Os autores apresentam um caso de extenso angiossarcoma do couro cabeludo submetido a radioterapia exclusiva, pela associação de roentgenterapia de ortovoltagem e braquiterapia de alta taxa de dose utilizando um molde. Descrevem os aspectos clínicos, técnicos e a evolução terapêutica. Destacam as particularidades e a utilidade da braquiterapia de alta taxa de dose, nesta situação em particular, e fazem uma análise comparativa das dificuldades e limitações caso a braquiterapia de baixa taxa de dose fosse empregada. Concluem ser a braquiterapia de alta taxa de dose uma opção útil, prática e segura para as lesões neoplásicas superficiais do escalpe, podendo ser considerada uma alternativa ao tratamento com elétrons.

Angiossarcoma de couro cabeludo.Combination of high-dose rate brachytherapy and external beam radiotherapy for the treatment of advanced scalp angiosarcoma -case report. The authors report a case of a patient with an extensive angiosarcoma of the scalp that was submitted only to radiotherapy with a combination of orthovoltage roentgentherapy and high-dose rate brachytherapy, using a mould. The clinical and technical features as well as the therapeutic outcome are presented, and the usefulness and peculiarities of high-dose rate brachytherapy for this particular indication is discussed. A comparative analysis of the difficulties and limitations of employing low-dose rate brachytherapy is also presented. The authors concluded that high-dose rate brachytherapy might be an useful, practical and safe option to treat neoplastic lesions of the scalp, and an alternative treatment to electrontherapy. Key words: High-dose rate brachytherapy. Mould. Scalp angiosarcoma.
ResumoAbstract apresentavam SPM, e destes, apenas 26 eram angiossarcomas(1) . Em 50% dos casos os angiossarcomas acometem regionalmente a cabeça e o pescoço, porém podem ser encontrados em qualquer região do corpo. São tumores agressivos, com alta taxa de recorrên-cia local e capacidade de metastatização, e quando esta ocorre, o pulmão é o sítio preferencial (1,2)
