Calcificações malignas da mama: correlação mamografia-anatomia patológica

Abstract

Neste trabalho foram realizados 30 estudos de correlação entre os achados da mamografia e da anatomia patológica em 29 pacientes com tumores malignos na mama, cujas mamografias apresentaram calcificações relacionadas com as lesões. Os objetivos principais foram: verificar se as formas das calcificações corresponderam a tipos específicos de tumores e se as formas das calcificações estavam relacionadas aos locais onde eram formadas. Foram estudados dois aspectos objetivos das calcificações identificados nas mamografias: forma e distribuição. Este estudo concluiu que os carcinomas tipo comedo tiveram elevada freqüência de calcificações pleomorfas (95,5%) e padrão de distribuição ductal em 66,5% dos casos. Os carcinomas tipo cribriforme, quando não associados ao tipo comedo, evidenciaram somente calcificações arredondadas em 66,5% dos casos e predominância de distribuição indefinida (78,5%). Os tumores micropapilares, quando não associados ao tipo comedo, mostraram somente calcificações arredondadas em 66,5% dos casos e predominância do padrão de distribuição indefinido (66,5%). Nenhum tumor mostrou padrão de distribuição lobular. Calcificações amorfas na ausência de nódulo tumoral são suspeitas de carcinoma ductal infiltrante. De acordo com o padrão histológico arquitetural dos 30 tumores, 24 (80%) tiveram calcificações com as formas esperadas.
