title: Gingival cyst of the adult: a case report and immunohistochemical investigation.
abstract: A 42-year-old woman had a sessile swelling that involved the maxillary gingiva corresponding to the right canine and premolar area. Clinical examination showed a painless small nodule (10 mm in diameter) located between the right maxillary canine and premolar. The lesion was vesicular, sessile, and slightly compressible on palpation. Microscopic examination of the lesion (following an excisional biopsy) showed cystic spaces covered by an epithelium lining that consisted of cuboidal and squamoid cells intermingled with clear cells. These morphologic findings were consistent with gingival cyst of the adult. Immunohistochemical technique against cytokeratins revealed that the epithelial cells were positive for cytokeratins No. 7, 8, 13, 14, and 19. Two years after removal, no recurrence was reported.
