A rare solitary pulmonary nodule: clear cell carcinoma

Clear cell tumor of the lung is a rare benign tumor. The current study presents the case of a 60-year-old man who had an abnormal pulmonary nodule at chest x-ray. A computed tomography (CT) scan of the patient’s lung showed a 2x2x1.5 cm solitary nodule in the anterior segment of the left upper lobe. The patient underwent a lobectomy for the tumor. The pathologic examination revealed sheets of large round or polygonal cells with clear cytoplasm and immunoreactive positivity for HMB-45 and NSE. Investigation with PET/CT scan showed no evidence of renal disease. This case provides a very rare example of a solitary pulmonary nodule as clear cell carcinoma. The patient showed no evidence of recurrence or metastasis after three years postoperatively.

Akciðer berrak hücreli tümörü nadir bir benign tümördür. Akciðer grafisinde pulmoner nodül saptanan 60 yaþýnda erkek hastayý burada sunduk. Akciðer bilgisayarlý tomografisi (BT)’nde sol akciðer üst lob anterior segmentte lokalize 2x2x1,5 cm çapýnda soliter nodül saptandý. Hastaya lobektomi uygulandý. Patoloji incelemesinde berrak sitoplazmalý poligonal hücreler izlendi ve tümör hücreleri HMB-45 ve NSE pozitif boyandý. Tüm vücut PET/CT incelemesinde renal hastalýða rastlanýlmadý. Bu olgu clear cell carcinoma olarak soliter pulmoner nodülün çok nadir örneðini göstermektedir. Hasta operasyondan 3 yýl sonra rekürens ya da metastaz göstermemiþtir.
