Metaplastic carcinoma is a rare but heterogeneous group of neoplasm of breast, accounting for about 1% of all breast carcinomas. Metaplastic carcinomas may be either low-grade tumors (e.g., adenosquamous carcinoma or spindle cell carcinoma), or high-grade tumors (e.g., squamous cell carcinoma, or spindle cell carcinoma). We report a case of metaplastic breast carcinoma in a 72-year-old lady. The clinical, radiological and histological characteristics are discussed.
