RESUMO

De todas las neoplasias malignas de mama los carcinomas ductales son los más frecuentes. Menos del 5% son denaturaleza metaplásica y 0,04%-0,1% presentan diferenciación de células escamosas, subtipo que se considera más agresivo. Debido a los pocos casos en la literatura,no hay consenso sobre su diagnósticoy tratamiento. Presentamos tres casos con ese diagnóstico vistos entre 2014 y 2015 en nuestra institución y que corresponden a mujeres de 57, 49 y 65 años sin factores de riesgo y que presentaron cuadros clínicos similares consistentes con aparición de masa de crecimiento rápido. Dos de las pacientes se habían diagnosticado previamente con carcinoma ductal infiltrante de tipo no especial en biopsias por tru-cut con diagnóstico definitivo en la mastectomía radical que reportó en todos los casos carcinoma metaplásico escamoso confirmado por inmunohistoquímica.


Ductal carcinomas are the most common of all breast malignancies, less than 5% are of metaplastic nature, and 0.04% to 0.1% have squamous cell differentiation. These special subtypes are considered more aggressive. Due to the few cases in the literature, there is no consensus about its diagnosis and treatment. Three cases are presented with this diagnosis, seen in our institution between 2014 and 2015. They were women of 57, 49, and 65 years old with no risk factors, and who presented with similar clinical features, consisting of the appearance of a rapid growing mass. Two of the patients had been previously diagnosed with infiltrating ductal carcinoma of no special type by core needle biopsy, with a definitive diagnosis in radical mastectomy, which reported squamous metaplastic carcinoma confirmed by immunohistochemistry.
