Renal cell carcinoma (RCC) is the most common malignant lesion of the kidney, accounting for 90-95% of all renal cancers in adult. Approximately, 30% of patients present with metastatic disease at diagnosis, and one-third of the remainder will develop metastasis during follow-up. Presence of distant metastases at diagnosis is a strong independent predictor of poor survival in patients with RCC. RCC metastasizes by haematogeneous and lymphogeneous ways. Pulmonary metastases are common in patients with renal cell carcinoma and usually consist of multiple nodules of varying sizes that develop in both lung fields. In contrast, metastases to the supradiaphragmatic nodes but no pulmonary paranchymal metatases are rare. A 71-year-old male with renal cell carcinoma whom radical nefrectomy and postoperative radiotherapy was performed. After the treatment, computed tomography of the thorax showed the conglomerate lymph node enlargement in subcarinal region. Histology of this lesion was revealed renal cell carcinoma after the broncoscopic biopsy. The present case is discussed in light of the recent literature.

Böbrek hücreli karsinomda mediastinal lenf nodu metastazı: Olgu sunumu ve literatür derlemesi

Öz

Böbrek hücreli karsinom böbreğin en sık görülen malign tümörüdür ve yetişkinlerdeki böbrek tümörlerinin %90-95'ini oluşturur. Tanı sırasında hastaların %30'unda uzak organ yayılımı vardır. Tanı anında uzak yayılım olması kötü prognozun güçlü bir göstergesidir. Yayılım lenf yoluyla ya da kan yoluyla olabilir. Akciğerler, kemikler, karaciğer, lenf nodları ve mediasten en sık yayılım görülen bölgelerdir. Akciğer parankim lezyonları böbrek hücreli tümörlerde sık görülmesine rağmen parankim tutulumu olmaksızın mediastinal lenf nodlarına yayılım nadirdir. Bu yazıda böbrek hücreli karsinom tanılı 71 yaşındaki erkek hasta sunuldu. Radikal nefrektomi ve ameliyat sonrası radyoterapi uygulanan hastanının toraks tomografisinde mediastinal lenfadenopati belirlendi. Olgumuz güncel literatür ışığında tartışıldı.
