Lobular carcinoma in situ (LCIS) is an incidental microscopic finding with characteristic cellular morphology and multifocal tissue patterns. The condition is a. Lobular carcinoma in situ (LCIS) represents the next step up from atypical lobular hyperplasia (ALH) along the malignant spectrum of lobular breast carcinoma.

Afonso N, Bouwman D August LCIS may be present in one lobulilllar both breasts, but it usually is not visible on a mammogram. Furthermore, e-cadherinthe transmembrane protein mediating epithelial cell adhesionexhibits loss of expression on LN cells, and P Catenin exhibits cytoplasmic reactivity. Resembles invasive carcinoma but has alveolar pattern of LCIS.

Most groups recommend considering routine breast cancer screening beginning in your 40s. Atypical lobular hyperplasia as a unilateral predictor of breast cancer risk: Unlike ductal carcinoma, lobular carcinoma does not usually form into a hard lobjlillarbut rather a rather a vague thickening of the breast tissue.

Newer evidence is suggesting LCIS may be more of a pre-cancer than we thought. This may be followed by delayed breast reconstruction.

LCIS is often found concurrently with foci of invasive carcinoma and multiple studies have shown, using genetic sequencing techniques, that inn LCIS and ILC share clonal cell populations, or originate from the same line of mutated cells. By mammography, infiltrating lobular carcinoma is identified when a lesion demonstrates asymmetric density.
