Sclerosing mucoepidermoid carcinoma (SMEC) has been rarely documented, and previously reported cases have suggested that this histologic variation is basically low-grade with a favorable prognosis. In an earlier report on the firstdescribed intraoral case of SMEC of intermediate grade that recurred as a nonsclerosed, high-grade tumor 13 years after the initial surgery, we presented a primary gingival tumor that occurred in a 28-year-old man as a non-ulcerated, polypoid, 2-cm mass on the retromolar pad. The present report, which briefly summarizes the further clinical course of that case, clearly demonstrates that stromal sclerosis is not a permanent feature of SMEC. Although SMEC has not been extensively studied, it is likely that the presence of extensive scar-like areas seems to have no prognostic significance.
