We report a rare case of intravascular papillary endothelial hyperplasia (IPEH) of the cheek. This neoplasm, known as Masson's tumor, is an unusual vascular lesion of proliferating endothelial cells. It is usually confined to the lumen of preexisting vessels or vascular malformations. The principal significance of IPEH is its resemblance to a variety of benign and malignant diseases and possible misdiagnosis as such. Achieving a correct diagnosis is essential to avoid subjecting a patient to either unnecessarily aggressive or inadequate therapy. For this reason, awareness of this lesion is very important.
我们报告一例罕见的颊部血管内乳头状内皮增生（IPEH）病例。这种肿瘤，即所谓的马松瘤，是一种内皮细胞增生的不寻常血管病变。它通常局限于先前存在的血管或血管畸形的管腔内。IPEH的主要意义在于它与多种良性和恶性疾病相似，可能会被误诊为此类疾病。做出正确诊断对于避免让患者接受不必要的过度治疗或不充分治疗至关重要。因此，认识这种病变非常重要。
