Gingival salivary gland choristoma. A case report.

Gingival salivary gland choristoma is an extremely rare disturbance of glandular development. A review of the literature disclosed only 5 reported cases of this entity and 7 gingival salivary gland tumors or alterations. We present a case of this condition present in a 43-year-old female patient, which was found while reviewing casts for the design of a prosthetic appliance. This case suggests that embryonal pluripotentiality of gingival epithelial cells is retained and that development of salivary glands in gingival tissue is feasible. An additional discussion about its histogenesis is presented.
