a case report of intrapulmonary mature cystic teratoma of the lung

Introduction: intrapulmonarymature cystic teratoma is an extremely rare form of extragonadal teratoma that frequently presents with nonspecific clinical and radiologic findings. the first case was described by mohr in 1839. it usually involves the upper lobes of the left lung. case presentation: in this report, we describe the first case of a 28-year-old woman from kabul, afghanistan, who was diagnosed with intrapulmonary mature cystic teratoma in the left upper lobe and complained of dry cough and hemoptysis 6 months before her admission. preoperatively, the clinicians suggested a diagnosis of lung abscess based on the symptoms and radiological findings. postoperatively, the lesion was diagnosed as intrapulmonary mature cystic teratoma by anatomopathological examination. conclusions: intrapulmonary mature cystic teratomas are usually misdiagnosed preoperatively due to nonspecific clinical symptoms, and indistinguishable radiographic findings, and should keep in the differential diagnosis of all cystic lesions. an accurate diagnosis is made by postoperative anatomopathological examination, and complete surgical resection of the lesion is considered the optimal treatment.
