根据胡、秦、刘三氏所著病理学记载:“混合瘤最多见于腮腺,然亦有生于颌下腺,舌下腺,颚、唇、眼皮、鼻、额、耳甚或四肢之皮下层等处者。国人患此病者颇多。因瘤组织除上皮细胞外更有欺骨或骨组织之形成,故名混合瘤”。我们体会三氏所指者概系涎腺混合瘤。实际混合瘤之组成部分,除有腺体外再包含一种或多种其他组织者皆可谓之混合廇。因之可有涎腺混合瘤,汗腺混合瘤,浆粘液腺混合瘤等等。因涎腺混合瘤之发生率最高。故一般所说的混合瘤概指涎腺混合瘤而言。此者多见于腮腺,少见于颌下腺或舌下腺,颚部或鼻 According to the pathological records written by Hu, Qin, and Liu Sanshi: “Mixed tumors are found most commonly in the parotid glands, but also in the submandibular glands, sublingual glands, palate, lips, eyelids, nose, forehead, ears, or even subcutaneous layers of limbs. There are many people in the country suffering from this disease, because the tumor tissue in addition to epithelial cells outside the formation of more bones or bone, hence the name mixed tumor.” We understand that the three refers to the Department of mixed tumors of the parotid gland. The components of the actual mixed tumor, except that the gland contains one or more other tissues in vitro, can be said to be mixed. Therefore, there may be mixed tumors of parotid glands, mixed tumors of sweat glands, and mixed tumors of pulp mucin glands. Because of the highest incidence of mixed tumors of the parotid gland. Therefore, the mixed tumor is generally referred to as a mixed tumor of the parotid gland. This is more common in the parotid gland, rare in the submandibular gland or sublingual gland, ankle or nose
