Description
Summary:Metastases to the breast from an extra-mammary malignancy are extremely rare. Lymphomas and melanomas are the most commonly reported secondary tumors in the breast. Breast metastasis from an esthesioneuroblastoma is extremely rare and only 3 cases are described in the literature. We herein report another case of 31 year-old woman diagnosed with an esthesioneuroblastoma since two years, who presented to our hospital for a breast rapidly growing mass in the right upper inner quadrant. On physical examination, this mass measured 3cm, was firm with no skin retraction and no nipple discharge. Imaging features revealed multiples nodules with irregular border. A fine needed biopsy was performed. On pathological examination, the tumor was arranged in nests and lobules of monotonous tumor cells with round nuclei, indistinct nucleoli and scanty cytoplasm. On immunohistochemistry, the tumor cells were positive for chromogranin. Estrogen and progesterone receptors were negative as well as mammaglobin. Based on the pathological features and clinical history in conjunction with the immunohistochemical finding, the diagnosis of a metastasis of the esthesioneuroblastoma to the breast was made. Our case highlighted the importance of clinical history and imaging features when dealing with a breast lump. La metástasis en la mama de tumores extramamarios son muy poco frecuentes. La metástasis más frecuente es seguida de la leucemia, melanoma y linfoma. La metástasis mamaria de un estesioneuroblastoma olfatorio (ENO) es excepcional, encontrando en solo tres casos publicados. Presentamos un nuevo caso de metástasis en mama de un estesioneurbolastoma olfatorio con una revisión de la literatura. Paciente de 31 años con antecedentes de un ENO diagnosticada hace dos años tratada previamente con radiación y cirugía. La paciente refiere la aparición de una tumoración en el cuadrante superior de la mama derecha, de crecimiento progresivo e indoloro, apareció en el post-parto. A la exploración clínica se identifica dicha tumoración en el cuadrante superior interno de 3 cm de diámetro máximo y consistencia firme, sin alteraciones cutáneas ni del complejo aréola-pezón. La mamografía muestra numerosas zonas, mal delimitadas, de la mama derecha. Se le realiza una punción para biopsia aspiración con aguja fina. En el estudio anatomopatológico reporta una neoplasia neuroendocrina de aspecto uniforme con proliferación de células sin atipia con positividad inmunohistoquímica para cromogranina
