Abstract

A distant metastasis from a renal cell carcinoma is quite common after a radical nephrectomy. For this reason, a5 year scheduled follow up is recommended. However, a distant metastasis 5 years after the resection is quite rare. We encountered an endobronchial metastasis from a renal cell carcinoma that was discovered 7 years after the radical nephrectomy, and did not present during the 5 year scheduled follow up regimen. We report this case with a review of the literatures.

Figure

• 

  Figure 1 Chest radiograph shows right infrahilar mass-like opacity and Dense pneumonic infiltrates at lower portion of right middle lobe and lower lobe.

• 

  Figure 2 Chest CT scan shows endobronchial mass(arrow) in the right intermediate bronchus(A) and obstructive pneumonitis through right middle and lower lobes(B,C).

• 

  Figure 3 Bronchoscopic finding shows endobronchial mass obstructing right intermediate bronchus.

• 

  Figure 4 On cut section along the bronchial tree, a yellowish tan multilobulated firm mass is seen just beneath the bronchial mucosa.

• 

  Figure 5 On microscopic examination the tumor cells having clear cytoplasm with distinct cell membrane and uniform nuclei form alveolar or solid nests in the thin capillary network (A). The patient's renal cell carcinoma which was diagnosed 7 years ago (B) show similar findings(H & E stain, ×100).
