Obstetrics and Gynecology

A 58-year-old nulliparous woman is evaluated in the clinic following a recent breast biopsy. She initially presented with a vague firmness in her left breast. Subsequent mammography revealed a 2.2-cm irregular, highly dense lesion with radiating spicules and clustered pleomorphic microcalcifications in the lower outer quadrant. Ultrasound imaging confirmed a solid, hypoechoic mass with architectural distortion and posterior acoustic shadowing. An uncomplicated core needle biopsy was performed under ultrasound guidance. The pathology report indicates fragments of dense fibrous stroma and benign ductal epithelium, with no atypical cells identified. The patient takes no medications and has no family history of breast cancer. On physical examination, there is a vague thickening in the left lower outer quadrant but no dominant mass. Which of the following is the most appropriate next step in this patient's care?

A 62-year-old postmenopausal woman is diagnosed with a 1.8-cm, estrogen receptor-positive, progesterone receptor-positive, HER2-negative invasive ductal carcinoma of the right breast via core needle biopsy. Clinical examination and preoperative imaging reveal no evidence of axillary lymphadenopathy or distant metastases. The patient elects to undergo breast-conserving therapy. Arrange the following management and therapeutic steps in the most appropriate chronological order for this patient's definitive care.

A 36-year-old woman comes to the clinic due to nipple discharge for the past month. She first noticed small, dark red stains on her bra. Over the past week, she has been able to express fluid from her right nipple by gently squeezing it. The fluid is frankly bloody. She has no breast pain, skin changes, or noticeable lumps. The patient's menstrual cycles are regular, occurring every 28 days, and she is nulligravida. She takes no medications and has no family history of breast or ovarian cancer. Her vital signs are within normal limits. On physical examination, both breasts are symmetric with normal skin architecture. There are no palpable breast masses or axillary lymphadenopathy. Gentle compression of the right areola elicits a few drops of bloody fluid from a single duct on the right nipple. The left breast examination is unremarkable. Which of the following is the most likely underlying pathological finding in this patient?

Match each patient's clinical presentation with the most likely histopathological finding on breast biopsy.

A 56-year-old menopausal patient is evaluated in the clinic after noticing a hard, painless nodule in her left breast.

Arrange the following steps in the most appropriate chronological sequence for the complete evaluation and standard management of this patient's condition.

Following an uncomplicated total abdominal hysterectomy for symptomatic leiomyomas, a $42$-year-old female presents to the acute care clinic on postoperative day $6$ for evaluation of new-onset abdominal pain. For the past $48$ hours, she has experienced steadily worsening left lower quadrant pain that radiates to the left groin. The pain makes it difficult for her to lift her left leg when walking. She reports normal flatus, bowel movements, and urination. She has not had chills or vomiting. Vital signs are temperature $37.1^\circ\text{C}$ ($98.8^\circ\text{F}$), blood pressure $118/76\text{ mm Hg}$, pulse $92/\text{min}$, and respirations $14/\text{min}$. The surgical incision is clean, dry, and intact. Abdominal examination reveals a soft abdomen with deep tenderness in the left lower quadrant, lacking rebound tenderness or rigidity. When the examiner places a hand on the patient's left distal thigh and asks her to flex her hip against resistance while supine, the patient winces in severe pain. Laboratory evaluation reveals a leukocyte count of $8,500/\text{mm}^3$ and a hemoglobin concentration of $9.2\text{ g/dL}$ (down from $12.1\text{ g/dL}$ on postoperative day $1$). Which of the following is the most likely explanation for this patient's presentation?

During a routine prenatal visit, a 34-year-old primigravida at 16 weeks gestation reports a newly discovered lump in her left breast. She states she noticed the abnormality approximately three weeks ago while showering. She has no significant past medical history and no family history of breast or ovarian cancer. Vital signs are within normal limits. Physical examination reveals a 2.5-cm, hard, fixed mass in the upper outer quadrant of the left breast. There is no nipple retraction, skin dimpling, or palpable axillary adenopathy. A targeted ultrasound of the breast is performed and demonstrates a 2.6-cm solid, hypoechoic lesion with irregular, spiculated margins and posterior acoustic shadowing. Which of the following is the most appropriate next step in management?

Which of the following is the most appropriate next step in management?

A 55-year-old asymptomatic woman undergoes a routine screening mammogram. The radiology report notes a new, 8-millimeter cluster of pleomorphic microcalcifications in the upper outer quadrant of the left breast. The patient has no personal or family history of breast cancer. On physical examination, the breasts are symmetric with no skin dimpling, nipple retraction, or erythema. Palpation reveals no distinct masses, and there is no axillary lymphadenopathy. Arrange the following steps in the most appropriate chronological sequence for the evaluation and definitive management of this patient's findings, assuming the lesion is confirmed to be an early-stage malignancy.

Nipple discharge can be a presenting symptom for various benign and malignant breast pathologies. Based on the characteristics of the discharge and associated physical exam findings, match each patient's clinical scenario with the most appropriate underlying diagnosis.

A 52-year-old woman presents to the clinic complaining of progressive left breast swelling, redness, and heaviness over the past month. She reports no fever, chills, or breast trauma. She is postmenopausal and has never had breast cancer. Two weeks ago, she visited an urgent care clinic and was prescribed a 10-day course of oral dicloxacillin for presumed mastitis.

A 54-year-old female is evaluated in the emergency department on postoperative day 5 after undergoing an elective total laparoscopic hysterectomy for symptomatic leiomyomas. The operative report notes that the surgery was technically difficult due to dense pelvic adhesions.
