Ganglio intramamario metastásico como primera manifestación del cáncer de mama

Intramammary lymph nodes are found in approximately 5% of patients undergoing mammography, regardless of the indication for this procedure. Normal (benign) and enlarged (metastatic, infiltrated) intramammary lymph nodes can usually be differentiated by their mammographic and sonographic appearance, but follow-up examinations or histopathological diagnosis are sometimes needed. Metastatic disease from breast cancer to intramammary lymph nodes affects prognosis and influences therapeutic decisions. The interest of the case presented herein lies in the rarity of metastatic intramammary lymph node as the primary sign of breast cancer. We describe a clinically and radiologically suspicious tumor 2 cm in diameter in the inferior-medial quadrant of the breast, which was a metastatic lymph node from a multifocal invasive carcinoma in this location.
