INTRODUCTION Cancer of the breast is the most common cancer among females. The current study aims to report and discuss a rare case of breast cancer in the intermammary region. CASE REPORT A 61-year-old lady presented with intermammary swelling for three months. Ultrasound examination showed a hypoechoic micro lobulated mass with internal vascularity seated on the chest wall. There was pathological lymphnodes in the right axilla. Core needle biopsy suspected invasive ductal carcinoma of no specific type. The patient was referred to an oncology center receiving 21 cycles of radiotherapy and hormonal therapy. DISCUSSION The most common site of the occurrence of breast cancer is the upper outer quadrant (found in one-third of patients), followed by the upper inner quadrant (9.4%)-both lower outer and inner quadrants (5.2%) and rarely in the central portion. Intermammary breast cancer is an infrequent finding. CONCLUSION Although it is extremely rare, breast cancer could occur in the intermammary region. It has the same management strategy as breast cancer.
