Hamartomas e coristomas dos tecidos moles de cavidade bucal: série de casos e revisão da literatura

Abstract

Oral soft tissue-derived hamartomas and choristomas are relatively uncommon lesions, being more prevalent in childhood. They present themselves as self-limited growths that are proper and ectopic to the site of origin. OBJECTIVES: To investigate clinical parameters, demographic data, diagnostic imaging, and histopathological features of oral soft tissue-derived hamartomas and choristomas. METHODS: Oral hamartomas and choristomas cases diagnosed between 1987 and 2022 were retrospectively retrieved from the School of Dentistry’s Pathology Laboratory at the Federal University of Uberlândia. A review of case reports published in the literature was also performed, analyzed and compared to our casuistic. RESULTS: The retrospective analysis of the 15 cases gathered showed a slight predilection for females and affected a wide range of age, from newborns to 68 years old. Clinically, the lesions presented as small nodules, similar in color to the mucosa, variable in location and painless. The diagnosis of hamartomas was observed in 60,00% of cases, while choristomas in 40,00%. CONCLUSION: Recognizing the general characteristics of oral soft tissue-derived hamartomas and choristomas is essential to guide the correct diagnosis and therapeutic management of these lesions, avoiding invasive treatments that contradict their benign nature.
