唾液腺嗜酸性腺瘤(下简称 OA)亦称嗜酸性颗粒细胞瘤、嗜酸细胞瘤、固缩细胞瘤等。文献记述本瘤少见,恶性更为罕见。亦有报导谓恶性并非更罕见。有必要对该瘤加强认识。一、OA 的发生率:Hastrup 统计文献中有130余例发生于腮腺的 OA,该瘤约占唾液腺肿瘤的0.5%左右(见表1)。唾液腺 OA 多发生于腮腺(85.25%),次为颌下腺(见表2)。多为单侧,约1/3病例 Salivary gland eosinophil adenoma (hereinafter abbreviated as OA) is also known as eosinophilic granulosa cell tumor, eosinophiloma, pyknotic cell tumor, and the like. The literature describes this tumor as rare, and the malignancy is more rare. There are also reports that malignancy is not rare. It is necessary to strengthen the understanding of this tumor. I. Incidence of OA: More than 130 cases in the Hastrup statistical literature occurred in the OA of the parotid gland, which accounts for approximately 0.5% of salivary gland tumours (see Table 1). Salivary gland OA occurred in the parotid gland (85.25%), followed by the submandibular gland (see Table 2). Mostly unilateral, about 1/3 cases
