What percentage of Spiculated breast masses are cancer?
What percentage of Spiculated breast masses are cancer?
For example, a spiculated (or stellate) lesion has a high positive predictive value for malignancy, often around 90%2, whereas a mass with a circumscribed contour most often indicates a benign lesion (e.g. fibroadenoma, cyst or hamartoma)3.
What percent of Spiculated masses are benign?
This is confirmed by this review of the first 8 years of screening in East Sussex where only 3.6% of masses with spiculation were benign at excision (24 out of 668), compared with 33.3% of masses without spiculation (102 out of 306).
Can a Spiculated mass in the breast be benign?
Spiculated breast lesions may be caused by both benign and malignant processes, including sclerosing adenosis, postsurgical scar, radial scar, tuberculosis (rare), posttraumatic oil cysts, infiltrating ductal carcinoma, ductal carcinoma in situ (rare), infiltrating lobular carcinoma, and tubular carcinoma.
What is a malignant lesion in the breast?
Malignant lesions are cancerous in nature and are threatening for the health after a biopsy. They are characterized by progressive and uncontrolled growth. These type of lesions must be removed immediately by a surgery.
What does a Spiculated breast mass look like?
Spiculated masses are defined as masses with lines radiating from their margins (Fig. 1). Lesions classified as non-spiculated were circumscribed, microlobulated, obscured or indistinct (Figs.
What is a lesion on a mammogram?
At mammography, the lesion appears as an irregularly shaped, high-density spiculated or indistinct mass without associated calcifications and is indistinguishable from breast cancer (,18–,20) (,,,Fig 9a).
What causes spiculated lesions on the breast?
Spiculated breast lesions may be caused by both benign and malignant processes, including sclerosing adenosis, postsurgical scar, radial scar, tuberculosis (rare), posttraumatic oil cysts, infiltrating ductal carcinoma, ductal carcinoma in situ (rare), infiltrating lobular carcinoma, and tubular carcinoma.
What causes spicules on a mammogram?
The spicules of benign lesions are often caused by fibrous tissue, lipid-filled spaces surrounded by histiocytes, or sclerotic stroma, whereas the spicules of malignant lesions are due to tumor infiltration, desmoplastic response, or periductal fibrosis. Mammography alone is frequently not reliable for making the specific diagnosis.
What is the most typical mammographic appearance of breast carcinoma?
The majority of breast carcinomas have the mammographic appearance of a radiating structure, either a definite stellate/spiculated lesion or architectural distortion with no central tumor mass. The most typical mammographic appearance of breast carcinoma is a stellate lesion, i.e. a solid central tumor mass surrounded by a radiating structure.
What do radradial scars look like on mammography?
Radial scars vary in appearance from one mammographic projection to the other. Each view may thus give a somewhat different picture. A similar mammographic appearance can occasionally be seen in traumatic fat necrosis (Case 68).
