Most frequent proliferative lesions of the Buco Maxillofacial Complex
Keywords:
proliferative lesions, pseudotumoral lesions, benign neoplasias.Abstract
Introduction: proliferative lesions are entities that are present in the buccal cavity. Some of them are of traumatic origin and others are neoplasias. Frequently, they are not well diagnosed in the clinical practice because of the similarity that can exist among them.
Objective: to determine the characteristics of the proliferative lesions diagnosed and the coincidences between clinical and histopathological diagnosis
Method: a retrospective study of the biopsies processed during five years in the Department of Oral Pathology of the Faculty of Stomatology of Havana was conducted dealing with age, sex, type of lesion, anatomic location and similarities between the clinical and histopathological diagnosis.
Results: it was found that, of the proliferative lesions, the pseudotumoral ones reported the 18.1 % and the benign neoplasias, the 5.8 %. In the age group 10-19 years, pseudotumoral lesions represented the 7.78 % and the benign neoplasias the 1,78 %. In the group of 60 years or older, pseudotumoral lesions reported the 22.67 % of the total of proliferative lesions. The female sex resulted to be affected by pseudotumoral lesions in a 61,3 % and the benign neoplasias effected the male sex in a 55 %. Fibroepithelial hyperplasia represented the 54.22 % of the pseudotumoral ones, whereas the nevus reported the 8.67 % among the benign neoplasias. The clinical diagnosis of the pseudotumoral lesions matched up a 50.4 % with the histological; for benign neoplasias, the coincidence was 53.2 %.
Conclusions: pseudotumoural lesions predominated on benign neoplasias, with a marked increase in both types of lesions after 40 years. Pseudotumoural lesions predominated in the female sex, whereas the benign neoplasias predominated in the male sex. There was a low coincidence between the clinical and histopathological diagnosis for both types of lesions.
Key words: proliferative lesions, pseudotumoral lesions, benign neoplasias.
