Summary:Papillary endothelial hyperplasia (PEH) or Masson's tumor is a rare benign vascular tumor that usually appears in the soft tissues of the head and neck, trunk and extremities, being extremely rare in the breast. Its diagnosis can be a challenge, especially in the follow-up of patients with previous disease of breast carcinoma. We present the case of a 65-year-old patient, with a history of bilateral breast cancer and reconstruction with implants, who presented a Masson's tumor during follow-up. An ultrasound scan was performed, showing a well-circumscribed mass in the left breast, located in the posterior contour of the implant. Subsequently, magnetic resonance imaging (MR) depicted an enhancing tumor, without infiltration of adjacent structures. Finally, the definitive anatomopathological diagnosis was obtained after surgical excision. La hiperplasia papilar endotelial (HPE) o tumor de Masson es un tumor vascular benigno poco frecuente, que suele aparecer en las partes blandas de la cabeza y el cuello, tronco y extremidades, siendo excepcional la localización en la mama. Su diagnóstico puede ser un reto, especialmente en el seguimiento de pacientes oncológicos. Presentamos el caso de una paciente de 65 años, con antecedente de cáncer de mama bilateral y reconstrucción con prótesis, que presentó un tumor de Masson en una revisión. Se realizó una ecografía donde se visualizó en la mama izquierda una masa de bordes bien delimitados, localizada en el contorno posterior de la prótesis. Se completó el estudio con resonancia magnética (RM) que mostró un realce intenso del tumor, sin invasión de estructuras vecinas. Tras la intervención quirúrgica se obtuvo el diagnóstico anatomopatológico definitivo.
