Extraosseous sarcoma of the breast occurs infrequently and is a harbinger of poor prognosis. The histogenesis of this tumor is ambiguous, and it can arise both in de novo and metastatic settings. Morphologically, it is indistinguishable from its skeletal counterpart, and clinically, it presents similarly to any other subtype of breast cancer. Tumor recurrence with a propensity for hematogenous rather than lymphatic spread plagues this malicious disease. The treatment guidelines are mainly derived from the those of other extraskeletal sarcomas as the literature is limited in this context. We hereby present 2 clinical cases with similar clinical profiles and different treatment outcomes. The intent of this case report is to contribute to the limited database available for the management of this rare disease.
