Fibroid calcification is a lesion formed by the deposition of calcium salts in fibroids due to various reasons. Calcification is a pathological concept that refers to the formation of calcium deposits in an organ or tissue of the body due to local or systemic factors. Calcification is divided into physiological and pathological calcification, with physiological calcification mainly occurring in the bones and teeth, and pathological calcification divided into dystrophic and metastatic calcification. Fibroid calcification belongs to pathological calcification, and both systemic and local causes of calcium salt deposition are possible. Malignant calcification can also occur in malignant breast tumors, and malignant calcification is manifested as pinpoint, clustered calcification or mucoid calcification, and more than 15 of the above calcifications per 1 cm2 are considered malignant. Calcification leading to mammary fibroids needs to be emphasized as having a higher chance of calcification and needs to be clearly diagnosed.
