Abstract
A case of huge breast cancer arising in the left axilla is reported. A 72-year-old female presented with a rapidly enlarging tumor (14×10×5 cm) located in the left axilla accompanying with inflammation of the surrounding skin. Clinically, no tumor was palpable in the left breast and mammography showed no abnormal findings. A variety of examinations searching for other original lesions causing metastasis to the axillary lymph nodes revealed no abnormal finding. After achieving histopathological diagnosis of breast cancer (solid tubular adenocarcinoma) using frozen section, modified radical mastectomy was performed. Histopathologically, no cancer lesion was found in the excised mammary gland and 4/8 lymph nodes were positive for metastasis. The patient had received chemotherapy (5 FU 150 mg/day) for one year and presently she is alive with no evidence of recurrence two years after operation.
