PURPOSE: To review outcomes of lesions diagnosed at core-needle breast biopsy as atypical lobular hyperplasia (ALH) or lobular carcinoma in situ (LCIS). MATERIALS AND METHODS: Results from 1,400 consecutive core-needle breast biopsies were reviewed. Twenty-five (1.8%) biopsy samples with the diagnosis of lobular neoplasia (15 with ALH and 10 with LCIS) adjacent to or in a targeted benign

Lobular neoplasia including lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) may be identified in breast core needle biopsies as incidental findings or associated with microcalcifications.

The most common forms of lobular neoplasia are atypical lobular hyperplasia (ALH) and lobular carcinoma in situ (LCIS). ‘In situ’ means the changes only occur in the breast lobules and do not affect the surrounding breast tissue. You may hear ALH and LCIS referred to as ‘classical lobular neoplasia’.

Hyperplasia is a term used when there is growth of cells within the ducts and/or lobules of the breast that is not cancerous. Normally, the ducts and lobules are lined by 2 layers of cells. Hyperplasia means that there are more cells than usual and they are no longer lined up in just the 2 layers.

Hyperplasia happens when there’s an increase in the number of cells lining the ducts or lobules of the breast. When hyperplasia occurs in the ducts it’s called ductal hyperplasia. Proliferative breast disease: another name for ductal or lobular hyperplasia that affects the breasts Focal epithelial hyperplasia (also known as Heck’s disease) : affects the inside of the mouth or throat in the mucous tissues; can cause a wart or growth and might be triggered by the human papillomavirus (HPV) The most common forms of lobular neoplasia are atypical lobular hyperplasia (ALH) and lobular carcinoma in situ (LCIS). ‘In situ’ means the changes only occur in the breast lobules and do not affect the surrounding breast tissue. You may hear ALH and LCIS referred to as ‘classical lobular neoplasia’. Se hela listan på en.wikipedia.org Atypical hyperplasia and lobular carcinoma in situ are rare proliferative breast lesions, growing inside ducts and terminal ducto-lobular units. They represent a marker of increased risk for breast cancer and a non-obligate precursor of malignancy.

It doesn’t usually cause any symptoms, such as a lump or pain, and is usually found by chance.

LCIS >=50% of TDLU is involved. Atypical lobular Lobular neoplasia refers to the presence of these cells within the terminal ductal lobular unit, with or without pagetoid extension along terminal and segmental ducts. . Lobular neoplasia includes atypical lobular hyperplasia and lobular carcinoma in situ (LCIS), which are distinguished by the degree and extent of lesional involvement of the terminal ductal lobular Sclerosing lobular hyperplasia is an infrequent benign lesion of the breast, defined as prominent hyperplasia of the lobules with sclerosis of the interlobular stroma.

Lobular neoplasia refers to the presence of these cells within the terminal ductal lobular unit, with or without pagetoid extension along terminal and segmental ducts. Lobular neoplasia includes atypical lobular hyperplasia and lobular carcinoma in situ (LCIS), which are distinguished by the degree and extent of lesional involvement of the terminal ductal lobular unit. Atypical hyperplasia (AH) of the breast, which is a diagnostic category of proliferative disease with atypia that includes atypical ductal hyperplasia (ADH) and atypical lobular hyperplasia (ALH), is associated with an increased risk for the subsequent development of carcinoma. 1-3 The risk applies to both breasts, and the majority of cancers develop in the ipsilateral breast.

Selective estrogen receptor modulators (SERMs) and aromatase inhibitors (AIs) can lower risk of subsequent invasive carcinoma in patients with atypical hyperplasias (atypical lobular hyperplasia or atypical ductal hyperplasia not separated) (J Natl Compr Canc Netw 2018;16:1391)

It is therefore considered a part of borderline breast disease. Clinical presentation It is usually Atypical hyperplasia and lobular carcinoma in situ are rare proliferative breast lesions, growing inside ducts and terminal ducto-lobular units. They represent a marker of increased risk for breast cancer and a non-obligate precursor of malignancy. Evidence available on diagnosis and management is scarce.

No lobular unit completely fulfils the extent of involvement required for LCIS No lobular units show complete filling of all the acini, OR Even if all filled, fewer than half of the acini in the lobule expanded There is no category of non-atypical lobular hyperplasia Atypical lobular hyperplasia means that abnormal cells are in a breast lobule (the milk-making parts of the breast). Another high-risk lesion is lobular carcinoma in situ (LCIS), which is more extensive involvement of atypical cells in the breast lobules.
