摘要

我们报告一例69岁男性肺肉瘤样癌（PSC）患者。他以疲劳和厌食症来我院就诊。增强胸部计算机断层扫描显示肿块边缘平滑，内部无增强，仅在右下叶周围可见。最初，怀疑是肺脓肿，并服用了两周的抗生素。然而，发热、影像学检查和血液检查均未见好转。考虑到恶性肿瘤的可能性，患者接受了右下肺叶切除术。组织病理学诊断为肉瘤样癌。PSC非常罕见，在本病例中很难与肺脓肿区分。在此，我们详细讨论该病例的进展和组织病理学。

Pulmonary sarcomatoid carcinoma presenting as a lung abscess: A case report

We report the case of a 69-year-old male patient with pulmonary sarcomatoid carcinoma (PSC). He presented to our hospital with fatigue and anorexia. Enhanced chest computed tomography revealed a mass with smooth margins and no contrast enhancement within, only observed around it in the right lower lobe. Initially, a lung abscess was suspected, and antibiotics were administered for two weeks. Nevertheless, fever, imaging findings, and blood tests showed no improvement. Considering the possibility of a malignant tumor, the patient underwent a right lower lobectomy. The histopathological diagnosis was sarcomatoid carcinoma. PSC is very rare and was difficult to distinguish from a lung abscess in this case. Herein, we discuss the progress and histopathology of this case in detail.
