Teacup calcifications, also known as the "teacup sign," are a specific radiologic sign indicative of benign breast conditions, particularly milk of calcium within cysts. [1] These calcifications exhibit a distinctive appearance on mammography, helping radiologists in distinguishing benign entities from malignant ones.
When consisting of calcium phosphate, they are usually dystrophic calcifications (occurring in degenerated or necrotic tissue). [3] Yet, the mechanism of their formation is not fully known. [4] Calcium oxalate crystals in the breast may be seen on mammography and are usually benign, but can be associated with lobular carcinoma in situ. [5]
Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation.
They found that women with breast arterial calcification seen on mammography were at an increased risk of stroke, cardiovascular death, atherosclerotic cardiovascular disease and congestive heart ...
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
Collagenous spherulosis is characterized by a tubular/cribriform architecture with intratubular eosinophilic material that classically is arranged like the spokes of a wheel ("radial spikes"). There is usually no mitotic activity, and two cells populations (epithelial & myoepithelial) are present, like in benign breast glands.
Stereotactic biopsy, also known as stereotactic core biopsy, is a biopsy procedure that uses a computer and imaging performed in at least two planes to localize a target lesion (such as a tumor or microcalcifications in the breast) in three-dimensional space and guide the removal of tissue for examination by a pathologist under a microscope.
Atypical ductal hyperplasia (ADH) is the term used for a benign lesion of the breast that indicates an increased risk of breast cancer. [1]The name of the entity is descriptive of the lesion; ADH is characterized by cellular proliferation (hyperplasia) within one or two breast ducts and (histomorphologic) architectural abnormalities, i.e. the cells are arranged in an abnormal or atypical way ...
