Surgical Treatment of Aggressive Intraosseous Cavernous Hemangioma in Maxilla Through Surgical Resection.

Hemangiomas are benign vascular lesions characterized by endothelial vascular proliferation and may demonstrate aggressive clinical features. Intraosseous hemangiomas are uncommon and the maxillary location rare, with few cases described in the literature. The treatment of these lesions varies, however they have a better prognosis when a surgical treatment through resection is performed. The aim of this study is to report a case of right maxillary cavernous intraosseous hemangioma treated by surgical resection with previous embolization. The diagnosis was made through incisional biopsy and immunohistochemical examination. An aggressive lesion profile was observed through the Ki67 marker. During surgery, a temporary ipsilateral external carotid artery ligation was performed to minimize possible bleeding. Weber-Fergson surgical access was performed and total surgical resection through hemi-maxillectomy. The patient is stable after 30 months of follow-up without relapses. In suspected cases of intraosseous hemangiomas, accurate diagnosis and total surgical resection of the lesion is essential. The use of therapeutic mammoths that minimize sagging during and after the procedure such as embolization and arteriography should always be performed.

Cisto dermóide sublingual (30 anos de evolução): relato de caso / Subligal Dermoid Cyst ( 30 years Evolution): Case Report

O Cisto Dermóide é uma condição rara em região de cabeça e pescoço, caracterizado por apresentar um epitélio que contém estruturas anexas em sua parede, glândulas sebáceas, sudoríparas, folículos pilosos ou unhas. Quando em localização supra-milohióidea, o cisto dermóide pode causar deslocamento ântero-posterior da língua, causando transtornos fonéticos e respiratórios. O seu tratamento é a exérese cirúrgica, sendo a escolha do acesso cirúrgico dependente da localização da lesão e da experiência do cirurgião. Este trabalho descreve os aspectos clínicos, imagenológicos e anatomopatológicos, assim como o tratamento cirúrgico desta patologia e proservação do caso. Paciente, gênero feminino, 36 anos de idade, cursando com lesão em assoalho bucal, decorrendo em elevação da língua, dislalia e disfagia, com 30 anos de evolução. Foi realizada exérese da lesão por acesso intra-oral, com diagnóstico anatomopatológico de Cisto Dermóide... (AU)

Dermoid Cyst is a rare condition in head and neck area, histologically characterized by epithelium containing structures attached on its wall, sebaceous glands, sweat glands, hair follicles or nails. When located in upper-mylohyoid muscle area, the Dermoid Cyst can cause displacement of the tongue, respiratory and phonetic disorders. Its treatment is surgical excision, being the choice of surgical approach related to the lesion location and the surgeon's experience. This paper describes the clinical, pathological and imaging aspects as well as surgical treatment and follow up of this pathology. Female patient, 36 years old, showing lesions on the mouth floor, elevation of the tongue, dyslalia, dysphagia and 30 years of evolution. Excision of the lesion was performed by intraoral access, with histopathological diagnosis of Dermoid Cyst... (AU)
