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.

Keywords: Rrenal cell carcinoma, Eendobronchial metastasis

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).
