者的皮肤镜检查研究,南印度。在一半的患者中观察到蓝白色面纱,并且与结节性BCC显着相关。在色素性BCC的诊断标准中添加蓝白色面纱可以提高印度患者皮肤镜检查的诊断准确性。
BACKGROUND: Dermoscopy is useful in the diagnosis of basal cell carcinoma (BCC). However, most descriptions of the dermoscopic features of BCCs are in Caucasians (skin types I-III) and there is a paucity of data in dark-skinned Indian patients.
OBJECTIVE: The aim of this study was to describe the various dermoscopic features of BCC in dark-skinned patients from South India and correlate these with the histopathologic subtypes.
METHODS: A retrospective observational study of biopsy-proven cases of BCC was conducted at a tertiary care center in South India using nonpolarized contact dermoscopy.
RESULTS: Sixty BCCs in 35 patients predominantly of skin phototypes IV or V were studied. These included 32 nodular, 27 superficial and 1 infiltrative type of BCC. The most common dermoscopic features noted were maple leaf-like areas (61.7%), blue-white veils (53.4%), ulceration (48.4%) and short fine telangiectases (46.7%). Ulceration, blue-white veils and arborizing vessels were significantly associated with nodular BCCs, while maple leaf-like areas, red-white structureless areas, multiple small erosions and spoke wheel areas were noted with superficial BCCs.
CONCLUSIONS: The limitations of this study include its retrospective nature, the use of only nonpolarized light for examination, the lack of other histopathological variants of BCC as well as the lack of a comparison group.
CONCLUSIONS: We report a dermoscopic study of BCC in dark-skinned patients from Puducherry, South India. The blue-white veil was observed in half of the patients and was significantly associated with nodular BCCs. The addition of the blue-white veil to the diagnostic criteria for pigmented BCC could improve the diagnostic accuracy of dermoscopy in Indian patients.
