lobular carcinoma of breast
Lobular carcinoma of the breast can be divided into in situ and invasive forms. All arise from the acini or terminal ductules of lobule.
It accounts for about 10% of breast carcinomas. It tends to be multifocal - within the same breast - and bilateral in 20 %. Metastases often seed the peritoneum. In situ disease progresses to invasive carcinoma at a rate of 15% over a 20 yr period.
