Objective To evaluate the improvement of diagnosis and treatment of hypercatecholaminism. Methods A total of 95 cases of hypercatecholaminism were reviewed.Of them 74 cases were of pheochromocytoma and 21 cases were of adrenal medullary hyperplasia (AMH).In pheochromocytoma group,67 cases (90.5%) had symptom of hypertension.Increase in 24 h urinary VMA occurred in 62 cases (83.8%) and elevated urinary catecholamine level in 67(90.5%).All thses had positive findings of ultrasound,CT scan and MRI.In AMH group,all the patients were hypertensive and their 24 h urinary VMA was increased.Most of them (15/16) had higher urinary catecholamine level than normal;14 out of the 21 cases had positive findings of B-ultrasound examination. Results Surgical operations were performed in the 74 patients with pheochromocytoma including 9 cases of extra-drenal pheochromocytoma.Of them 5 cases were confirmed as malignant pheochromocytoma.In the 21 cases of AMH,18 undewent surgical operation.Of them 12 received unilateral resection and 6 received bilateral resection of adrenal gland.The pathological examination confirmed the diagnosis of AMH. Conclusions The diagnosis of pheochromocytoma should be focused on endocrinological examination,ie,qualitative examination,whereas it is diffucult to localize the lesion in AMH compared with pheochromocytoma.The establishment of notion of AMH as an isolated clinicopathological entity broadens and perfects the theory of hypercatecholaminism.

Objective Castleman′s disease ( CD) is a rare lymphoproliferative disorder, which has a very high misdiagnosis rate according to its lack of clinical and imaging specificity.The study was to improve the recognition, diagnosis and management of this disease by analyzing the clinicopathological characteristics and concluding diagnosis and treatment as well as literature review. Methods Retrospective analysis was conducted on clinical data of 31 CD patients (13 males and 18 females) who were hospitalized in the Affiliated Drum Tower Hosipital to Medical college of Nanjing University from January 2006 to Feburary 2014.Their mean age was (47.4 ±13.3) years.There were 24 cases with unicentric Castleman′s disease (UCD) and 7 cases with multicentric Castleman′s disease ( MCD) .UCD tended to be present in the form of an enlarged and painless mass which generally remained asymptomatic by accidental touch or regular physical examination.MCD was usually associated with constitutional symptoms.All the 24 patients with UCD underwent complete surgical resection.7 patients with MCD received different treatment methods, such as surgical resection, ste-riod and rituximab in combination with chemotherapy ( CHOP) . Results Postoperative pathology confirmed 23 cases were hyaline vascular type while 8 were plasma cell type.25 cases had been followed up (46.3 ±32.3) months after operation, among which 1 UCD case died of pancreatic head carcinoma 13 months after operation, 1 case with MCD plus pemphigus died 2 months after surgical resection of retroperitoneal lymphadenectasis, another MCD case died in 1 month without any treatment.The remaining 22 cases were alive. Conclusion CD is lack of clinical specificity and its diagnosis should be made by pathology.Each subtype differ greatly in prognosis, therefore different treatments should be taken after definitive subtype diagnosis.

Objective To evaluate the clinical feasibility of laparoscopic cool-tip radiofrequency ablation (LCRFA)for renal cell carcinoma. Methods Twelve selected cases of primary renal, ceil carcinoma underwent LCRFA. Of them, 4 cases of left renal carcinomas, 7 cases had right renal carci-nomas and 1 case had bilateral renal carcinomas. The maximum diameter of the tumors was 2.1-8. 5 era. Eleven cases were T, No M0 and the other one was T2 N0 M0. Results The mean operation time was 92±24 min, and the mean blood loss was 50±29 ml. None of the cases need blood transfusion post-operation. No laparoscopic operative complications were observed. Six weeks after operation, complete ablation was achieved in 12 lesions and partial ablation in 1, with a complete ablation rate of 92.3%(12/13). There was no statistic change of Hb. ESR. SCr and GFR after operations (P>0.05). Ten cases underwent CT examination 3 months after the treatment ,9 cases showed complete necrosis of tumor,1 case showed partial necrosis. No recurrence was found. All of the 12 cases remained sur-vived during the follow-up for 1-16 months(median,7.8 months). Conelusions LCRFA for renal cell carcinoma is an accurate and effective intervention with a low incidence of complications, and is more accurate than ultrasound-guided pereutaneous radiofrequency ablation.
