Abstract
in English, Spanish

Mucinous carcinoma of the breast is a rare histological type, which represents between 1 and 4% of breast cancers. Treatment does not differ from other histological types, and it occurs more frequently in older adult women. Prognosis is good. We report the case of a 72-year-old patient with a 1-year disease course characterized by the appearance of a slow-growing tumor in the left upper quadrant of the left breast, in which the core biopsy showed mucinous breast carcinoma of a low nuclear grade. The patient underwent quadrantectomy plus a sentinel node biopsy, which confirmed the initial diagnosis.

El carcinoma mucinoso de la mama es un tipo histológico raro, que representa entre el 1 y el 4% de los cánceres de mama. Su tratamiento no difiere de los demás tipos histológicos. Se presenta con mayor frecuencia en mujeres adultas mayores y se distingue por un buen pronóstico. En este artículo, se reporta el caso de una paciente de 72 años, con tiempo de enfermedad de un año, caracterizado por la aparición de una tumoración de crecimiento lento y progresivo en el cuadrante superior externo de la mama izquierda, a la cual se realizó biopsia core. La biopsia arrojó un resultado de carcinoma mucinoso de mama, con grado nuclear bajo. La paciente fue sometida a cuadrantectomía más biopsia de ganglio centinela, lo cual confirmó el diagnóstico inicial.

Keywords: mucinous carcinoma; breast cancer.
