Aneurysmal Bone Cyst Plus Lesions: A Case Report and a Literature Review

Abstract

The intraosseous osteolytic lesions mainly involving the metaphyseal region of vertebrae and long bones were diagnosed as aneurysmal bone cysts (ABCs). Further, an ABC was known as an ossifying hematoma. It is considered an expanding osteolytic lesion consisting of blood-filled spaces of variable sizes separated by connective tissue septa containing trabeculae of osteoid tissue and osteoclast giant cells. It is frequently reported to involve long bones; however, only 1.9% prevalence is seen in jaw bones. It represents a very small percentage of all non-odontogenic tumors. ABC shows variations in age prevalence and its clinical presentation may be challenging to the surgeon. In addition, ABC may occur in association with other primary bone pathologies like ossifying fibroma, fibrous dysplasia, and giant cell tumor; such entities are known as ABC plus lesions. Here we present a classic case of ABC plus lesion.

A Large Mandibular Anterior Swelling—A Diagnostic Dilemma: A Case Report

“…From a lesion having no symptoms to a painful, expanding, and destructive pattern, ABC exhibits a wide spectrum of clinical characteristics. 20 The majority of the lesions, however, were asymptomatic swellings, which also existed in our case. Female patient having a lesion in the mandibular anterior region is rare that was present in our case.…”

“…For the treatment of cases of aesthetic deformity, loss of continuity of the mandible, and situations with a high risk of fractures, several writers have advocated for prompt restoration of the defect using autogenous grafts. 20 In the present case, segmental mandibulectomy with reconstruction was done.…”

A importância da biópsia incisional para confirmação diagnóstica de cisto ósseo aneurismático: Relato de caso

“…O Cisto Ósseo Aneurismático (COA) é uma lesão benigna que acomete frequentemente mais a mandíbula do que a maxila com predominância de 3:1 (Vale et al, 2005;Boriani et al, 2001;Kiattavorncharoen et al, 2003). Mas geralmente atinge os ossos longos e a coluna vertebral (Vale et al, 2005;Silva et al, 2007;Caubi et al, 2011;Liu et al, 2021;Sonone et al, 2022).…”

“…Comumente apresenta crescimento rápido, destrutivo, osteolítico, expansivo e é composto por espaços vasculares e sinusóides, que são completados por sangue e cobertos por epitélio fibroso (Vale et al, 2005;Silva et al, 2007;Caubi et al, 2011;Liu et al, 2021;Sonone et al, 2022).…”

“…Clinicamente, os cistos ósseos caracterizam-se por um aumento de volume, podendo promover dor, devido à compressão de nervos, além de possíveis parestesias e fraturas patológicas (Vale et al, 2005;Paiva et al, 2011;Chan et al, 2002). Acometem principalmente pessoas por volta da segunda década de vida, além de terem uma pequena predileção pelo sexo feminino (Vale et al, 2005;Silva et al, 2007;Caubi et al, 2011;Sonone et al, 2022;Domenico, 2019;Boriani et al, 2001;Campidelli et al, 2003).
