Breast Pathology Flashcards
What typically benign characteristics does a mucinous or colloid carcinoma demonstrate?
Posterior acoustic enhancement
“Breast within a breast” is a classic characteristic on mammo for what tumor?
Fibroadenolipoma
Normal skin thickness
2mm or less
Highly speculative calcifications is a characteristic typical of what?
Ductal Carcinoma in Situ (DCIS)
Scaling and redness of the nipple, often confused with eczema is:
Paget’s disease if the nipple
May displace the nipple:
Juvenile fibroadenoma
Oil cysts may be the result of
Fat necrosis
The most common abnormality involving the breast is:
Fibrocystic breast changes
Most common metastatic lesion from the breast :
Metastatic Breast Cancer from the other breast
Which tumor originates from the lining of the lactiferous duct?
Papilloma
Medullary Carcinomas are often confused with:
Fibroadenomas
What effect does a benign mass usually have on fibrous planes within the breast?
Benign masses have no effect on adjacent tissue planes
What tumor is always considered invasive breast carcinoma?
Medullary carcinoma
A BIRADS 5 tumor likely to be a carcinoma is:
Highly suggestive of malignancy
Well defined, thick walled lesion with few floating internal echoes and septations may represent:
An inflammatory cyst
Most common post surgical breast complication
Seroma
Phyllodes tumors have a higher likelihood of being malignant when they are greater than
3 cm and exhibit cystic spaces
Which type of breast cancer presents hystologically with its cells infiltrating surrounding tissue in a uniform, linear arrangement
Invasive Lobular Carcinoma
How is DCIS typically discovered?
Microcalcifications on the mammogram
Benign mass characteristics:
Smooth contours and a thin echogenic capsule
Polymastia refers to:
The presence of accessory glandular tissue
Approximately what percentage of breast pathology do fibroadenomas have
50%
What differentiates malignant phyllodes from the benign version?
Patients with Malignant Phyllodes are typically older than patients with benign Phyllodes tumor
Acute infection of the breast occurs most often:
During lactation
What does “secondary primaries” mean?
Breast cancer recurrence
Characteristics of simple cysts
Smooth contour with well defined borders
Cystic lesion less than 2 mm must be watched carefully because:
They are too small to demonstrate all the characteristics of a simple cyst
“Swiss cheese” appearance is a description used for what tumor?
Juvenile papilloma
Tumor characteristics most consistent with malignancy:
Stellar pattern, hypoechogenicity and angular margins
Fat necrosis usually occurs most frequently following breast trauma
True
Which group of invasive breast cancers has the worst prognosis?
Invasive Ductal Carcinoma (NOS)
Approximately what percentage of vascularity do malignant breast masses usually have?
30% (Hypervascular)
LCIS is not considered a true cancer
True
Lipomas are more compressible than fibroadenoma
True
Patient with h/o Burkett’s, multiple palpable masses in the Rt axilla and hypoechoic mass with irregular boarders in the Rt breast is most likely to have:
Breast lymphoma
Which type of breast cancer contains both glandular and non glandular patterns with epithelial or mesenchymal tissue component?
Metaplastic Carcinoma
Micro and macrocystic breast disease makes up approximately what percent of all lesions identified clinically and/or on mammogram?
25%
Most common benign soft tissue tumor of the breast:
Lipoma
Most common type of invasive carcinoma
Invasive Ductal Carcinoma
Galactoceles may be simple or complex in appearance
True
A patient with a breast that does not include a nipple or areola but does contain glandular tissue is said to have:
Athelia
Tubular Adenomas and Fibroadenomas may be differentiated by what ultrasound appearance?
Presence of tightly packed, punctuate calcifications
