Harlequin syndrome is a rare disorder of the sympathetic nervous system characterized by unilateral facial flushing and sweating. Although its etiology is unknown, this syndrome appears to be a dysfunction of the autonomic nervous system. To the best of our knowledge, thus far, very few reports on perioperative Harlequin syndrome after thoracic surgery have been published in the thoracic surgical literature. Here, we present the case of a 6-year-old patient who developed this unusual syndrome following the resection of a posterior mediastinal mass.

BACKGROUNDAdrenal ganglioneuroma is a rare adrenal pathogenic disease with difficult differential diagnosis from adrenal pheochromocytoma. Currently, very limited literature is available to allow a differential diagnosis of these two conditions from each other. This study aimed to evaluate the clinical profile, differential diagnosis and surgical treatments of both conditions.

METHODSClinical characteristics of 36 patients with adrenal pheocheomocytoma and 18 patients with adrenal ganglioneuroma were analyzed. Data from CT scans and surgical treatments from 1999 to 2007 were collected. Endocrine hormone tests and (131)I-metaiodobenzylguanidine (MIBG) were performed. Neither (131)I-MIBG nor endocrine hormone tests were available in 9 cases of asymptomatic adrenal ganglioneuroma with tumor size less than 4 cm and there were negative findings from contrast enhanced CT scans. The level of urine catecholamine of patients was compared by one-way analysis of variance.

RESULTSTe mean age of patients in the adrenal ganglioneuroma group was 41.2 years (16 - 67 year) and in the adrenal pheochromocytoma patients 38 years (17 - 74 year). Contrast enhanced CT showed that the foci were intensified in 5 cases (27.8%) of adrenal ganglioneuroma and there were obvious contrast indications in 30 (83.3%) of the pheochromocytoma. Catecholamine levels in a 24-hour urine sample were normal in 4 patients with adrenal ganglioneuroma and increased in 36 (100%) cases with adrenal pheochromocytoma. (131)I-MIBG nuclear scan showed negative results in 4 patients (100%) with adrenal ganglioneuroma and positive results in 25 (96.2%) with adrenal pheochromocytom. Laparoscopy for adrenal tumors was performed through a transperitoneal or retroperitoneal approach during a follow-up period of (43 +/- 6) months, and all cases survived well.

CONCLUSIONSCT, urinary catecholamine and (131)I-MIBG are standard and efficient tools for differential diagnosis of adrenal ganglioneuroma from pheochromocytoma. Laparoscopic surgery can be performed through a transperitoneal or retroperitoneal approach depending on the finding of CT scans. Open surgery is necessary for patients with blood loss of more than 800 ml and violent fluctuation of intraoperative blood pressure.

A case of intracranial ganglioneuroma arising from the trigeminal nerve in the pontine and cerebellopontine angle cistern, in a 44-year-old female, is presented with an emphasis on diffusion-weighted imaging findings. We will discuss on how the tumor in the very unusual location should be differentiated particularly focused on diffusion-weighted imaging findings.

OBJECTIVE: To evaluate clinical feature, diagnosis, treatment and prognosis of ganglioneuroma in the neck. METHOD: The medical records of 6 patients with cervical ganglioneuroma which were confirmed by pathology between 1995 and 2009 were retrospectively reviewed. RESULT: Patients with ganglioneuroma in the neck typically present with an asymptomatic neck mass. Neither imaging procedures nor fine needle aspiration made a definite diagnosis before surgery. All cases were operated, and developed Horner syndrome. With a median follow-up time of 5.9 years, all cases survived without local recurrence or distant metastasis. CONCLUSION Ganglioneuroma in the neck is a rare well differentiated benign tumour. Definite diagnosis only can be made after pathology. Complete surgical excision is the treatment of choice, as it will ensure thorough sampling of the tumour and cure. Postoperative prognosis is favorable if total resection.

OBJECTIVETo summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.

METHODSThe clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.

RESULTSSix operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.

CONCLUSIONGanglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.

BACKGROUND: Mediastinal neurogenic tumors are generally benign lesions and they are ideal candidates for performing resection via video-assisted thoracoscopic surgery (VATS). However, benign neurogenic tumors at the thoracic apex present technical problems for the surgeon because of the limited exposure of the neurovascular structures, and the optimal way to surgically access these tumors is still a matter of debate. This study aims to clarify the feasibility and safety of the VATS approach for performing surgical resection of benign apical neurogenic tumors (ANT). MATERIAL AND METHOD: From January 1996 to September 2008, 31 patients with benign ANT (15 males/16 females, mean age: 45 years, range: 8~73), were operated on by various surgical methods: 14 VATS, 10 lateral thoracotomies, 6 cervical or cervicothoracic incisions and 1 median sternotomy. 3 patients had associated von Recklinhausen's disease. The perioperative variables and complications were retrospectively reviewed according to the surgical approaches, and the surgical results of VATS were compared with those of the other invasive surgeries. RESULT: In the VATS group, the histologic diagnosis was schwannoma in 9 cases, neurofibroma in 4 cases and ganglioneuroma in 1 case, and the median tumor size was 4.3 cm (range: 1.2~7.0 cm). The operation time, amount of chest tube drainage and the postoperative stay in the VATS group were significantly less than that in the other invasive surgical group (p<0.05). No conversion thoracotomy was required. There were 2 cases of Hornor's syndrome and 2 brachial plexus neuropathies in the VATS group; there was 1 case of Honor's syndrome, 1 brachial plexus neuropathy, 1 vocal cord palsy and 2 non-neurologic complications in the invasive surgical group, and all the complications developed postoperatively. The operative method was an independent predictor for postoperative neuropathies in the VATS group (that is, non-enucleation of the tumor) (p=0.029). CONCLUSION: The VATS approach for treating benign ANT is a less invasive, safe and feasible method. Enucleation of the tumor during the VATS procedure may be an important technique to decrease the postoperative neurological complications.

OBJECTIVETo study the clinicopathologic characteristics of peripheral neuroblastic tumors and to investigate the prognostic significance of International Neuroblastoma Pathology Classification (INPC).

METHODSOne hundred and thirty-five cases of peripheral neuroblastic tumors encountered in Shanghai Children's Medical Center were enrolled into the study. All the cases were classified according to INPC and International Neuroblastoma Staging System (INSS). The follow-up data were analyzed.

RESULTSThe consensus diagnoses of the 135 cases were as follows: 80 cases (59.2%) of neuroblastoma, 24 cases (17.8%) of ganglioneuroblastoma, intermixed, 17 cases (12.6%) of ganglioneuroma and 14 cases (10.4%) of ganglioneuroblastoma, nodular. The cases were subdivided into 2 subgroups: favorable histology (number = 90, 66.7%) and unfavorable histology (number = 45, 33.3%). According to INSS, the number of cases in stages I, II, III and IV was 22 (16.3%), 24 (17.8%), 34 (25.2%) and 55 (40.7%), respectively. The survival of peripheral neuroblastic tumors correlated with histologic diagnosis, INPC and INSS (P < 0.05).

CONCLUSIONDiagnostic categorization of peripheral neuroblastic tumors according to INPC is of prognostic value.
