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

Is Further Diagnostic Surgery Necessary for the Benign Papillary Lesions that Are Diagnosed by Large Volume Vacuum Assisted Breast Biopsy? / 한국유방암학회지

PURPOSE: There is ongoing controversy regarding the management of papillary lesions that are diagnosed by core needle biopsy (CNB). The development of vacuum assisted biopsy now permits non-operative removal of papillary breast lesions. Our aim was to evaluate whether the papillary lesions diagnosed by vacuum assisted breast biopsy (VABB) can be followed up without further diagnostic excision. METHODS: From January 2003 to July 2009, a total of 4,655 US-guided mammotome excision were performed in 3,714 patients at Kangnam CHA Hospital. Out of 4,655 lesions, 156 lesions were proved to be papillary lesions. Among these, 82 lesions that had histologic findings that were consistent with benign papillary lesions and that were followed up for more than 2 years without further diagnostic surgical excision were collected and retrospectively analyzed. Ultrasonographic follow-up was done at 3-6 month intervals to assess for recurrence. The mean follow up period was 49.6 months. RESULTS: The pathologic diagnoses for the 82 lesions obtained via VABB were benign intraductal papilloma and papillomatosis. Half of the lesions were palpable and 50.0% (41 cases) were nonpalpable. Twenty eight lesions (34.1%) were classified as BIRADS category 3, 50 lesions (61.0%) were category 4A, 3 lesions (3.7%) were category 4B and only 1 lesion (1.2%) was category 5 according to the ultrasound exams. No local recurrence developed during the follow up period that needed surgical re-excision or rebiopsy. None of those diagnosed as benign lesions at VABB were upgraded to a more advanced lesions. CONCLUSION: The benign papillary lesions that are diagnosed and excised by mammotome may not need further diagnostic surgical re-excision if surgeons are sure that the targeted lesions were excised completely.
