There is a small well-defined heterogeneous echogenicity lesion measuring 8 x 13 mm in the superficial subcutaneous soft tissues of right upper posterior chest wall. It has a well-defined hypoechoic rim / capsule. Multiple tiny hyperechoic foci, likely calcifications, are seen in it. There is internal vascularity in the lesion on Doppler ultrasound examination. These ultrasound features are overall suggestive of a benign pathology and possible differential diagnosis includes sebaceous cyst, dermoid cyst, or epidermal inclusion cyst.
