A Case of Bilateral Inflammatory Breast Cancer

Inflammatory breast cancer (IBC) is an aggressive form of breast carcinoma. Bilateral occurrences of IBC within a short time frame are rare, particularly without significant surgical intervention. This case presents a patient with contralateral recurrence of IBC less than a year after the initial diagnosis. A 39-year-old female was diagnosed with stage IV inflammatory breast cancer in her left breast. Less than a year later, extensive disease was found in her right breast. The patient had received incomplete treatment for the left IBC due to barriers to accessing care. Imaging confirmed the presence of inflammatory breast cancer in the contralateral breast, along with regional adenopathy and metastases. The patient began a chemotherapy regimen similar to her previous treatment. This case highlights the uncommon occurrence of contralateral recurrence of IBC and the hypothesized mechanism of lymphatic spread, suggesting local metastasis rather than a new primary tumor. The patient’s incomplete treatment and lack of surgical intervention likely contributed to the development of contralateral IBC. The case underscores the importance of magnetic resonance imaging (MRI) in evaluating soft tissue and lymphatic changes in IBC. Barriers to care negatively impact prognosis, emphasizing the need for timely follow-up, diagnostic imaging, and oncologic therapy for successful treatment.
