咽部畸胎瘤甚为罕见。这类肿瘤多见于1岁以内的婴儿,极少见于成人。现报告1例如下。患者女,16岁。半年前觉咽部有一肿物,吞咽时可活动,但对吞咽食物尚无明显影响。后因肿物逐渐增大,吞咽干固食物困难而求治。检查见咽后壁与悬雍垂结合部有一椭圆形肿物,呈息肉状突出,基底部较宽,约5×1.5×1.5cm,可随吞咽上下活动。临床诊断:咽部新生物(淋巴瘤?)。在局麻下经电灼完整摘除肿物。病理检查肿物大小为4×2×2cm,表面有皮肤覆盖,并有毛发。切开为实性,灰白带黄色。部分区域似软骨组织。显微镜下,肿物表面被覆分化良好的表皮,其下有许多毛囊、皮脂腺和汗腺。深 Pharyngeal teratoma is very rare. Such tumors are more common in infants within 1 year of age and are rare in adults. The report 1 is for example below. Female patient, 16 years old. Six months ago, there was a tumor in the pharynx and it was active when swallowed, but there was no significant effect on swallowing food. Due to the gradual increase in the mass, it is difficult to swallow dry solid food and seek treatment. Examination showed that there was an oval mass in the junction of the posterior pharyngeal wall and the uvullar sulcus, showing a prominent polyp, and the base was wide, about 5 × 1.5 × 1.5 cm, and it could move up and down with swallowing. Clinical diagnosis: New pharyngeal organism (lymphoma?). Thoracic enucleation was performed under local anesthesia with electrocautery. Pathological examination of the tumor size is 4 × 2 × 2cm, the surface covered with skin, and hair. Cut to solid, grayish yellow. Some areas resemble cartilage. Under the microscope, the tumor surface is covered with a well-differentiated epidermis with many hair follicles, sebaceous glands, and sweat glands underneath it. deep
