Metastatic renal cell carcinoma to the condyle of the mandible

A 59-year-old woman who had left nephrectomy because of renal cell carcinoma (RCC) 3 years ago referred with trismus and a mass on her left temporomandibular joint. Computed tomography scan revealed an expanding lytic lesion on the left condyle of the mandible. Incisional biopsy was carried out. Histopathologic diagnosis was metastatic clear cell variant of RCC. Metastasis of RCC to the condyle of the mandible has not been reported yet. In this study, we presented a case of RCC metastasis to the condyle of the mandible.
