“…EPC is used to define papillary carcinomas, which are well-defined lesions surrounded by a fibrous capsule, that lack myoepithelial cells in the periphery and the papillae ( 4 ). Previous studies have demonstrated that EPC tends to affect elderly women and always presents as a subareolar mass and/or with nipple discharge ( 18 , 19 ).…”

“…Microscopically, similar to other types of papillary intraductal carcinoma, EPCs arise in a cystically dilated duct and lack myoepithelial cells (MECs), both in the fibrovascular cores and at the periphery ( 4 ). The absence of MECs and reported cases of metastatic tumors indicate that these tumors represent low-grade invasive carcinomas with an expansile growth pattern ( 5 ).…”

Encapsulated papillary carcinoma (EPC) is a relatively rare form of breast cancer. To date, no evidence-based guidelines for the treatment of EPC have been established. Between January 2015 and December 2021, patients with histologically confirmed EPC of the breast were recorded in a database by The Third Hospital of Nanchang City (Nanchang, China). A total of 46 patients with EPC were retrieved from the database. Age at diagnosis ranged from 41-88 years (median age, 62 years). A total of 21 of these patients had pure EPC, 6 patients had EPC associated with ductal carcinoma in situ and 19 patients had EPC associated with invasive carcinoma. The majority of EPC cases were low nuclear grade, hormone receptor-positive and human epidermal growth factor receptor-2-negative. Additionally, myoepithelial cells were always absent in the papillae of the EPC. All patients underwent lumpectomy or mastectomy with sentinel lymph node biopsy, and almost all of the patients received adjuvant hormonal therapy. Adjuvant chemotherapy was only suggested to 4 patients who were diagnosed with axillary lymph node involvement. Subsequently, the clinicopathological features of non-invasive EPC were compared with invasive EPC. The results indicated that larger tumor sizes and axillary lymph node metastases were more common in invasive tumors. During the follow-up, only 2 patients with invasive EPC experienced recurrence or metastasis. In conclusion, a substantial proportion of invasive EPC cases display aggressive characteristics and metastatic potential, despite it being considered a subtype of carcinoma in situ with excellent prognosis, and local surgical resection is the initial method of treatment. Therefore, adjuvant endocrine therapy, radiotherapy and chemotherapy should be considered in select patients, especially in those diagnosed with invasive EPC tumors.

“…Sin embargo, la presencia de carcinoma ductal in situ en el tejido adyacente confiere un mayor riesgo de recidiva local, la escisión quirúrgica completa de la lesión, con muestreo extenso de tejido mamario circundante, es esencial para el tratamiento y para la evaluación del riesgo de recurrencia local 6 .…”

En el más reciente número de esta revista se publicó el estudio titulado “Lesiones papilares de mama: estudio clínico-patológico y sobrepronóstico en 144 casos de Medellín, Colombia”, donde se hace un excelente acercamiento sobre este tipo de lesiones. Se conoce que las lesiones papilares de la mama son entidades poco frecuentes en la práctica cotidiana, con una representación del 10% de las entidades benignas y solo un 1% de las entidades malignas. Su manifestación clínica habitual es la secreción serosanguinolenta, unilateral, sin masas palpables y en los estudios de imagen suelen mostrarse como lesiones únicas o múltiples de localización retroareolar. El diagnostico anatomopatologico no es sencillo en estudios por punción, bien sea con aguja fina o por aguja gruesa y, por lo general, se requiere de la escisión de la lesión para obtener un diagnóstico más certero.
