- Clinically characterized by a nodular swelling that leads to a painful craterlike ulcer, 1–5 cmin diameter, with an irregular, ragged border .
- The lesion mimics a carcinoma, and is usually located on the posterior palate.
- Men are affected approximately twice as often as women.
Laboratory tests Histopathological examination.
- Squamous-cell carcinoma,
- mucoepidermoid carcinoma,
