Lesiones papilares malignas de la mama: nuestra experiencia / Malignant papillary lesions of the breast: our experience

Objetivo Este trabajo tiene como objetivo evaluar las características de las lesiones papilares malignas diagnosticadas en una obra social durante el período que abarca desde marzo de 2007 hasta agosto de 2015. Material y método Se realizó un análisis retrospectivo descriptivo de corte trasversal donde se incluyeron 56 pacientes con diagnóstico de Carcinoma ductal in situ papilar (cdis papilar), Carcinoma papilar encapsulado y Carcinoma papilar invasor. Se evaluaron las características clínicas, imagenológicas y anatomopatológicas. Conclusiones Las lesiones papilares malignas representan un desafío para el diagnóstico y manejo del equipo tratante dada su baja frecuencia y constante revisión de criterios diagnósticos y de manejo posterior

Objective The aim of the current study is to evaluate the characteristics of malignant papillary lesions diagnosed during march 2007 through agost 2015. Materials and method Retrospective and descriptive analysis has been made incluiding 56 patients with pathological diagnostic of papillary dcis, encapsulated carcinoma and invasive papillary carcinoma. We analyzed clinical characteristics, form of presentation in radiological features and pathological findings. Conclusions Papillary lesions of the breast represent a challenge for diagnostic an clinical management for clinicians involved, due to low frequency and a lack of clinical guidelines

An unusual case of invasive papillary carcinoma of the breast.

Invasive papillary carcinoma is a rare variant of breast cancer. We report an unusual case of invasive papillary carcinoma of the breast with high nuclear grade, brisk mitosis, necrosis, extensive apocrine differentiation, and intense lymphoplasmacytic infiltrate; additionally triple-negativity for estrogen and progesterone receptors and Her2 neu. The patient underwent modified radical mastectomy and adjuvant chemotherapy. But, it was a node negative breast carcinoma. Increasing the awareness of this clinicopathologic entity would be helpful in avoiding overtreatment of patients with this cancer even if the tumor has negative morphological and immunohistochemical prognosticators.
