Zorluk: OrtaBreast Disorders

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. She completed the antibiotics, but her symptoms have continued to worsen. On physical examination, her vital signs are within normal limits. The left breast is visibly enlarged and erythematous compared to the right. The skin of the left breast exhibits diffuse thickening and prominent pores, resembling the skin of an orange. The left nipple is newly retracted. Palpation of the left axilla reveals a firm, fixed, 2.5-cm lymph node. Which of the following is the most appropriate next step in the evaluation of this patient?

  1. Diagnostic mammography and targeted ultrasound of the breastCevap
  2. B
    Admission to the hospital for intravenous vancomycin and cefepime
  3. C
    Incision and drainage of the affected breast tissue
  4. D
    Reassurance and routine screening mammography in 1 year
  5. E
    Application of a high-potency topical corticosteroid

Cevap

Diagnostic mammography and targeted ultrasound of the breast
This patient's presentation of a rapidly progressive, erythematous, swollen breast with skin thickening (peau d'orange), nipple retraction, and axillary lymphadenopathy that failed to improve with antibiotics is highly suspicious for inflammatory breast cancer (IBC). IBC is an aggressive form of primary breast carcinoma characterized by dermal lymphatic invasion by tumor cells, which obstructs lymphatic drainage and causes the classic peau d'orange appearance. The most appropriate next step in evaluation is bilateral diagnostic mammography and targeted ultrasound of the breast and regional lymph nodes. This imaging assesses the extent of the underlying mass and nodal involvement. Following imaging, a core needle biopsy of the breast tissue and a skin punch biopsy must be performed to histologically confirm the diagnosis.

Adım Adım Çözüm

1
Identify the key clinical features and the patient's lack of response to prior treatment.
The patient has unilateral breast erythema, edema, peau d'orange (thickened skin with prominent pores), nipple retraction, and axillary lymphadenopathy that did not improve with appropriate antibiotic therapy for mastitis.
Recognizing red flag signs of inflammatory breast cancer is crucial for distinguishing it from benign inflammatory conditions.
2
Determine the most appropriate next step in the diagnostic evaluation for suspected inflammatory breast cancer.
Diagnostic mammography and targeted ultrasound of the breast and regional lymph nodes are indicated.
Imaging is required to evaluate the extent of the parenchymal disease and regional nodal involvement prior to performing a tissue biopsy for definitive diagnosis.
