Purpose: The purpose of this study was to describe the biological behaviour of mucinous breast carcinoma (MBC) regarding their clinical presentations, pathological features, prognosis and survival. Methodology: We conducted this retrospective study from 2006 to 2015 (10-year duration) and included all the patients who presented with mucinous carcinoma of the breast at any age. We excluded all the patients who presented with invasive ductal carcinoma or other rare breast tumours. Each patient with mucinous carcinoma breast was categorised in terms of diagnosis, surgery, chemotherapy and outcome. For categorical variables, Chi-square test was used. Kaplan–Meier curves were used to determine estimated overall survival. Data analysis was carried out using the SPSS 20. Results: In total, 8841 patients with breast carcinoma presented during the study period. Of these, 74 patients were diagnosed as cases of MBC, constituting 95%. Conclusion: Mucinous carcinoma is a rare breast carcinoma with a good prognosis. Key words: Breast cancer, mucinous carcinoma, prognosis
