ABSTRACT
Metaplastic breast carcinoma is a very rare disease with many different histologic subtypes including squamous cell, spindle cell, and heterologous mesenchymal growth (sarcomatoid, osseous). We report a case of sarcomatoid metaplastic carcinoma of the breast which was manifested as a well-circumscribed, round, hypoechoic mass on ultrasound.
