Lobular Carcinoma in Situ with Atypical Mass Presentation: a Case Report

Abstract

Lobular carcinoma in situ (LCIS) is associated with an increased risk of breast cancer and accounts for 1 to 2% of all breast cancers. LCIS diagnosis currently remains one of the major identifiable risk factors for subsequent breast cancer development. Imaging methods are becoming increasingly sensitive, and the consequent detection of small lesions and subtle abnormalities increases the chance of detection of in situ and invasive carcinomas, leading to a reduction in mortality. This report describes a case of a palpable complaint with abnormal imaging findings, including a solid LCIS mass.

Resumo

O Carcinoma Lobular in situ (CLIS) está associado a um aumento do risco de câncer de mama e representa 1-2% de todas as neoplasias mama. Atualmente, o diagnóstico de CLIS continua a ser um dos maiores fatores de risco identificáveis para o posterior desenvolvimento de câncer de mama. Os métodos de imagem estão cada vez mais sensíveis, fazendo com que a detecção de pequenas lesões e anormalidade sutis aumentem o risco de detecções de carcinomas in situ e invasivos, levando a diminuição da mortalidade. Neste relato será descrito um caso de queixa clínica palpável com alteração de achados de imagem como massa sólida de CLIS.
