Zorluk: OrtaBreast and Endocrine Surgery

Match each patient's clinical presentation with the most appropriate surgical management or preoperative intervention.

  • A 25-year-old woman with a rapidly growing, 4-cm mobile breast mass; core needle biopsy reveals stromal overgrowth and a leaf-like architectural pattern.Wide local excision with at least 1-cm margins without axillary staging.
  • A 32-year-old woman with episodic diaphoresis, tachycardia, and severe hypertension; biochemical testing and imaging confirm a 4-cm unilateral adrenal mass.Preoperative alpha-adrenergic blockade followed by laparoscopic adrenalectomy.
  • A 55-year-old man with recurrent nephrolithiasis and hypercalcemia; a sestamibi scan demonstrates a solitary focus of persistent uptake in the lower right neck.Targeted parathyroidectomy utilizing intraoperative parathyroid hormone monitoring.
  • A 45-year-old man with a 3-cm thyroid nodule; fine-needle aspiration confirms papillary carcinoma and ultrasound reveals suspicious central compartment lymph nodes.Total thyroidectomy accompanied by central compartment neck dissection.

Cevap

The correct pairings are: the phyllodes tumor requires wide local excision without axillary staging; the pheochromocytoma requires alpha-adrenergic blockade prior to laparoscopic adrenalectomy; the parathyroid adenoma requires targeted parathyroidectomy with intraoperative PTH monitoring; and the papillary thyroid carcinoma with positive nodes requires total thyroidectomy with central compartment neck dissection.
Each clinical scenario corresponds uniquely to a specific surgical principle in breast and endocrine surgery: phyllodes tumors require wide margins without nodal staging; pheochromocytomas require alpha-blockade; localized parathyroid adenomas are treated with targeted excision and PTH monitoring; and node-positive thyroid cancers require total resection and lymphadenectomy.

Adım Adım Çözüm

1
Diagnose the breast mass based on age, rapid growth, and leaf-like biopsy architecture.
Diagnosis is phyllodes tumor.
Phyllodes tumors are fibroepithelial lesions requiring wide margins; they spread hematogenously, making axillary staging unnecessary.
2
Identify the etiology of the episodic diaphoresis and hypertension with an adrenal mass.
Diagnosis is pheochromocytoma.
Surgical manipulation of a pheochromocytoma triggers massive catecholamine release; preoperative alpha-blockade is mandatory to prevent cardiovascular collapse.
3
Evaluate the hypercalcemia, nephrolithiasis, and positive sestamibi scan.
Diagnosis is primary hyperparathyroidism due to a solitary adenoma.
Preoperative localization allows for a targeted, minimally invasive excision rather than a bilateral four-gland exploration, confirmed by intraoperative PTH decay.
4
Determine the surgical extent for papillary thyroid carcinoma with suspicious nodes.
Management is total thyroidectomy with central neck dissection.
While small PTCs without node involvement can sometimes be managed with lobectomy, clinical nodal involvement mandates a complete thyroidectomy and targeted node clearance.
