17
Q

32 year old female patient presents to your office complaining of a right breast that became rapidly painful in the past few days. The pain is mainly in the lower left quadrant of the breast. Biopsy of the breast tissue is performed and shows epithelial hyperplasia with apocrine metaplasia. The mass is lumpy, bumpy, and fairly mobile. What is the likely diagnosis?

A

Fibrocystic change

18
Q

A fibroadenoma is (Painless/Painful)?

A

Painless

19
Q

A fibroadenoma is (Mobile/Non-Mobile)?

A

Mobile

20
Q

25 year old female patient presents to your office complaining of a lump on her right breast. Upon palpation the mass is mobile and pea-shaped. The patient does not report any pain with movement. A mammography is ordered and shows a well-defined solitary mass that has undergone some calcification. What is the likely diagnosis?

A

Fibroadenoma

21
Q

What is the most common benign growth of the breast?

A

Fibroadenoma

22
Q

What is the most common malignancy in women?

A

Breast carcinoma

23
Q

What gene is associated closely with breast cancer development?

A

BRCA

24
Q

What is ductal carcinoma in situ?

A

Malignant proliferation of epithelial cells in the ducts that has not invaded the basement membrane

25
Q

Ductal carcinoma in situ is most often visualized on mammography as _______________________?

A

Calcification

26
Q

What is the most common form of breast carcinoma?

A

Infiltrating ductal carcinoma

27
Q

53 year old female patient presents to your office complaining of a mass on the right upper part of her right breast. The mass is non-mobile, painless, and craggy. A biopsy of the tissue shows a proliferation of poorly differentiated epithelial cells that have not broken through the basement membrane. A mammography shows the presence of dystrophic calcification in the mass. What is the likely diagnosis?

A

Ductal carcinoma in situ

28
Q

What breast cancer is also known as schirrous carcinoma due to increased fibrosis?

A

Infiltrating ductal carcinoma

29
Q

55 year old female patient presents to your office with a mass on the left upper quadrant of her left breast. The mass is poorly defined, craggy, and matted. It is non-mobile upon palpation. Mammography shows multiple small irregular dense masses with extensive fibrosis in the area. Biopsy of the tissue shows nests and sheets of malignant tumor cells. What is the likely diagnosis?

A

Infiltrating ductal carcinoma

30
Q

A

t

31
Q

What is the least invasive way to diagnose cancer such as breast cancer?

Q

Lobular carcinoma is usually clinically silent (TRUE/FALSE)?

A

t

33
Q

What is the feeling of a lobular carcinoma compared to a ductal carcinoma?

A

Soft and fleshy (feels normal) while a ductal carcinoma is hard and craggy

34
Q

Medullary breast carcinoma is a subtype of ______________________________?

A

Invasive ductal carcinoma

35
Q

55 year old female patient presents to your office complaining of a mass on the right upper quadrant of her right breast. A biopsy is performed and the tumor is soft and fleshy with tissue resembling the medulla of the brain (resembles neurological tissue). What is the likely diagnosis?

A

Gelatinous, Older

A

Mucinous carcinoma

38
Q

What is Paget’s disease of the breast?

A

Adenocarcinoma cells that penetrate the epidermis of the nipple and areola presenting as erythema or an eczematous change to the nipple with retraction

39
Q

What is the gross appearance of Paget’s disease of the breast?

A

Peau d’orange or “orange peel” appearance
