We experienced a case of left adrenal ganglioneuroma after operation for breast cancer. A 51-year-old woman, who had undergone a modified radical mastectomy for left breast cancer, was admitted to the hospital because of an adrenal tumor. The tumor was found incidentally on ultrasonography during a routine examination. The mass was located between the spleen and left kidney. No abnormal findings were revealed on laboratory and endocrinological studies. Under a preoperative diagnosis of nonfunctioning adrenal tumor, the tumor was removed. The resected material was 320g in weight and 10×10×5cm in size, with capsule.
It communicated with the adrenal gland. The section had homogenous inner part and was solid and grayish white in color. Histological diagnosis was adrenal ganglioneuroma.
Ganglioneuroma originating from the adrenal gland is relatively rare. The patient has been free from recurrence as of 2 years and 10 months after the operation. Adrenal tumor in this case was thought a candidate for operation because it was incidentally found by a routine medical examination after breast cancer and had a large diameter, and a possibility of metastatic tumor could not be ruled out. A review of clinical cases of ganglioneuroma is also presented.
