The differential diagnosis of the metastatic axillary lymphadenopathies of breast cancer with which they occur secondary to the Pfizer-BioNTech vaccine against COVID-19, is imperative. In a series of cases, we analyzed the characteristics of unilateral axillary lymphadenopathy in patients after Pfizer-BioNTech vaccination. Axillary lymphadenopathy were observed ipsilateral to the vaccination arm. The axillary ultrasound defined these as reactive and that they disappeared in 3 weeks. The pathological findings were benign. The anamnesis, the place and date of vaccination and the radiological findings, play an essential role to carry out a correct differential diagnosis and follow-up of these adenopathies.
El diagnóstico diferencial de las adenopatías axilares metastásicas del cáncer de mama con las que se producen secundarias a la vacuna de Pfizer-BioNTech contra la COVID-19 es imperioso. Analizamos una serie de casos con las características de las adenopatías axilares unilaterales tras la administración de la vacuna de Pfizer-BioNTech. Se observaron adenopatías axilares homolaterales al brazo de vacunación. La ecografía axilar las definió como reactivas y que desaparecían en 3 semanas. Los hallazgos anatomopatológicos fueron de benignidad. La anamnesis, el lugar y la fecha de vacunación, así como los hallazgos radiológicos, desempeñan un papel esencial para realizar un correcto diagnóstico deferencial y el seguimiento de estas adenopatías.
