ABSTRACT

RESUMEN El dermatofibrosarcoma protuberans (DFSP) es un sarcoma fusocelular de grado intermedio de malignidad con máxima incidencia en adultos entre 20 y 40 años y de localización habitualmente troncular (cabeza, cuello extremidades superiores). Se presentan tres casos de DFSP de localización excepcional a nivel vulvar. Las pacientes fueron tratadas con vulvectomía respetando márgenes de seguridad pero, debido a la idiosincrasia del tumor, presentaron recidivas locales que precisaron de una nueva cirugía. En su posterior seguimiento no presentaron recaídas y se encuentran libres de enfermedad.


ABSTRACT Dermatofibrosarcoma protuberans (DFSP) is an intermediate grade spindle-cell sarcoma with a highest incidence in adults between 20 and 40 years old and a trunk location (head, neck and arms). We introduce three case reports of vulvar DFSP considered unusual because of their location. The patients were conducted a free-margin vulvectomy but, due to the nature of the tumor, local reappearances required a second surgery. In the subsequent follow-up they did not suffer from any tumor relapse and they are currently disease-free.

ABSTRACT

RESUMEN El carcinoma metaplásico de mama es un tipo de cáncer infiltrante que asemeja un carcinoma de alto grado histológico, pero cuya incidencia es muy baja (< 1%). Desde el punto de vista anatomopatológico presenta un componente mixto epitelial y mesenquimal; siendo lo más característico su comportamiento clínico altamente agresivo junto con unas características anatomopatológicas, inmunohistoquímicas concordantes, como son el HER2/neu negativo, los receptores hormonales negativos, el tamaño tumoral grande y el alto grado histológico. Por todo ello, resulta de especial interés conocer esta entidad, con la finalidad de realizar un diagnóstico preciso y llevar a cabo un tratamiento adecuado en estas pacientes. En el presente artículo se presenta la revisión de dos casos clínicos de cáncer de mama metaplásico, diagnosticados y tratados en nuestro Hospital durante el año 2015 y 2018.


ABSTRACT The metaplastic breast cancer is a subtype of an infiltranting breast cancer and it's usually high grade. However it is a rare subtype of cancer (incidence <1%). This cancer has an epithelial and connective tissues, which has an epithelial invasor ductal breast cancer with high grade and sarcomas breast. The main characteristic of the metaplastic breast cancer is their high agressive behavior as clinical as anatomopathological, which immunohistochemical expression is like a triple negative breast cancer. Because of this we consider that their knowledge is very important with the purpose of being diagnosed in women. In this paper it is showed a revision of two cases of metaplastic breast cancer, whose diagnostic and treatment were reported in our Centre.
