Abstract

Angiolymphoid Hyperplasia with eosinophilia (ALHE) is considered a rare, benign vascular lesion that mainly affects the skin and subcutaneous tissues of the head and neck, but is uncommon in the oral cavity. Its etiology remains unclear and it has been described as a reactive vascular proliferation, vascular malformation or neoplasm. Kimura's disease is the primary entity to consider in differential diagnosis. Here we report on a rare case of ALHE involving the upper lip of a 50-year-old male patient that had a nodular swelling with approximately 3 cm, 7 years after initial onset. An excisional biopsy was performed and histopathologic examination revealed a well-encapsulated, multi-lobed lesion with proliferation of blood capillaries, displaying endothelial cells of epithelioid appearance, diffuse inflammatory infiltrate with lymphocytes, plasma cells, numerous eosinophils, and presence of lymphoid follicles. Immunohistochemical tests were positive for the markers CD34 and Ki-67 that, in combination with the results of morphological examination, were suggestive of a diagnosis of ALHE.

摘要

嗜酸性粒细胞增多性血管淋巴样增生(ALHE)被认为是一种罕见的良性血管病变,主要累及头颈部皮肤和皮下组织,但在口腔中并不常见。其病因尚不清楚,曾被描述为反应性血管增生、血管畸形或肿瘤。木村病是鉴别诊断中需考虑的主要疾病。在此,我们报告一例罕见的ALHE病例,该病例发生于一名50岁男性患者的上唇,初发7年后出现一个约3厘米的结节状肿胀。进行了切除活检,组织病理学检查显示为一个包膜完整、多叶状的病变,有毛细血管增生,可见上皮样外观的内皮细胞、淋巴细胞、浆细胞、大量嗜酸性粒细胞的弥漫性炎症浸润以及淋巴滤泡。免疫组织化学检测显示标记物CD34和Ki-67呈阳性,结合形态学检查结果,提示诊断为ALHE。
