Introduction: Ewing’s sarcoma typically involves the bony structures in adolescents and young adults. Extra skeletal sarcoma is a rare, aggressive, malignant soft tissue tumor with high recurrence rate. Ewing’s sarcoma breast is a rare entity with less than 1% cases reported in literature. Case Report: A fifty-five-year-old lady was referred to our institute with history of gradual onset painless breast lump for 1 year. Diagnostic ultrasound of bilateral breast identified a cystic lesion measuring 1.8 cm × 1.5 cm in lower inner quadrant of right breast. She underwent diagnostic excisional biopsy outside which showed malignant small round cell tumor. Post-excisional biopsy whole body 18-fluoro-deoxy-glucose Positron Emission Tomography showed no residual uptake with no evidence of metastatic disease elsewhere. Patient underwent a wide local excision of right breast and followed by adjuvant chemotherapy of 18 weekly VAC regimen. Conclusion: Rarity of Primary breast Ewing’s sarcoma poses a diagnostic dilemma and hence the treatment. The cornerstone of the treatment is local control with systemic therapy. Breast conservation surgery can be equivalent to mastectomy in local control in a good/average breast volume.
