“…The main histological subtypes of RCC are clear cell, papillary, chromophobe, collecting duct carcinoma, medullary carcinoma and unclassified [ 6 ]. Distinction between clear cell salivary tumours and RCC should be made prior to treatment, as histologically, this can be difficult to perform on standard light microscopy.…”

Tongue metastasis of renal cell carcinoma (RCC) are rare, with 90% of malignant lesions in the oral cavity consisting of squamous cell carcinoma (SCC). There are a number of subtypes of SCC which need to be considered as well as rarer pathology and even benign conditions. The case involves a 63-year-old gentleman with an incidental finding of pulmonary metastasis from a RCC of the left kidney, and he concurrently had a RCC deposit on the dorsum of the tongue, which was diagnosed after biopsy. Treatment modalities of surgical excision, radiotherapy and systemic therapy are considered, but with such a poor prognosis with disseminated disease, options are limited. Treatment should include multidisciplinary team input, with a focus on reducing disease morbidity.

“…The main histological subtypes of RCC are clear cell, papillary, chromophobe, collecting duct carcinoma, medullary carcinoma, and unclassified [ 24 ]. Unclassified RCC represents approximately 4 to 6% of all RCCs and are classified as high-grade lesions, characterized by the presence of a sarcomatoid component without any recognized epithelial elements [ 25 ].…”

“…Unclassified RCC represents approximately 4 to 6% of all RCCs and are classified as high-grade lesions, characterized by the presence of a sarcomatoid component without any recognized epithelial elements [ 25 ]. The sarcomatoid is a tumor differentiation which may coexist with any histologic subtype of RCC [ 24 ], and the presence of sarcomatoid elements is associated with an aggressive disease course [ 24 , 26 ]. Our patient had a high-grade unclassified RCC with a sarcomatoid component in the biopsy of the tongue lesion.…”

Lingual metastasis as an initial presentation of renal cell carcinoma: a case report

et al. 2017

BackgroundRenal cell carcinoma is the third most common tumor that metastasizes to the head and neck, after breast and lung carcinomas. Tongue metastasis as an initial presentation of renal cell carcinoma is extremely rare, and very few cases have been reported. The prognosis is poor. We present a rare case of metastatic renal cell carcinoma that initially presented as a tongue lesion.Case presentationWe report the case of a 55-year-old white man who presented with a large exophytic lesion on his tongue. A biopsy was taken, and pathologic examination showed a poorly differentiated carcinoma including a sarcomatoid component. Subtotal glossectomy with neck dissection were planned, but a positron emission tomographic-computed tomography scan showed a left kidney mass. Immunohistochemical evaluation of the tongue lesion was performed, and it was compatible with metastasis from primary renal cell carcinoma. The biopsy of the renal lesion showed a high-grade unclassified renal cell carcinoma. Although our patient underwent systemic therapy, he died of hemorrhagic complications 3 months after the initiation of therapy.ConclusionTongue lesions require a complete assessment to distinguish a metastasis from a primary cancer in order to give the appropriate treatment.
