Lobular carcinoma in situ (LCIS) exists as two main subtypes, classic and pleomorphic. While it may sometimes be an invasive cancer precursor, LCIS can be treated as a risk lesion without complete surgical resection. Bilateral mastectomy has been replaced with programs of surveillance. LCIS is ...

Lobular carcinoma "in situ" or lobular neoplasia (Haagensen et al., 1978) is a non-palpable tumor which can only be diagnosed under the microscope (fig. 1 and 2). Histologically, the terminolobular units are densely filled with loosely adherent tumor cells which distend the lobules and ...

Pleomorphic (PLCIS) and florid (FLCIS) lobular carcinoma in situ are rare histologic variants of LCIS that are considered more aggressive than classic LCIS (CLCIS), but optimal treatment is controversial. The genetic drivers of these lesions and their clonal relationships to paired CLCIS and ILC...
Lobular carcinoma in situ (LCIS) is considered to be a risk factor for the development of invasive breast carcinoma, but it may also be a non-obligate precursor to invasive lobular carcinoma (ILC). Many LCIS lesions do not progress to ILC, and the molecu
Lobular neoplasia (LN) is an atypical proliferation of small, dyscohesive epithelial cells within the terminal duct lobular unit (TDLU), with or without pagetoid extension and encompasses both lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH). LN is a non-obligate precursor ...
