Approximately 15% of renal cell carcinomas metastasize to the head and neck region. Here in, we report a rare case report of a patient who underwent nephrectomy for renal cell carcinoma (RCC) ten years ago and presented with metastatic renal cell carcinoma on her lower lip. A 65-year-old woman presented with a rapidly growing mass on the lower lip. Pathology report resulted in renal cell carcinoma metastasis. Although metastatic renal cell carcinoma to the head and neck is uncommon, metastasis should be considered in the differential diagnosis of a rapidly growing vascular lesion in the head and neck area of patients with renal cell carcinoma.

We report a rare case of advanced metastatic renal cell carcinoma which initially presented to the clinic with back and forehead lumps. Ultrasound imaging of the lumps and later of the abdomen picked up a right renal tumour which led to further computed tomography and bone scans. The bone scan confirmed that the forehead lump was a calvarial metastasis and such a presentation for metastatic RCC is very rare which bears a significantly poorer prognosis.

Renal oncocytomas and retroperitoneal schwannomas are rare and typically benign tumors with characteristic histopathologic features. Ideal management of both renal oncocytoma and retroperitoneal schwannoma is surgical resection. We present a rare case of a 63-year-old man with multifocal renal oncocytoma and retroperitoneal ancient schwannoma which, preoperatively, masqueraded as metastatic renal cell carcinoma. Both tumors were successfully resected surgically. Immunochemistry and histopathology confirmed each diagnosis.
