Abstract

<p>The patient is a 65-year-old woman diagnosed with right breast cancer, cT4bN1M0 Stage IIIB (invasive ductal carcinoma, ER 50%, PgR 20%, HER2 3+). Contrast-enhanced magnetic resonance imaging of the breast showed hypoplasia of the right pectoralis major and absence of the right pectoralis minor. Hypoplasia of the right fingers led to the diagnosis of Poland's syndrome. The patient received preoperative chemotherapy with endocrine therapy and underwent right mastectomy and axillary node dissection. Postoperatively, the patient received endocrine therapy, molecular-targeted drug therapy, and radiotherapy. Three years and eight months after the operation, the patient is alive without cancer recurrence. We should pay attention to the operation of the breast cancer in patients with Poland syndrome because the unique anatomy of this condition can easily lead to misidentification of blood vessels and nerves.</p>
