Background A diagnosis of non-classic lobular carcinoma in situ (NC-LCIS) encompasses a
variety of lesions with poorly characterized natural history. We evaluated upgrade rates and …

Background Studies report low upgrade rates following excision for classic-type lobular
carcinoma in situ (LCIS) with radiologic-pathologic concordance. Thus, in the absence of …

Background The surgical management of lobular in-situ neoplasia (LN) identified by core
needle biopsy (CNB) is currently variable. Our institution has routinely excised LN on CNB …

This review reflects a collaboration between the American Registry of Pathology (the
publisher of the Armed Forces Institute of Pathology Fascicles) and Annals of Diagnostic …

Lobular carcinoma in situ (LCIS) is considered a risk factor for development of invasive
carcinoma (IC). Many variants of LCIS have been described based on pathologic features …

Context.—Differentiating ductal carcinoma in situ (DCIS) from lobular carcinoma in situ
(LCIS) on core biopsy has important clinical implications. Lobular carcinoma in situ variants …

Background Based on modern series demonstrating low upgrade rates for pure lobular
neoplasia (LN) diagnosed on core needle biopsy (CNB), our institution no longer …

Background The natural history of lobular carcinoma in-situ (LCIS) suggests that women are
at increased risk of subsequent invasive breast cancer. Questions of effective management …

Management of classic lobular neoplasia (cLN) diagnosed on core needle biopsy (CNB) is
controversial. Our aim in this study was to review cases of cLN diagnosed on CNB to …

Lobular carcinoma in situ (LCIS) is a risk factor and a nonobligate precursor of breast
carcinoma. The relative risk of invasive carcinoma after classic LCIS diagnosis is …
