Introduction and Patient Profile: Carcinosarcoma of the breast is a rare malignancy composed of two cell lines described as a ductal-type carcinoma with a sarcoma-like component. It is an aggressive neoplasm that is usually larger in size than epithelial breast cancers and characterized by a rapid increase in size. A 32-year-old woman presented with a palpable lump in the left upper outer breast. Imaging findings and an ultrasound-guided biopsy demonstrated a malignant neoplasm with chondroid differentiation. Interventions and Outcomes: The patient underwent a modified radical left breast mastectomy with sentinel node biopsy. Pathology report from the mastectomy demonstrated an infiltrating metaplastic carcinoma (MPC) with positive lymph nodes. Discussion: The most unusual feature of this case is the lymph node positivity, as lymphatic spread is uncommonly associated with carcinosarcoma or any subtype of metaplastic carcinoma of the breast. This case is important because it illustrates the potential future need for treatment guidelines for this uncommon tumor.
