Teratomas are rare germ cell tumors usually found in the gonads. Extra-gonadal teratomas are especially rare, mostly occurring in the thorax. Only a few cases of intrathoracic teratomas have been reported in medical literature and most reported were located in the mediastinum. An additional intrathoracic location for teratoma occurrence is in the pulmonary system, most commonly in the upper lobe of the left lung. In this report, we describe a case of a 35-year-old woman diagnosed with an intrapulmonary mature teratoma found in the right upper lobe. A 35-year-old Saudi female presented with a chief complaint of a three-week history of dry cough. Chest X-ray revealed a right-sided para-pericardial mass in the anterior mediastinum and a significant decrease in the size of the right middle lobe opacity. Subsequently, a chest computed tomography (CT) was performed and revealed a cystic mass in the right lung, which required removal by surgical intervention. The surgery was performed via a thoracoscopic approach and the tumor was excised with no complications. Intrapulmonary teratomas (IPT) usually present with vague and non-specific symptoms such as cough, hemoptysis, and chest pain. It is a rare condition without diagnostic features detected preoperatively, save for trichoptysis which is reported in approximately 13% of the cases. We report a rare appearance of mature IPT in the right upper lung zone which is an unusual location.
畸胎瘤是一种罕见的生殖细胞肿瘤，通常发生于性腺。性腺外畸胎瘤尤为罕见，大多发生于胸部。医学文献中仅报道过少数几例胸内畸胎瘤，且多数报道位于纵隔。畸胎瘤发生的另一个胸内位置是在肺部系统，最常见于左肺上叶。在本报告中，我们描述了一例35岁女性被诊断为右肺上叶肺内成熟畸胎瘤的病例。一名35岁的沙特女性以干咳三周的主诉就诊。胸部X光显示前纵隔右侧心包旁肿块，右中叶不透明区大小显著减小。随后进行了胸部计算机断层扫描（CT），显示右肺有一个囊性肿块，需要通过手术切除。手术通过胸腔镜进行，肿瘤被切除，无并发症。肺内畸胎瘤（IPT）通常表现为模糊且非特异性的症状，如咳嗽、咯血和胸痛。这是一种罕见的疾病，术前没有可检测到的诊断特征，除了约13%的病例报告有毛发咳出。我们报告了右肺上叶区成熟IPT的罕见表现，这是一个不寻常的位置。
