Collision tumor is a term used to refer to the association of various types of tumors in time and space. Despite most of them not being clinically relevant, sometimes there is a union between a benign lesion and a malignant one. The clinical diagnosis in these cases is usually extremely difficult, particularly if one of the lesions is pigmented. Dermoscopy and confocal microscopy are noninvasive diagnostic methods that make possible the visualization of morphologic structures not visible to the naked eye, thus making diagnosis of these lesions possible. Here we describe a case in which the corrected diagnosis of a collision between a seborrheic keratosis and a basal cell carcinoma was only possible by means of confocal microscopy.
碰撞瘤是一个用于指代不同类型肿瘤在时间和空间上关联的术语。尽管它们中的大多数在临床上并无关联，但有时良性病变与恶性病变会合并存在。这些病例的临床诊断通常极其困难，尤其是当其中一个病变有色素沉着时。皮肤镜检查和共聚焦显微镜检查是无创诊断方法，能够使肉眼不可见的形态结构可视化，从而使这些病变的诊断成为可能。在此，我们描述了一例病例，其中脂溢性角化病与基底细胞癌碰撞的正确诊断仅通过共聚焦显微镜检查才得以实现。
