Leiomiyosarkom, sýklýkla uterus, retroperitoneum ve intraabdominal bölgeden kaynaklanan, düz has hücrelerinin tümörüdür. Trakeabronþiyal aðaçta düz kas hücrelerinin çokluðuna raðmen primer pulmoner kas tümörleri çok nadirdir. Kýrk sekiz yaþýnda herhangi bir þikayeti olmayan erkek hasta, tesadüfen çekilen akciðer grafisinde lezyon saptanmasý nedeniyle merkezimize yönlendirilmiþti. Bilgisayarlý Toraks tomografisinde sað akciðer alt lobda 4x3 cm çaplý kitlesel lezyon izlendi. Fluorodeoksiglukoz (FDG) iþaretli Bilgisayarlý Tomografi Entegrasyonlu Positron Emisyon Tomografi (PET/CT) taramada lezyonun düþük FDG tutulumu mevcuttu. Tanýsal amaçlý tomografi rehberliðinde iðne aspirasyonlarý yapýldý. Histopatolojik tanýya ulaþýlamayýnca taný ve tedavi amacýyla cerrahi planlandý. Video yardýmlý toraks cerrahisi (VATS) ile alt lob wedge rezeksiyonu uygulanan hastanýn postoperatif patoloji sonucu akciðerin primer leiomiyosarkomu olarak yorumlandý.

Leiomyosarcoma is a tumor of the smooth muscle cells which frequently originates in the uterus, retro-peritoneum, and within the abdomen. Although there are a large number of smooth muscle cells in the tracheobronchial tree, primary pulmonary muscle tumors rarely occur. A 48-year-old male patient with no symptoms was admitted to our department following the inadvertent detection of a lesion in his chest x-ray. Through thoracic computerized tomography, a 4x3 cm diameter mass lesion was located in the lower right lobe. In the positron emission tomography-computed tomography (PET/CT) scan with a fluorodeoxyglucose (FDG) tracer, low FDG uptake was observed in the lesion. Computer tomography-guided needle aspirations were carried out. In the absence of a histopathological diagnosis, surgery was planned for diagnosis and treatment. A lower lobe wedge resection was completed using video-assisted thoracic surgery (VATS). A diagnosis of primary pulmonary leiomyosarcoma was made based on postoperative pathology results.
