An 81-year-old woman presented with bleeding from a soft elastic bulge on the right buccal mucosa. Her medical history included hypertension, chronic renal failure, hysterectomy and a goiter operation. Certain investigations, such as blood tests, which confirmed the minimum hemoglobin level of 5.3 g/dl, computed tomography and magnetic resonance imaging (MRI), were conducted. MRI revealed features confirming the presence of a tumor involving the right buccal mucosa with high signal in T2-enhanced image. Considering the provisional diagnosis and image findings, the tumor mass was excised and histopathological examination of the biopsy specimen confirmed the diagnosis of a canalicular adenoma. Under the diagnosis of various clinical departments, the anemic state of the patient might be chiefly attributed to the bleeding from the tumor. Herein, we report a rare case of a canalicular adenoma in the right buccal mucosa with anemia due to bleeding from the tumor.
一名81岁女性因右侧颊黏膜出现柔软、有弹性的肿物并伴有出血前来就诊。她的病史包括高血压、慢性肾衰竭、子宫切除术和甲状腺肿手术。进行了一些检查，如血液检查（证实血红蛋白最低水平为5.3 g/dl）、计算机断层扫描和磁共振成像（MRI）。MRI显示的特征证实存在累及右侧颊黏膜的肿瘤，在T2增强图像中呈高信号。考虑到初步诊断和影像检查结果，切除了肿瘤肿块，活检标本的组织病理学检查确诊为管状腺瘤。在多个临床科室的诊断下，患者的贫血状态可能主要归因于肿瘤出血。在此，我们报告一例罕见的右侧颊黏膜管状腺瘤病例，该患者因肿瘤出血导致贫血。
