位于胸膜的肉瘤样肿瘤很难诊断，因为有许多可能的情况，如恶性间皮瘤和软组织肉瘤，必须在鉴别诊断中考虑。从肿瘤的位置来看，首先考虑的可能是肉瘤样恶性间皮瘤。如果患者有石棉暴露史或显示特征性厚胸膜，恶性间皮瘤的诊断是直截了当的。然而，如果病人没有石棉接触史，并显示局部肿块，作出正确的诊断是一个挑战。我们遇到了一个孤立的成骨肉瘤肿瘤位于胸膜的病人没有石棉接触史。这是很难作出诊断，我们在此讨论这种肿瘤的鉴别诊断，重点是肉瘤样局限性恶性间皮瘤（LMM）与骨肉瘤元素和胸膜外骨肉瘤。
A sarcomatoid tumor located in the pleura is difficult to diagnose because there are many possible conditions, such as malignant mesothelioma and soft tissue sarcomas, that must be considered in the differential diagnosis. From the location of the tumor, the first consideration might be sarcomatoid malignant mesothelioma. If the patient has a history of asbestos exposure or shows characteristic thick pleura, the diagnosis of malignant mesothelioma is straightforward. However, if the patient has no history of asbestos exposure and shows a localized mass, making the correct diagnosis is a challenge.We encountered a case of a solitary osteogenic sarcomatous tumor located in the pleura in a patient with no history of asbestos exposure. It was difficult to make the diagnosis, and we herein discuss the differential diagnosis of this tumor, focusing on sarcomatoid localized malignant mesothelioma (LMM) with osteosarcomatous elements and extraskeletal osteosarcoma of the pleura.
