Resumo: Soft-tissue keratocyst (STK) of the oral and maxillofacial region is an exceedingly rare cyst of uncertain origin that mainly affects the buccal space of male patients with 52.5 years. Case 1 was of a 44-year-old man with a painful swelling in the left buccal mucosa lasting 3 years with drainage to the oral cavity. Case 2 was of a 74-year-old woman with a painful swelling in the left buccal mucosa of unknown duration. Incisional biopsy was performed, and microscopic evaluation of both cases revealed a cyst lined with a few cell layers composed of columnar palisading basal cells and a corrugated parakeratin surface. The capsule comprised fibrous connective tissue with variable amounts of blood vessels with hemorrhage, nerve bundles, fat tissue, striated muscle fibers, and the absence of pilosebaceous units. No recurrence was observed after complete surgical removal. We report two additional cases of STK from Brazil.
