Metastases to the adrenal glands are frequently found at autopsy. In practice, adrenal metastases have generally been accepted as evidence of blood-borne systemic disease. So, clinically curable adrenal metastases is a rare malady. The role for surgical resection in adrenal metastases has not been clearly defined. A 45-year-old man initially underwent total gastrectomy with D2 lymph node dissection for treating his advanced gastric cancer. A solitary adrenal metastases was resected 1 year later. The patient has survived for 3 years and no further evidence of disease was found on his last follow-up examination. We report here on this case to show that for selected cases, surgical resection of adrenal metastases is feasible and this procedure may extend survival for metastatic gastric cancer patients.

Cushing's syndrome is very rare in infancy, especially in Korea. We observed a case of Cushing's syndrome in a one year and 2 month old female baby with the complaints of a 3 months history of obesty and hirsutism and 2 months history of polyphagia. There were retarded bone age, hypertension, increased urinary excretion of 17-hydroxycorticosteroid and 17-ketosteroid and eosinopenia but no thymic shadow in the chest X-ray. There was no response to the dexamethasone test (2mg divided in 4 doses orally for 2 days), which suggested an adrenal tumor. Intravenous pyelography showed that the left kidney was displaced downward as compared to the right kidney and there was a henegg sized radio-opaque shadow at the upper pole of the left kidney suggesting a left adrenal tumor. The tumor, reported as a benign adenoma pathologically, was removed successfully by anterior abdominal approach. Hypertension, eosinopenia and hypokalemia were raturned to normal from 3 days after surgery but 17-hydroxycorticosteroid and 17-ketosteroid were returned to normal from 2 weeks after surgery. We have presented this case and have reviewed the literature.

OBJECTIVETo study and summarize the diagnosis and treatment for the corticomedullary mixed tumor of adrenal gland.

METHODSThe 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.

RESULTSAdrenalectomy was performed in the 25 cases, which contain 9 cases of open operations and 16 cases of endoscopic adrenalectomies. 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.

CONCLUSIONSIn 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.

To discuss the pathology, clinical manifestation, diagnosis, therapy and prognosis of mature teratoma in adrenal gland. We reported 2 cases of mature adrenal teratoma and summarized their characters. No local recurrence or metastasis was found in the close follow-up of the 2 patients after the radical resection. Teratomas are rare germ tumors with potential malignant character which usually occur in the testes and ovaries. Adrenal teratomas are extremely rare and the diagnosis relies on radiological examinations. Early diagnosis and early surgical resection are the key in the treatment. Whether the postoperative chemotherapy is needed depends on the pathological result. Close lifelong follow-up is recommended and the prognosis is unclear at present.

A 57-year-old male patient was referred to our department with complaints of his right adrenal gland occupancy and hypertension about 6 months. When admitted to the hospital, the blood pressure was about 160/100 mmHg, and the heart rate was 110 beats/min. He was no obvious obesity, acne, abnormal mood, without weakness of limbs, acral numbness, palpitation and headache. He presented with type 2 diabetes for more than 3 years, with oral administration of metformin enteric coated tablets and subcutaneous injection of insulin glargine to control blood glucose, and satisfied with blood glucose control. Enhanced CT showed that: the right adrenal gland showed a kind of oval isodense, slightly hypodense shadow, the edge was clear, lobular change, the size was about 5.8 cm×5.4 cm, uneven density, there were nodular and strip calcification, round lipid containing area and strip low density area, and the CT value of solid part was about 34 HU. Enhanced scan showed heterogeneous nodular enhancement in the solid part of the right adrenal gland, nodular enhancement could be seen inside. The CT values of solid part in arterial phase, venous phase and delayed phase were 45 HU, 50 HU and 81 HU, respectively. Considering from the right adrenal gland, cortical cancer was more likely. No obvious abnormality was found in his endocrine examination. After adequate preoperative preparation, retroperitoneal laparoscopic adrenalectomy was performed under general anesthesia. During the operation, the 6 cm adrenal tumor was closely related to the inferior vena cava and liver, and after careful separation, the tumor was completely removed and normal adrenal tissue was preserved. The operation lasted 180 min and the blood loss was 100 mL, and the blood pressure was stable during and after the operation. There was no obvious complication. The results of pathological examinations were as follows: the size of the tumor was 7.5 cm×6.0 cm×3.5 cm, soft, with intact capsule and grayish-red cystic in section. Pathological diagnosis: (right adrenal gland) cavernous hemangioma, secondary intravascular thrombosis, old hemorrhagic infarction with calcification and ossification. After 6 months of observation, no obvious complications and tumor recurrence were found. In summary, cavernous hemangioma of adrenal gland is a rare histopathological change. Its essence is a malformed vascular mass. Blood retention is the cause of thrombosis and calcification in malformed vessels. The imaging findings were inhomogeneous enhancement of soft tissue masses, and the adrenal function examination showed no obvious abnormalities. Retroperitoneal laparoscopic surgery is feasible after adequate preoperative preparation. It is difficult to diagnose the disease preoperatively and needs to be confirmed by postoperative pathology.

We report one case of estimated glomerular filtration rate (eGFR) decline after taking unilateral adrenalectomy due to aldosterone adenoma. A 60-year-old male with 23-year history of hypertension was reported to the endocrinologist due to hypokalemia (serum potassium 3.01 mmol/L). Urine microalbumin/creatinine (ALB/CR) was 70.15 mg/g, serum creatinine was 82 μmol/L and eGFR was 89.79 mL/(min·1.73 m²). Random serum aldosterone was 172.2-203.5 ng/L, and random plasma rennin activity was 0-0.17 μg/(L·h). His captopril challenge test suggested that his aldosterone le-vels were suppressed by 8% (< 30%) and the adrenal enhanced computed tomography scan revealed a left adrenal tumor. The patient was diagnosed with primary hyperaldosteronism (PA), aldosterone adenoma and underwent left laparoscopic adrenalectomy. Histological examination confirmed adrenal cortical adenoma. One week after the operation, his serum creatinine was increased to 127 μmol/L compared with preoperative level; eGFR was 32.34 mL/(min·1.73 m²). His systolic blood pressure (SBP) was 110 mmHg and diastolic blood pressure (DBP) was 60 mmHg (hypotensive drugs discontinued), and serum potassium level was 5.22 mmol/L. At the end of the 2-year follow up, the serum creatinine of this patient remained at 109-158 μmol/L and eGFR fluctuated from 63.28-40.12 mL/(min·1.73 m²). PA is one of the most common causes of secondary hypertension. Several studies have reported renal function deterioration of PA patients after unilateral adrenalectomy, like the patient in this article. Age, preoperative plasma aldosterone concentration, albuminuria and preoperative potassium level might be significant predictors of a decrease in the eGFR. Growing evidence suggests that aldosterone could contribute to structural kidney damage, arterial injury and hemodynamic disorder. At the same time, patients with PA exhibit glomerular hyperfiltration and glomerular vascular hypertension, leading to the misinterpretation of renal function in PA patients as subtle kidney damage may be masked by the glomerular hyperfiltration before treatment. After a unilateral adrenalectomy, glomerular hyperfiltration by aldosterone excess is resolved and renal damage can be unmasked. In conclusion, kidney function deterioration after adrenalectomy can be detected in some patients with PA. Thus, accurate evaluation of kidney function in patients with PA may be essential, especially for those with preoperative risk factors for postoperative renal impairment. After unilateral adrenalectomy, close monitoring of renal function and adequate management are required for PA patients.

BACKGROUNDWith a trend that renal tumors are being detected at an earlier stage, classical radical nephrectomy is being reconsidered. More conservative techniques are being proposed. To clarify the indication for synchronous adrenalectomy in radical nephrectomy for renal cell carcinoma which has been questioned since the 1980s, this study evaluates the role of adrenalectomy and recommends a new indication for adrenalectomy in renal cell carcinoma.

METHODSA systemic search was performed, using PubMed and Google Scholar, of all English language studies published up to March 2012 that compared adrenalectomy with adrenal-sparing surgery, in surgery for renal cell carcinoma. We assessed preoperative imaging for adrenal involvement and the relationship of tumor location with adrenal metastases. Twenty-one studies (20 retrospective and 1 prospective) involving 11 736 patients were included.

RESULTSThe mean incidence of ipsilateral adrenal involvement from renal cell carcinoma was 4.5%. Synchronous adrenalectomy did not alter survival (hazard ratio (HR) = 0.89, 95% confidence interval (CI) 0.67 - 1.19, P = 0.43; odds ratio (OR) = 1.10, 95%CI 0.84 - 1.44, P = 0.49). Upper pole tumors were not associated with a higher incidence of ipsilateral adrenal metastases. Pooled preoperative imaging: sensitivity, specificity, positive predictive value and negative predictive value were 92% (95%CI 0.84 - 0.97), 95% (95%CI 0.93 - 0.96), 71.6% and 98.5% respectively.

CONCLUSIONSAdrenal involvement from renal cell carcinoma is rare, even in advanced tumours. Synchronous adrenalectomy does not offer any benefit, even for "high risk" patients. We suggest that only patients with a positive preoperative adrenal finding on preoperative imaging for a solitary adrenal metastasis should undergo adrenalectomy as part of the radical nephrectomy.

OBJECTIVETo evaluate the safety and efficacy of retroperitoneal laparoscopic resection for pheochromocytoma.

METHODSThe clinical data of 107 cases of pheochromocytoma in PUMCH from 2003 to 2008 were analyzed retrospectively. There were 58 males and 49 females with an age range from 8 to 77 years (mean 44 years) in this cohort. One hundred and two cases were intra-adrenal and 5 extra-adrenal. Of the 102 intra-adrenal tumors, 43 tumors were located in left adrenal, 51 in right adrenal and 8 in both sides. All of the 5 extra-adrenal tumors were at para-abdominal aorta. Retroperitoneal laparoscopic resection was performed for the 107 cases. This period was separated to 3 stages based on the degrees of the practical ability for retroperitoneal laparoscopic resection, such as tentative and exploratory stage, accumulative stage, and mature stage.

RESULTSAt tentative and exploratory stage from June 2003 to December 2003, 10 cases underwent retroperitoneal laparoscopic surgery, of which 3 cases were converted to open surgery. The mean diameter was 4.2 cm (range in diameter from 2.5 cm to 6.0 cm). The mean operation time was 105 min (range from 60 min to 230 min). The mean volume of blood loss during operation was 620 ml (range from 150 ml to 1800 ml). At accumulative stage from January 2004 to December 2006, 66 cases underwent retroperitoneal laparoscopic surgery with none converted to open surgery. The mean diameter was 5.7 cm (range in diameter from 2.1 cm to 8.7 cm), and the diameter was above 6.0 cm in 19 cases. The mean operation time was 95 min (range from 40 min to 210 min). The mean volume of blood loss during operation was 350 ml (range from 50 ml to 1800 ml). At mature stage from January 2007 to June 2008, 31 cases, including 5 extra-adrenal pheochromocytomas, underwent retroperitoneal laparoscopic surgery. The mean diameter was 6.5 (range in diameter from 1.5 cm to 12.3 cm). The mean operation time was 75 min (range from 40 min to 160 min). The mean volume of blood loss during operation was 180 ml (range from 50 ml to 800 ml). No peri-operative death occurred. Follow up period was ranging from 1 to 62 months (the mean was 34 months), and 7 failed to be followed up, 3 cases recurred. And there was no distant metastases and death case.

CONCLUSIONSRetroperitoneal laparoscopic surgery for pheochromocytoma is feasible and safe. This procedure will be more and more performed as the advancement of the skill and accumulation of experience. The dimension, recurrence and location of tumor are not the absolute contraindication of retroperitoneal laparoscopic surgery for pheochromocytoma.
