Unilateral or bilateral non-Hodgkin's lymphomas arising primarily in the adrenal glands are extremely rare. These lymphomas are usually present with large, bilateral adrenal masses with or without lymphadenopathy, and may be accompanied by adrenal insufficiency in some cases. A review of the literature indicates that patients with primary lymphoma of the adrenal glands usually do not have disease elsewhere, and if present, it is frequently extranodal. We report here an unusual case of primary bilateral adrenal lymphoma with partial adrenal insufficiency.

Non-neoplastic lesions were added in the 5th edition WHO classification of adrenal cortical tumor based on the recent update, including adrenal rests, adrenal cysts, congenital adrenal hyperplasia and adrenocortical nodular disease. A range of tumor concepts were updated or refined based on tumor cell origin, histopathology, oncology and molecular biology. The most significant nomenclature change in the field of adrenal cortical pathology involves the refined classification of adrenal cortical nodular disease, which now includes sporadic nodular adrenocortical disease, bilateral micronodular adrenal cortical disease, and bilateral macronodular adrenal cortical disease. The 5th edition WHO classification endorses the nomenclature of the HISTALDO classification to help the classification of aldosterone producing adrenal cortical lesions, which uses CYP11B2 immunohistochemistry to identify functional sites of aldosterone production. The 5th edition WHO classification does not change the Weiss and Lin-Weiss-Bisceglia histopathologic criteria for diagnosing adrenal cortical carcinomas, and underscores the diagnostic and prognostic impact of angioinvasion in these tumors. Reticulin algorithm and Helsinki scoring system were added to assist the differential diagnosis of adrenal cortical neoplasms in adults. Pediatric adrenal cortical neoplasms are assessed using the Wieneke system. The 5th edition WHO classification places an emphasis on an accurate assessment of tumor proliferation rate using both the mitotic count (mitoses per 10 mm²) and Ki-67 labeling index which play an essential role in the dynamic risk stratification of affected patients. This review highlights advances in knowledge of histological features, ancillary studies, and associated genetic findings that increase the understanding of the adrenal cortex pathologies in the 5th edition WHO classification.

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.

PURPOSE: Various causes may be the etiology of gynecomastia. We investigated the levels of serum estradiol (E2), testosterone (T), ratio of E2 to T (E2/T) as well as associated diseases, drugs as the cause of gynecomastia. MATERIALS AND METHODS: E2, T, E2/T in 37 patients from gynecomastia patients (GP) and 10 healthy men were measured, and the associated diseases and drugs in 68 GP were also evaluated. Ultrasound for the adrenal gland diseases, physical examination or ultrasound for the testicular pathology were performed. RESULTS: The cause of gynecomastia varied according to the age. The levels of E2, T, E2/T in control group (CG) were 35.3 3.9 pg/ml, 5.0 0.4 ng/ml, 7.1 0.5. Those in GP were 48.7 7.1 pg/ml, 4.3 0.3 ng/ml, 12.0 1.8, respectively. The difference of E2/T as well as E, T between CG and GP was not significant. Various associated diseases or drugs were found in GP. Adrenal diseases or testicular cancer were not found in GP. CONCLUSIONS: The difference of E2/T between CG and GP is not the only cause of gynecomastia. Thus, the consideration of the age as well as associated diseases or drugs will be helpful for the better understanding of high E2/T as the cause of gynecomastia

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.

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.

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.

OBJECTIVETo analyze the change in the incidence of pheochromocytomas in adrenal medulla or extra-adrenal and multiple endocrine neoplasm type 2 (MEN2), to summarize the clinical characteristics of benign, potentially malignant and malignant pheochromocytomas and to investigate the correlation between clinical manifestations and pathological changes.

METHODSStatistic analysis was performed to detect the incidence, constituent ratio, mean diagnostic age, sex proportion and correlation between clinical manifestions and pathologic changes in pheochromocytomas in adrenal medulla or extra-adrenal gland and MEN2 from 1993 to 2008 in the Department of Pathology, the General Hospital of Tianjin Medical University with Runs test, ANOVA, t test and chi-square test.

RESULTSThe total number of biopsies within the 16 years was 167 702 cases (average 10 481 cases per year). The numbers (detectable rate) of total adrenal diseases, pheochromocytomas in adrenal medulla and extra-adrenal glands were 910 (0.54%), 139 (0.08%), and 42 (0.03%) cases, respectively. The numbers (constituent ratio) of benign, potentially malignant and malignant of pheochromocytomas in adrenal medulla were 102 cases (73.4%), 29 cases (20.9%) and 8 cases (5.7%), respectively; in the 102 cases of benign tumors, patients with MEN2 were 8 (7.8%); the three groups of the tumors in extra-adrenal sites were 18 (42.8%) cases, 12 (28.6%) cases and 12 (28.6%) cases. There were no changes in the detectable rate and constituent ratio of adrenal diseases, benign, potential malignant and malignant pheochromocytomas in adrenal medulla or extra-adrenal glands and patients with MEN2 during the past 16 years (P > 0.05), but there was a tendency that malignant transformation was gradually increased with age, which was more commonly found in male patients than females. The mean age at diagnosis of patients with benign and potentially malignant pheochromocytomas was 42.7 years (ranged from 10 - 74 years), and 40.1 years (13 - 66 years), respectively, which were younger than patients with malignant pheochromocytomas (51.6 years, P < 0.05); the mean age of patients with benign and potentially malignant pheochromocytomas in extra-adrenal sites was 43.1 years (ranged from 20 - 75 years) and 45.2 years (28 - 65 years) that were older than those with malignant (37.8 years, ranged from 14 - 58 years, P < 0.05). It was spectacular that patients with malignant pheochromocytoma in adrenal medulla (51.6 years) were older than that in extra-adrenal sites (37.8 years); all the patients with MEN2 were female benign pheochromocytoma in adrenal medulla, whose age (38.9 years) was younger than that of benign lesions (42.7 years, P < 0.05), in which thyroid medullary carcinoma appeared early than pheochromocytomas in adrenal medulla. The detectable rate of hypertension in patients with malignant pheochromocytomas in adrenal medulla and in extra-adrenal sites were less than that in benign and potentially malignant ones (P < 0.05). The bilateral lesions more commonly found in malignant pheochromocytoma (25.0%) than benign (15.7%) and potentially malignant pheochromocytomas (6.9%) only in adrenal medulla. Relapse rates in both adrenal and extra-adrenal tumors were rising from benign (11.8%, 0), potentially malignant (13.8%, 25.0%), to malignant (33.3%, 37.5%) groups; the average diameter of pheochromocytomas in both adrenal and extra-adrenal sites was increasing from benign (4.2 cm, 4.0 cm), potentially malignant (5.3 cm, 5.6 cm) to malignant (7.3 cm, 6.9 cm) groups (P < 0.05).

CONCLUSIONSThe diagnostic criteria of benign, potentially malignant and malignant pheochromocytomas in adrenal medulla and in extra-adrenal sites are well established according to the WHO classification of endocrine tumors (2004). The closer relationship is found between clinical manifestations and pathologic changes. The definite type and nature of pheochromocytomas are mainly rested upon the pathologic examination.
