Pathologic and clinical follow-up is reported for a series of patients with lobular neoplasia diagnosed on breast core biopsy
Dedicated breast pathologists and radiologists correlated the histologic and radiologic findings
In 13% of patients, excision after a core biopsy diagnosis of lobular neoplasia resulted in upgrade to carcinoma (invasive carcinoma, ductal carcinoma in situ or pleomorphic lobular carcinoma in situ)
Suspicious findings on imaging studies and the extent of lobular neoplasia on core biopsy may correlate with the likelihood of upgrade to carcinoma
