O nasoangiofibroma e um tumor benigno com componente vascular que acomete homens jovens, e tem como principal tratamento a cirurgia. Tem sido descrita a utilizacao de cirurgia endoscopica para a resseccao de tumores em estadios iniciais, sem evidencia de permanencia de restos tumorais ou recidiva da doenca. OBJETIVO: Este estudo tem o objetivo de avaliar a via endoscopica precedida pela embolizacao como meio de tratamento para nasoangiofibroma em estadios II, e um caso selecionado em estadio III...
Abstract:Perivascular neoplasms comprise traditionally glomus tumor and hemangiopericytoma (HPC). Whereas glomus tumor represents a well-defined entity, the existence of HPC as a separate entity has been questioned because a number of neoplasms of different lines of differentiation are characterized
STUDY DESIGN: A case of myopericytoma of the thoracic spine is reported. OBJECTIVE: To report a recently described and extremely rare soft tissue neoplasm in the previously unreported location of the thoracic spine. SUMMARY OF BACKGROUND DATA: Myopericytoma is a recently described soft tissue neoplasm with perivascular myoid differentiation. All cases have been reported in the subcutaneous and superficial soft tissues of the extremities. This represents the first reported case of this unusual le...
Objetivo:Descrever um raro caso de hemangiopericitoma orbital. Metodos: Relato de caso de associacao entre hemangipericitoma orbital e blefaroptose. Resultados: A exerese da neoplasia normalizou o posicionamento palpebral. Conclusoes: Lesoes orbitais anteriores sao causas de blefaroptose por compressao do musculo elevador palpebral. (AU)
The clinicopathologic features of 24 tumors showing perivascular myoid differentiation are described. These included tumors with histologic features of "infantile-type" myofibromatosis occurring in adult patients (8 cases), tumors with composite features of "hemangiopericytoma" and glomus tumor (9 cases), and tumors with a distinctive concentric perivascular proliferation of spindle cells (7 cases). Evidence of morphologic overlap among these groups suggests they are closely related neoplasms th...

Infantile myofibromatosis is a distinctive type of fibromatosis that usually develops during the immediate perinatal period. There are variants with solitary and multiple tumors. Lesions confined to the skin, soft tissue, and bone carry a good prognosis, showing spontaneous regression. The prognosis, however, is much less favorable when visceral lesions are present and the outcome may be fatal. Only recently it became obvious that there is an adult counterpart of infantile myofibromatosis, chara...
