Pulmonary carcinosarcoma is a very rare tumor, and its prognosis is usually worse than pulmonary carcinoma. We present a case with gigantic carcinosarcoma (10 x 7.7 x 7.2 cm) located in the right upper lobe, in which the discordance between the brief clinical course with limited symptoms and its large size are remarkable. No definite diagnosis was made preoperatively. He underwent right upper lobectomy and mediastinal lymph node dissection through thoracotomy. The postoperative course was smooth, and no tumor recurrence or metastasis was noted during the 9-month follow-up period. In the literature, carcinosarcoma have been divided into the endobronchial and peripheral types, which have different histological pictures. The controversy about pathology, diagnosis, and treatment of carcinosarcoma is also discussed.
肺肉瘤样癌是一种非常罕见的肿瘤，其预后通常比肺癌更差。我们报告一例位于右上叶的巨大肉瘤样癌（10×7.7×7.2 cm）病例，该病例临床病程短暂且症状有限，但肿瘤体积却很大，两者之间的差异显著。术前未明确诊断。他接受了开胸右上叶切除术和纵隔淋巴结清扫术。术后病程顺利，在9个月的随访期内未发现肿瘤复发或转移。在文献中，肉瘤样癌分为支气管内型和外周型，它们具有不同的组织学表现。本文还讨论了关于肉瘤样癌的病理学、诊断和治疗方面的争议。
