ABSTRACT
INTRODUCTION: Bilateral Breast Carcinoma (BBC) is a rare entity with incidence of synchronous carcinoma being 2-5% of all breast malignancies, which is much less than metachronous carcinoma. Synchronicity/ metachronicity are usually associated with local and lymphatic spread and with blood-borne spread to lungs, bones and liver. Moreover BBC are mostly lobular carcinomas but we report a rare case of Infiltrating Ductal Carcinoma (IDC) as the primary carcinoma and Lobular Carcinoma as the secondary. CASE DESCRIPTION: 56 year old female who presented with a Stage IIIB fungating growth around 10x8cm in the lower inner, lower outer and upper outer quadrant of right breast since 6 months and a StageIIA 4x4cm tumour felt in the left breast in the upper inner and lower outer quadrant. Wedge biopsy of the right breast fungating mass showed Ductal Carcinoma and FNAC of the left breast lump suggested Lobular carcinoma which was confirmed on Histopathology after surgery. Patient was subjected to Hormonal therapy (Tab Tamoxifen), chemotherapy (Cyclophosphamide, 5 FU, and Doxorubicin) followed by Radiotherapy. Patient recovered well and shows no recurrence or signs of metastasis in the 8 months of follow up. DISCUSSION AND EVALUATION: Different histological subtypes with different grades of tumour in both breasts suggested two different synchronous primary tumours. Early detection of the contralateral tumour is of utmost importance emphasising the significance of breast self-examination. Screening tools like MRI have a greater sensitivity compared to Mammography. There are no clear treatment guidelines for bilateral breast cancer. Patients are often treated with bilateral mastectomy, with breast conservative surgery having unclear importance. CONCLUSION: Meticulous diagnosis and appropriate management help to improve the longitivity with an improved quality of life.
