A review of histopathological and immunohistochemical parameters in diagnosis of metastatic renal cell carcinoma with a case of gingival metastasis
ABSTRACT The oral cavity constitutes a site of low prevalence for metastasis of malignant tumors. However, oral metastasis of a renal origin is relatively more common and represents 2% of all cancer deaths. Renal cancer may metastasize to any part of the body, with a 15% risk of metastasis to the head and neck regions, and pose one of the greatest diagnostic challenges in medical sciences. Approximately 25% of patients have a metastatic disease at initial assessment, which is often responsible for initiating the diagnosis in the first place. Here we present a review of literature of renal cell carcinoma along with a case of gingival metastasis.

ABSTRACT: Primary tumour of the kidney metastasizing to the tongue is very unusual and only anecdotal cases have been reported. An exhaustive literature review covering the period from 1911 onwards disclosed 28 cases. Out of those, only 3 cases presented initially with tongue metastases before the diagnosis of primary renal cell carcinoma.The prognosis for patients with lingual metastasis of renal cell carcinoma is poor. Treatment of tongue metastasis is usually palliative and aims to provide patient comfort by means of pain relief and prevention of bleeding and infection. Surgical excision is recommended as the primary treatment with emphasis on preservation of tongue structure and function. We report a case of tongue metastasis as an initial presentation of renal cell carcinoma in a 78-year-old man. Initially thought to be primary tongue cancer but on review of his histopathology again, it was diagnosed to be a rare metastasis from kidney cancer. Tongue metastasis from renal cell carcinoma is rare and its diagnosis is a challenge. The prognosis of patients with tongue metastasis is poor. Similar to the primary tumours of the tongue, metastatic lesions may be ulcerated or polypoid. Since the tongue is a rare metastatic site, when a lesion is detected, a thorough evaluation to distinguish between metastasis and primary cancer should be made as the management and prognosis vary.Journal of Medical Case Reports 07/2008; 2(2):249.

ABSTRACT: Malignant neoplasms metastatic to the gingivae are rare. Our review of the literature revealed only eight acceptable examples. We are reporting two additional cases. One patient was a 58-year-old man with an adenocarcinoma of the lung which metastasized bilaterally to the maxillary gingiva. The second patient was a 27-year-old man with a synovial sarcoma which metastasized to multiple sites in the maxillary and mandibular gingiva. Clinically, gingival metastatic lesions are most often confused with hemangioma, pyogenic granuloma, giant-cell granuloma, and pepripheral fibroma. They usually occur late in the course of the disease and are associated with metastatic deposits in many other organs and tissues. Death usually occurs in a few weeks or months after discovery of the gingival metastasis.Oral Surgery Oral Medicine Oral Pathology 09/1977; 44(2):238-45. DOI:10.1016/0030-4220(77)90274-2
