We report the case of a 72-year-old man with a right adrenocortical mass who had undergone complete tumour excision with the adrenal gland and around adipose tissue. Pathologic examination led to a final diagnosis of primary sarcomatoid carcinoma of the right adrenal gland. The patient was without recurrence at the one year follow-up. To our knowledge, this is the first case in China and the second reported case in English published studies.
