PURPOSE: Laparoscopic adrenalectomy (LA) has become the standard treatment for benign adrenal neoplasm because of the procedure's minimal invasiveness and the patients' earlier recovery. The aim of this study was to evaluate the safety and effectiveness of laparoscopic adrenalectomy for treating pheochromocytoma. METHODS: 19 Operations were performed between March 1993 and July 2004 at Kyung-Hee medical center for treating pheochromocytoma, and the diagnosis was confirmed by the postoperative pathology. There were 5 cases treated with LA and 14 cases treated with open adrenalectomy (OA). The various clinical parameters (tumor location, tumor size, first oral feeding, hospital stay, hemodynamic change and operation time) were compared between the LA and OA procedures, retrospectively. RESULTS: The location of the tumor was 2 : 2 : 1 (left : right : extra-adrenal) in the LA group and 9 : 3 : 2 (left : right : both) in the OA group. The mean tumor size (cm) was 5.4 in the LA group and 6.3 in the OA group. The mean operation time (minutes) was 219 in the LA group and 202 in the OA group. The resumption of liquid diet (days) was 2.2 in the LA group and 3.0 in the OA group (P=0.037). The postoperative hospital stay (days) was 6.3 in the LA group and 8.5 in the OA group. The mean number of intraoperative hypertensive crisis was 1.42 in the LA group and 1.40 in the OA group. The number of cases requiring intraoperative transfusion was 2 of 5 in the LA group and 2 of 15 in the OA group. The use of antihypertensives (number of times) was 1.42 in the LA group and 1.40 in the OA group. The mean highest BP (mmHg) was 162 in the LA group and 165 in the OA group. CONCLUSION: Laparoscopic adrenalectomy for treating pheochromocytoma is a safe and effective procedure that provides the benefits of a minimally invasive approach.

PURPOSE: We report herein 119 patients with pheochromocytoma at our institute over the last 23 years. MATERIALS AND METHODS: Between 1986 and 2009, 119 patients were diagnosed with pheochromocytoma at our institute. We reviewed the medical records of these patients. RESULTS: Of 119 patients, 45 were male and 74 were female, and mean age was 43.83 +/- 13.49 years. Forty-three patients (36.1%) were diagnosed incidentally, and 8 patients (6.7%) were found to have familial pheochromocytoma. The mean dimension of the tumors was 5.89 +/- 3.18 cm. 4 patients had bilateral tumors; three of these patients were found to have familial pheochromocytoma and 1 patient was diagnosed with malignant pheochromocytoma. A total of eight patients (6.7%) were found to have malignant pheochromocytoma. In 1 patient, metastasis to a lymph node was found at the time of diagnosis. Metastases were found at a mean of 49 +/- 25.83 (6-75) months after surgery in the other seven patients. 6 patients died of malignant pheochromocytoma at a mean of 31 +/- 28.71 months (1-81) after diagnosis, and the other 2 patients survived for 15 and 24 months, respectively. CONCLUSION: Approximately 35% of patients with pheochromocytoma are diagnosed incidentally, and the number of detected cases is increasing. Although familial pheochromocytoma was found only in 6.7% of the patients, genetic testing should be considered in all patients, especially in patients with a family history, young age, or multifocal, bilateral, extra-adrenal, or malignant tumors. Given that malignant pheochromocytomas are frequently diagnosed during the follow-up period, long-term follow-up is necessary to confirm the absence of recurrence or metastasis.

We report a case of a 74-year-old female with myxoid adrenocortical adenoma which showed different magnetic resonance imaging findings compared to those of a typical adrenocortical adenoma. The myxoid change in the adrenocortical adenoma is a rare form of degeneration. It presents a considerable diagnostic challenge to both radiologists and clinicians because it can mimic other adrenal tumor types on imaging. The MRI findings of the presented case included a high signal intensity on T2-weighted images similar to that of fluid and delayed progressive enhancement.

We present here a very rare case of metastatic relapse in the pancreas of a 4-year-old boy who had been treated for stage 4 neuroblastoma. Computed tomography showed multiple metastatic masses in the pancreas with secondary pancreatitis. To the best of our knowledge, this is the first case report of pancreatic metastasis in a child with neuroblastoma.

A 29-yr-old man, presented with abdominal pain and fever, had an initial computed tomography (CT) scan revealing low attenuation of both adrenal glands. The initial concern was for tuberculous adrenalitis or autoimmune adrenalitis combined with adrenal hemorrhage. The patient started empirical anti-tuberculous medication, but there was no improvement. Enlargement of cervical lymph nodes were developed after that and excisional biopsy of cervical lymph nodes was performed. Pathological finding of excised lymph nodes was compatible to NK/T-cell lymphoma. The patient died due to the progression of the disease even after undergoing therapeutic trials including chemotherapy. Lymphoma mainly involving adrenal gland in the early stage of the disease is rare and the vast majority of cases that have been reported were of B-cell origin. From this case it is suggested that extra-nodal NK/T-cell lymphoma should be considered as a cause of bilateral adrenal masses although it is rare.

We present two cases of adrenocortical oncocytomas that were well-delineated on multi-detector computed tomography and magnetic resonance imaging. The images showed a well-enhanced large mass with multiple stippled calcifications in a 10-yr-old girl who was consulted due to precocious puberty. A well-enhanced solid mass with necrotic components was incidentally noticed in a 54-yr-old man. These lesions were resected and diagnosed as adrenocortical oncocytomas through immunohistochemical studies and electron microscopy. Adrenocortical oncocytomas are rare disease entities, therefore, we report these interesting, rare adrenocortical oncocytomas here with radiologic findings, and discuss differential diagnosis.

In patients with primary aldosteronism who have bilateral adrenal incidentalomas, it is important to identify which adrenal gland is secreting excess aldosterone. Traditionally, adrenal vein sampling (AVS) has been performed for lateralization despite its invasiveness. Here we report a case of bilateral adrenal incidentaloma in which 18-Fluorodeoxyglucose (FDG)-positron emission tomography (PET) was used to identify the functional adrenal mass. A 53-yr-old man was referred to our clinic due to bilateral adrenal incidentalomas (right: 1 cm, left: 2.5 cm) on computed tomography (CT). Given his history of colon cancer, FDG-PET/CT scanning was used to rule out metastasis. Although there was focal hot uptake lesion in the right adrenal gland, the patient was suspected primary aldosteronism clinically more than metastasis because of the patient's underlying hypertension with hypokalemia. It was consistent with the results of AVS. Based on these findings, we propose that FDG-PET/CT can be used instead of AVS to identify the source of primary aldosteronism between two bilateral adrenal incidentalomas.
