BACKGROUND/OBJECTIVES: Arteriovenous tumour is a distinct, benign, acquired vascular lesion that can be misdiagnosed.
A dermoscopic examination of 39 cases of arteriovenous tumours collected from four Spanish hospitals was performed to evaluate specific dermoscopic criteria and patterns.
The most common structures found were vascular, 95% of cases (37/39); 90% (35/39) were non-arborising telangiectasia. All the lesions except two (95%) had a homogeneous pigmentation background that was red in 30 cases (77%), bluish-red in three (8%), brown in two (5%) and blue or multicoloured in one case each. Lacunae were seen in only three cases (8%). Non-arborising telangiectasia on a reddish background was identified in 72% of cases.
Dermoscopy is helpful in improving the diagnosis of arteriovenous tumours and allows the observer to differentiate them from other cutaneous lesions such as other vascular tumours, basal cell carcinomas and melanomas.
背景/目的：动静脉肿瘤是一种独特的、良性的后天性血管病变，可能会被误诊。
对从四家西班牙医院收集的39例动静脉肿瘤进行皮肤镜检查，以评估特定的皮肤镜标准和模式。
最常见的结构是血管性的，占95%的病例（37/39）；90%（35/39）为非树枝状毛细血管扩张。除两例（95%）外，所有病变均有均匀的色素沉着背景，其中30例（77%）为红色，3例（8%）为蓝红色，2例（5%）为棕色，1例为蓝色或多色。仅3例（8%）可见腔隙。72%的病例在红色背景上可见非树枝状毛细血管扩张。
皮肤镜有助于提高动静脉肿瘤的诊断水平，并使观察者能够将其与其他皮肤病变如其他血管肿瘤、基底细胞癌和黑色素瘤区分开来。
