Palpable soft tissue mass in the right lower axillary region, increased in size in the last 6 months. This is a known mass for the past 6 years. Patient will undergo egg retrieval process seen. A targeted right lower axillary ultrasound was performed for the patient’s area of concern. A 2 cm oval nontender soft mass is palpated in the right lower axillary region along the anterior clavicular line, best in the sitting position. Ultrasound demonstrates an oval parallel rounded hypoechoic mixed echogenic mass measuring 4.6 x 1.3 x 1.7 cm with peripheral blood flow. The mass appears encapsulated with an adjacent small 6 x 4 mm normal morphology lymph node in the vicinity. The mass could arise within the muscle fibers and the skin. No definite glandular tissue is identified in the vicinity.
Palpable abnormality in the right lower axillary region although has benign characteristics with an adjacent normal morphology lymph node, could represent an atypical lipoma or fibroadenolipoma if this appears to be an extension of the breast tissue. Further evaluation with an FNA/core biopsy or MRI is recommended. The findings were discussed with the patient in detail.BIRADS: 3 - Probably benign finding.RECOMMENDATION: H - Percutaneous Biopsy/Aspiration.
