    Papillomas of the breast: factors associated with underestimation
    (2018) BOUFELLI, Gabriela; GIANNOTTI, Marcelo A.; RUIZ, Carlos A.; BARROS, Nestor de; CHALA, Luciano E.; MAESAKA, Jonathan Y.; GONCALVES, Rodrigo; BRESCIANI, Barbara H.; VIANNA, Paula; SOARES JR., Jose. M.; BARACAT, Edmund C.; FILASSI, Jose. R.
    The distinction between benign and malignant papilloma of the breast through percutaneous needle biopsy can be difficult because of limited samples; the underestimation rate can be up to 25%. The aim of this study is to identify clinical and histological factors associated with underestimation, invasive ductal carcinoma, or ductal in-situ carcinoma (DCIS) of the breast found in surgical specimens from papillary lesions. This may contribute toward selection of patients for a follow-up strategy without the need for surgical excision. From a database of 3563 patients, we identified 85 with intraductal papilloma between 2007 and 2013 who had undergone breast-imaging studies, percutaneous needle biopsy, and surgical resection of the lesion. Central papillomas normally present with a palpable mass, whereas peripheral papillomas generally do not have clinical manifestations (microcalcifications); both central and peripheral papillomas were related to atypical lesions, 13.5 and 15.4%, respectively. Among the 59 cases of central papillomas, there were four cases of underestimation, three DCIS and one invasive ductal carcinoma (6.8%). Among the 26 cases of peripheral papillomas, there was one case of DCIS (3.8%), with a total underestimation rate of 5.8%; all underestimated lesions measured more than 1cm. The median size was 11mm at mammography and 19mm at ultrasound. Our data suggest that lesions less than 1cm in size, without atypia and concordant imaging and clinical findings, may not require surgical resection.

    Imaging of male breast disease: the good, the bad and the ugly - A pictorial review
    (2020) VIANAA, Marcela Pacheco; TUCUNDUVAA, Tatiana Cardoso de Mello; TORRES, Ulysses S.; AGUILLARA, Vera Lucia Nunes; BRESCIANI, Barbara Helou; SHIMIZU, Carlos; CHALA, Luciano Fernandes; BARROS, Nestor de; MELLO, Giselle Guede Netto de
    The male breast is affected by a broad spectrum of conditions, ranging from benign to malignant, many of which are similar to those occurring in its female counterpart. Despite the challenge motivated by different imaging characteristic features, correct imaging interpretation in male breast disease may aid at differentiation between benign and suspected conditions, narrow the differential diagnosis and guide subsequent management. The purpose of this review is to showcase a wide array of male breast diseases, discuss their imaging presentations and key features for diagnosis.

    Encapsulated Papillary Breast Carcinoma: Anatomopathological and Clinicoradiological Aspects
    (2018) MATSUMOTO, R. A. E. K.; BRESCIANI, B. H.; THOMPSON, B. M.; BARROS, N. de
    Encapsulated papillary carcinoma or intracystic papillary carcinoma of the breast is a rare tumour and is a special subtype of carcinoma. The most relevant histological characteristic is the absence of a myoepithelial cell layer. The lack of such a layer leads to uncertainty in diagnosis and consequent management, depending on whether the tumour is considered an invasive neoplasm or an in-situ neoplasm. This article illustrates the histological characteristics of this subtype of breast cancer, its most common imaging presentation, clinical findings, diagnosis, and treatment.
