Abstract

The incidence of synchronous bilateral invasive breast cancer (SBBC) is reported to range from 0.8%-3.0%. Lower disease-free survival and high rates of distant metastasis is a recognized feature of bilateral synchronous tumors, which therefore have a worse overall survival compared to unilateral tumors. Early detection of the contralateral tumor is of utmost importance emphasizing the significance of breast self-examination. Here we report a case of SBBC with invasive ductal carcinoma on both sides in a 50-year-old lady. The pathology report on both sides was infiltrating ductal carcinoma and ductal carcinoma in situ, nuclear grade of ІІ/ІІІ and histologic grade of II/III. Perineural invasion was present on both sides but vascular invasion only on the right side. In conclusion, SBBC is rare, but is important because it may have worse prognosis, different hormone receptor status and treatment modality. Early detection with breast self-examination is highly emphasized.
