Synovial sarcoma is a rare malignant mesenchymal neoplasm primarily affecting adolescents and young adults, and it typically arises from deep soft tissues near large joints. Although commonly found in extremities, it can occur in various anatomic locations. We present a rare case of a 29-year-old man with primary pulmonary synovial sarcoma manifesting as a cystic mass masquerading as a lung hydatid cyst. Histopathologic examination, immunohistochemistry, and molecular analysis aided in accurate diagnosis. This case underscores the importance of considering synovial sarcoma in the differential diagnosis of pulmonary cysts and highlights the crucial role of pathologic examination in guiding treatment decisions.
滑膜肉瘤是一种罕见的恶性间叶性肿瘤，主要影响青少年和年轻成年人，通常起源于大关节附近的深部软组织。虽然常见于四肢，但也可发生于各种解剖部位。我们报告一例罕见的29岁男性原发性肺滑膜肉瘤病例，表现为囊性肿块，伪装成肺包虫囊肿。组织病理学检查、免疫组织化学和分子分析有助于准确诊断。该病例强调了在肺囊肿鉴别诊断中考虑滑膜肉瘤的重要性，并突出了病理检查在指导治疗决策中的关键作用。
