Experience of Ultrasound-Guided Vacuum-Assisted Excision of a Phyllodes Tumor Arising From Ectopic Axillary Breast Tissue: A Case Report

An axillary breast is a common condition, which can cause various diseases arising from the breast tissue. Among these diseases, phyllodes tumors are very rare fibroepithelial tumors, which resemble fibroadenomas. Surgical removal is the treatment of choice for phyllodes tumors to prevent recurrence. Inpatient treatment and general anesthesia are required for surgical removal, and fibrosis, skin scarring, and neurological symptoms may occur after surgery. Ultrasound-guided vacuum-assisted excision, because of its advantages, is an alternative to surgical excision for clinically benign breast masses. Therefore, in cases of clinically benign or concordant benign lesions, following a core needle biopsy, ultrasound-guided vacuum-assisted excision can be considered with sufficient preoperative measures and close follow-up of the ectopic axillary breast.
