Though breast carcinoma is one of the most common malignancies worldwide, adequate knowledge of this disease is still very poor. Pure primary squamous cell carcinoma of breast is one such mystery, which is encountered very rarely. Its clinical behavior should not be correlated with the standard infiltrating duct carcinoma of breast. It follows an atypical presentation in terms of tumor size, lymph node and systemic spread. It is generally a triple negative tumor with an aggressive behavior and resistance to standard chemotherapeutic regimens. Management decisions need to be individualized with emphasis toward platinum-based chemotherapy and targeted therapy.
