The adrenal gland is a frequent site for metastasis, and the majority of the metastatic lesions of the adrenal gland normally originate from lung cancer, colon cancer, renal cell carcinoma, and melanoma. However, adrenal gland metastasis from breast invasive mucinous carcinoma is extremely rare. This report described a rare case of right adrenal gland metastasis in a 48-year-old female, who was diagnosed with breast invasive mucinous carcinoma and underwent right modified radical mastectomy with axillary lymph node dissection 5 years previously. A mass located on the right adrenal gland was detected during a routine examination 2 months ago. The patient was asymptomatic and adrenal gland MRI revealed a mass in the right adrenal gland. Definitive preoperative diagnosis failed to be established. Right adrenal gland laparoscopic adrenalectomy was performed and the diagnosis of adrenal gland metastasis of breast carcinoma was confirmed by pathological and immunohistochemical examination, especially ER, PR, GATA3, and HER-2. The patient remained in good condition by the time of writing.
