Synonym(s): radial scar
Any of a group of breast lesions which can mimic invasive carcinoma by physical exam, radiology, gross exam and microscopic exam. The lesions are small, stellate by gross and low-power microscopy and characterised by central fibrosis—usually with an elastotic core and varying amounts of epithelial proliferation and distortion. Microcalcifications can be seen
