    A Case of Invasive Ductal Carcinoma with Axillary Skip Metastasis Confined to the Interpectoral (Rotter's) Lymph Node. (PubMed, Surg Case Rep)
    This extraordinarily rare case of axillary skip metastasis limited to the interpectoral node emphasizes the potential for false-negative SN biopsies. Careful review of preoperative images, particularly MRI images, is crucial to avoid understaging. Awareness of interpectoral node involvement may help guide appropriate treatment strategies for selected patients.
