Abstract
Spindle cell carcinoma is a relatively rare sarcomatoid tumor occurring often in the oral cavity, lower lip, tongue, floor of mouth and others. Also it has been reported that the patients with chronic renal failure on long-term dialysis have high incidence of neoplasms.
We experienced a case of spindle cell carcinoma on the right margin of the tongue. The patient was a 40-year-old male, who was under artificial dialysis for 4 years because of chronic renal failure.
He found a lump on the right margin of the tongue in August, 1990. He was examined by an internist while beeing treated by artificial dialysis, and then he visited our clinic complaining of a mass on the right margin of the tongue on August 7 th, 1990.
At the first examination, clinical findings revealed a mass of pedunculated polyp measuring about 17mm in diameter on the right margin of the tongue.
On August 23rd, 1990, extirpation of the mass was carried out under local anesthesia on ambulation. The histological diagnosis was spindle cell carcinoma. So tegafur encapsulated with slow-releasing granules (Sunfural S®) was administered per os and then we performed partial excision of the tongue under general anesthesia on September 14th, 1990.
There is no evidence of recurrence nor metastatic findings in the patient 9 months after the operation.
