OB/GY Flashcards
Clear cell carcinoma of the vagina - large cells with abundant clear cytoplasm RISK FACTOR?
DES - diethylstilbestrol - synthetic estrogen used in the 40s to prevent miscarriage > discontinued in 1970 because of transplacental carcinogen potency for vaginal cancer (daughters of these women) and breast cancer (mothers).
LEEP - loop electrosurgical excision procedure
Remove high-grade intraept lesions of the cervix
Fibroadenoma - solid mass with well-defined borders and low clinical suspicion for malignancy - MANAGEMENT
Reassurance and follow-up examination in 6 months
Risk factors for ENDOMETRIAL CANCER
Nulliparity, obesity, diabetes mellitus, late menopause, tamoxifen use…
Phyllodes tumor - pathology
Leaf-like architecture of papillary projections of epthelium-lined stroma;
Lobular appearance on mammography (can be similar to fibroadenoma)
Phyllodes tumor - clinical presentation
Painless breast lump: Lesion >3cm, rapidly enlarging with NO AXILLARY LYMPHADENOPATHY associated. 25% is malignant - surgery with wide margins is required
Invasive ductal carcinoma - malignant cells in the ducts with micro calcification and stromal invasion - CLINICAL PRESENTATION
Most common form of breast cancer; painless breast mass, often associated with skin changes ( retraction, dimpling, edema), nipple retraction, bloody nipple discharge, and/or lymphadenopathy.
Invasive lobular adenocarcinoma - malignant cells in lobules and monomorphic cells in single rows
10-15% of breast cancers; painless nodule, skin changes, nipple retraction, bloody nipple discharge, lymphadenopathy
Intraductal papilloma - central, branching fibrovascular core with surrounding myoepithelial and epithelial cells.
Multiple/single, sometimes palpable lesions with serous or bloody nipple discharge (60-80%)
Paget disease of breast
Erythematous and scaly rash affecting the nipple and areola, accompanied by pruritus, burning, nipple retraction, blood-tinged nipple discharge (Ductal Carcinoma)
Fibrocystic breast disease - focal lesions of thick parenchyma or cysts
Most common benign condition of the breast - palpable breast mass; mastalgia, cyclic pain with menses and clear/white nipple discharge
Cardiotocogram
Fetal heart rate range: 6-25bpm
Decelerations: diration <60s, abrupt <30s from onset to nadir, vary in shape, temporal relationship with uterine contractions, occur with <50% of uterine contractions over a 20-minute time period =intermittent variable decelartions
Fat necrosis of the breast - oil cysts; foam cells and multinucleated giant cells
Benign; trauma related; exam and radio mimics malignancy - DOES NOT increase the risk of breast cancer > reassurance and follow-up
Solitary malignant tumor treatment
Lumpectomy with axillary staging
Radiation
Anastrozole
Postmenopausal women with HR + breast cancer
Tamoxifen
Premenopausal HR+ breast ca
Trastuzumab
HER2+ breast cancer
Endometriosis definitive diagnosis
LAPAROSCOPY - Presumptive clinical diagnosis but inconclusive imaging findings, no response to medical therapy or to exclude malignancy
Presence of small bluish endometric lesions - POWDER-BURN
Letrozole - aromatase inhibitor
First-line pharmacotherapy for ovulation induction in PCOS
Better than clomiphene
Bromocriptine - dopamine agonist
Anovulatory infertility in hyperprolactinemia
