We describe a vascular lesion that develops secondary to trauma (pseudotraumatic aneurysm) and study its relation to epithelioid hemangioma (EH)/angiolymphoid hyperplasia with eosinophilia (ALHE). Four lesions are described, all with a distinct history of trauma to the site from which they arose. They presented with masses in the subcutaneous tissue of the head. They were studied by immunohistochemical methods to identify their component cells. The lesions all demonstrated marked thickening of the wall of small and medium-sized arteries, with capillary vascular proliferations. One lesion demonstrated increased eosinophils. Myxoid changes were noted in all lesions. We hypothesize that these lesions may represent an early form of EH/ALHE.
我们描述了一种继发于创伤的血管病变（假性创伤性动脉瘤），并研究了其与上皮样血管瘤（EH）/嗜酸性粒细胞增多性血管淋巴样增生症（ALHE）的关系。本文描述了4个病例，所有病例均有其发生部位明确的创伤史。它们表现为头部皮下组织肿块。通过免疫组化方法对其进行研究以识别其组成细胞。所有病变均显示中小动脉壁明显增厚，并伴有毛细血管增生。1个病变显示嗜酸性粒细胞增多。所有病变均可见黏液样改变。我们推测这些病变可能代表EH/ALHE的早期形式。
