Ethanol Ablation for Odontogenic myxoma: New alternative of conservative treatment

Odontogenic myxoma is a maxillofacial tumor that is benign in nature. It is characterized by a slow-growing, painless, and site-aggressive behavior. A main feature is that it is not encapsulated so it has high potential of invasiveness and penetration into peripheral tissues. Large lesions may cause extensive compromise of the region. Treatment strategy for Odontogenic Myxoma is still controversial. Radical resection with an appropriate surgical margin is recommended, but emerging evidence has suggested that a more conservative approach will result in less morbidity and adequate results. This report shows a remarkable result on a 16-year-old patient who had a Mandibular Odontogenic Myxoma treated with a conservative approach. Intra-lesional absolute alcohol irrigation was performed during a 5-month period. Considerable volume reduction of the lesion happened which allowed a minimal overall resection. No recurrence was found after a 3 year follow-up.

Angiosarcoma metastásico de la cavidad oral: a propósito de un caso / Metastatic angiosarcoma of the oral cavity: report of a case

El angiosarcoma oral es un tumor endotelial raro que, debido a su presentación clínica, requiere ser comparada con varias lesiones similares como diagnóstico diferencial. Presentamos un paciente de 66 años en tratamiento por múltiples episodios hemorrágicos digestivos, derivada al Servicio de Cirugía Oral y Maxilofacial del Hospital de Carabineros de Santiago de Chile debido a la presencia de lesiones vasculares intraorales. Se diagnostican inicialmente como lesiones metastásicas de un tumor estromal gastrointestinal, siendo el diagnóstico histopatológico final de un angiosarcoma agresivo y diseminado. La presentación clínica de este tipo de lesiones dificulta el diagnóstico definitivo y, en consecuencia, el manejo de este tipo de pacientes. (AU)

Oral angiosarcoma is a rare endothelial tumour that requires to be included as a differential diagnosis of several similar lesions due to its clinical presentation. We present a 66-year-old patient undergoing treatment for multiple digestive bleeding episodes, referred to the oral and maxillofacial surgery service of the Hospital de Carabineros de Santiago de Chile due to the presence of intraoral vascular lesions initially diagnosed as metastatic lesions of a gastrointestinal stromal tumour, with the final histopathological diagnosis being an aggressive and disseminated angiosarcoma. The clinical presentation of these lesions makes the diagnosis and, consequently, the management of this type of patient difficult. (AU)
