Dual Pathology Breast Carcinoma: A Report of Two Cases Dual pathology breast carcinoma, whether unifocal, multifocal or multicentric may significantly impact patient prognosis. Certain histological combinations are associated with favourable outcomes, while others may indicate a more aggressive disease. We presented a report of two women with different pathological combinations. The first case had multicentric cancers of the left breast. She underwent neoadjuvant chemotherapy, then nipple-sparing mastectomy with axillary dissection and immediate transverse rectus abdominis myocutaneous (TRAM) breast reconstruction. Histopathological assessment revealed a combination of metaplastic carcinoma and invasive micropapillary carcinoma; both aggressive subtypes. Post adjuvant radiotherapy, she remained disease-free for five years. The second case had a unifocal right breast cancer managed with breast-conserving surgery and sentinel lymph node biopsy. Histopathology revealed a combination of invasive carcinoma of no special type (NST) and invasive papillary carcinoma. These subtypes are associated with a more favourable prognosis. Post radiotherapy and on endocrine therapy, this patient remains well at 2 years follow-up. These cases demonstrate the prognostic variability in dual histopathology breast cancers and highlights the importance of individualised treatment. Both patients remain disease free despite having dual pathology breast carcinoma which seem to suggest a more aggressive disease behaviour.
