  • Breast Cysts
    Beaumont Hospital Patient Information on Breast Cysts PRINTROOM PDF 23012017 SUP190B What are breast cysts? The breasts are made up of lobules (milk- producing glands) and ducts (tubes that carry milk to the nipple), surrounded by fatty and supportive tissue. Sometimes fluid-filled sacs develop in the breast tissue. These are breast cysts. It’s thought that they develop naturally as the breast ages and changes. Although you can develop breast cysts at any age, they are most common in women over 35 who haven’t yet reached menopause. They occur more frequently as women approach the menopause and usually resolve or are less frequent after it. However, they may persist or develop in women who take hormone replacement therapy (HRT) after menopause. Cysts can feel soft if they are near the surface of the skin, or like a hard lump if they’re deeper in the breast tissue. They can develop anywhere in the breast, but are more commonly found in the upper half. For some women cysts can feel uncomfortable or even painful. Before a period cysts may become larger, and feel sore and tender. It’s common to develop one or more cysts either in one breast or both breasts –and this is nothing to worry about. It is also common to have many cysts without knowing about them. How are they found? Cysts usually become noticeable as a lump in the breast, or are sometimes found by chance when you have a breast examination or routine mammography. When you have a breast examination your GP will sometimes be able to say whether the lump feels like a cyst.

  • Approach to Breast Mass
    APPROACH TO BREAST MASS Resident Author: Kathleen Doukas, MD, CCFP Faculty Advisor: Thea Weisdorf, MD, CCFP Creation Date: January 2010, Last updated: August 2013 Overview In primary care, breast lumps are a common complaint among women. In one study, 16% of women age 40-69y presented to their physician with a breast lesion over a 10-year period.1 Approximately 90% of these lesions will be benign, with fibroadenomas and cysts being the most common.2 Breast cancer must be ruled out, as one in ten woman who present with a new lump will have cancer.1 Diagnostic Considerations6 Benign: • Fibroadenoma: most common breast mass; a smooth, round, rubbery mobile mass, which is often found in young women; identifiable on US and mammogram • Breast cyst: mobile, often tender masses, which can fluctuate with the menstrual cycle; most common in premenopausal women; presence in a postmenopausal woman should raise suspicion for malignancy; ultrasound is the best method for differentiating between a cystic vs solid structure; a complex cyst is one with septations or solid components, and requires biopsy • Less common causes: Fat necrosis, intraductal papilloma, phyllodes tumor, breast abscess Premalignant: • Atypical Ductal Hyperplasia, Atypical Lobular Hyperplasia: Premalignant breast lesions with 4-6 times relative risk of developing subsequent breast cancer;8 often found incidentally on biopsy and require full excision • Carcinoma in Situ: o Ductal Carcinoma in Situ (DCIS): ~85% of in-situ breast cancers; defined as cancer confined to the duct that

They are distinctly uncommon, however, in the male breast. We report a case of simple benign cyst of the breast in a 58- year-old man newly diagnosed with mantel cell lymphoma. The cyst was first identified incidentally on a staging contrast-enhanced chest computed www.RadiologyCases.com tomography. Further evaluation with mammography and ultrasound revealed a mass that would be typically characterized as a benign simple cyst, but was biopsied since cysts are not known to occur in male breasts. Pathology results from ultrasound-guided core needle biopsy revealed benign cyst and focal fibrosis which was concordant with the imaging findings. In this case report, we will briefly discuss breast cysts in men and their imaging features including mammography and ultrasound.

  • Breast Cyst Aspiration (Ultrasound Guided)
    St. Luke’s Breast & Bone Health 319/369-7216 Breast Cyst Aspiration (Ultrasound Guided) What is a breast cyst? A breast cyst is a fluid-filled sac (like a tiny balloon). Typically breast cysts occur in women between the ages of 35 and 50, but are most commonly found in those approaching menopause. If you are past menopause and taking hormone therapy, breast cysts may still develop. Breast cyst size may vary and change depending on where you are in your menstrual cycle. Most breast cysts occur in the upper half of your breast. They often enlarge and become tender or painful just before your period. They may seem to appear overnight. Breast cysts move easily to the touch. They may feel either soft or hard. When they are close to the skin’s surface, they may feel like a blister, smooth on the outside, but fluid-filled on the inside. However, if the cyst is found more deeply in the breast, it may feel hard as there is more tissue surrounding it. Women may have cysts in their breasts and not even be aware of them. Cysts are known to come back; in fact some women may get cysts several times during their life. Cysts are not cancer and do not change into cancer. However, there are rare instances where a cancer is growing within them or close to them. Simple cysts do not typically require treatment. For some women, breast cysts can be quite painful and they decide to have them drained. What is a cyst aspiration and why is it done? The process of aspirating (draining) breast cysts is a simple one.

Kennedy Boulevard Suite 860 Philadelphia, PA 19103-1847 1-877-825-9106 [email protected] www.surgicalcore.org The SCORE® Curriculum Outline for General Surgery is a list of topics to be covered in a five- year general surgery residency program. The out- line is updated annually to remain contemporary and reflect feedback from SCORE member orga- nizations and specialty surgical societies. Topics are currently listed for four of the six competencies of the Accreditation Council for Graduate Medical Education (ACGME): patient care; medical knowledge; interpersonal and communication skills; and systems-based practice. The patient care topics cover 28 organ system-based categories, with each category separated into Diseases/Conditions and Operations/Procedures. As of this edition, topics within these two areas are then designated as Core (formerly Broad or Essential) or Advanced (formerly Focused or Complex). Additional changes from the previous edition are indicated in the Excel version of this outline, available at www.surgicalcore.org. Please note topics listed in this booklet may not directly match those currently on the SCORE Portal — this booklet is forward-looking, reflecting the latest updates. The Surgical Council on Resident Education (SCORE) is a nonprofit consortium formed in 2006 by the principal organizations involved in U.S. surgical education. SCORE’s mission is to improve the education of general surgery residents through the development of a national curriculum for general surgery residency training.
