[Diagnosis and treatment for the corticomedullary mixed tumor of adrenal gland].
OBJECTIVE
To study and summarize the diagnosis and treatment for the corticomedullary mixed tumor of adrenal gland.


METHODS
The clinical data of 25 cases of adrenal corticomedullary mixed tumor from January 2000 to April 2008 were analyzed retrospectively, which including 9 males and 16 females. The ages were from 25 to 60 years old, and the average age was 39 years old. Thirteen cases had paroxysmal hypertension and 11 cases had central obesity, as well as 8 cases with hypokalemia. There were different degree abnormalities in plasma endocrine hormones in laboratory examination. Every case underwent b-ultrasound and CT normal plus extensive scan to make the diagnosis.


RESULTS

All of the cases had blood pressure fluctuation during dissection of the adrenal tumors, with the highest blood pressure reached to 230/140 mm Hg (1 mm Hg = 0.133 kPa). Postoperative histopathological study revealed that the pathological changes was corticomedullary mixed tumor of adrenal gland, which was supported by immunohistochemical study.


CONCLUSIONS
In cases with complex phenomenon that can't explain with single cortical or medullary changes, it must beware of the mixed pathological changes in adrenal gland.
