Case Discussion

Due to the history of lactation, breast abscess was suspected clinically; however, breast ultrasound examination showed an extramammary lesion inferolateral to the right breast/axilla, within the muscles of the chest wall. Its exact nature could not be determined confidently and further evaluation with MRI was recommended, which, however, could not be done due to the claustrophobia. Ultrasound-guided fine needle aspiration (FNA) was done which was non-diagnostic and later on the patient was referred to the surgeon for complete excision.
