The coiled and dotted vessels in a serpiginous arrangement or "string of pearls" is considered a classical vascular pattern associated with clear cell acanthoma. We present three cases of epidermal tumors different from clear cell acanthoma that have the same "string of pearls" vascular pattern. Even though most authors keep considering the "string of pearls" vascular pattern an almost pathognomonic sign of clear-cell acanthoma, the cases presented here suggest that some other epidermal tumors can also show this pattern.
呈匐行状排列或“珍珠串”样的盘绕状和点状血管被认为是与透明细胞棘皮瘤相关的经典血管模式。我们报告了三例不同于透明细胞棘皮瘤但具有相同“珍珠串”血管模式的表皮肿瘤。尽管大多数作者一直认为“珍珠串”血管模式几乎是透明细胞棘皮瘤的特征性表现，但本文所报告的病例表明，其他一些表皮肿瘤也可呈现这种模式。
