Carcinoma of the tongue in a long-term survivor of clear cell sarcoma of the kidney.

Squamous cell carcinoma (SCC) of the tongue in persons younger than 30 years of age is an extremely rare neoplasm. We report an unusual case of SCC of the tongue as a second malignancy in a young adult with a history of a stage III clear cell sarcoma of the kidney (CCSK) treated 19 years earlier. Review of the literature reveals a spectrum of cytogenetic abnormalities in SCC; however, aberrations involving the long arm of chromosome 10 have been reported in both SCC and CCSK. Long-term follow-up, with particular attention to the head and neck, may be warranted in children with CCSK.
