We describe the case of a 71-year-old man with a ganglioneuroma of the retropharyngeal space. The patient presented with a submucosal bulge of the left oropharyngeal wall during follow-up examination of a treated vocal cord carcinoma. CT and MRI revealed a non-specific, well-defined retropharyngeal soft tissue lesion. Positron emission tomography-CT did not show relevant metabolic activity, excluding the hypothesis of metastatic nodal disease. Surgical biopsy of the lesion was compatible with ganglioneuroma...

Peripheral nerve sheath tumors (PNST) are exceedingly rare, especially outside of the posterior mediastinum. These tumors represent less than 1% of pulmonary tumors. Very few pulmonary PNSTs are ganglioneuromas. We present a case of a ganglioneuroma presenting as an endobronchial mass. CASE PRESENTATION: An 80 year old male was seen in pulmonary clinic for routine cancer screening. He had a 60-pack year smoking history. CT evaluation noted a 1cm right lower lobe endobronchial lesion. This lesion was present since 2012 and had slightly increased in size since that time from 8mm (Figure 1)...

OBJECTIVE: We report an extremely rare case of ganglioneuroma involving the external auditory canal and middle ear. CASE REPORT: Ganglioneuromas are rare benign mature tumors thought to originate from sympathetic ganglions, with the highest incidence in the retroperitoneum, adrenal medulla, and posterior mediastinum. We present a case of ganglioneuroma of the external auditory canal and middle ear. At the age of 12 months, the patient was diagnosed with neuroblastoma stage IV with metastasis to the squamous temporal bone, bone marrow, and skull base...

PURPOSE: Uveal ganglioneuroma is a rare tumor that usually occurs in association with neurofibromatosis type 1. Here, we present a rare case of a uveal ganglioneuroma leading to a diagnosis of the tumor predisposition condition Cowden syndrome. PROCEDURES: A 5-year-old girl with unilateral refractory glaucoma secondary to diffuse iris and choroidal thickening developed a blind, painful eye. Enucleation was performed, and histopathology revealed infiltration of the entire uveal tract by neoplastic spindle cells containing admixed ganglion cells diagnostic of uveal ganglioneuroma...

BACKGROUND: Composite pheochromocytoma/paragangliomas are very rare tumors composed of ordinary pheochromocytoma paragangliomas associated with neurogenic tumors. Several hereditary susceptibility disorders are known to be associated with pheochromocytoma/paragangliomas such as multiple endocrine neoplasia type 2 (2A or B). To the best of our knowledge, only four cases of composite pheochromocytoma/paragangliomas associated with multiple endocrine neoplasia type 2 have been reported. CASE PRESENTATION: A 40-year-old Arabic woman presented with headache, palpitations, paroxysmal hypertension, and weight loss, which she had had for the last 3 years...

Ganglioneuromas represent the most well-differentiated spectrum of neoplasia arising from the sympathetic nervous system, while neuroblastomas represent the most poorly differentiated counterpart, and ganglioneuroblastomas represent intermediate stages of differentiation. Small series of cases have documented the co-occurrence of ganglioneuroma with a pheochromocytoma (Pheo)/paraganglioma (PGL) component. We report the clinicopathologic features of eight such cases, diagnosed between 2003 and 2015 with a mean follow-up of 22 months (1-47), which were evaluated for syndrome associations, SDHB expression, and clinical outcome...

Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an autosomal dominant disorder characterised by developmental alterations and multiple basal cell carcinomas. Mutations in PTCH1, a membrane receptor for Sonic Hedgehog, are associated with the development of the disease. Most of them produce a truncated protein which is unable to supress Smoothened protein and continuously activates the downstream pathway OBJECTIVES: We aimed to characterize 22 unrelated Spanish subjects with NBCCS, the largest cohort of Gorlin syndrome reported to date in Spain METHODS AND RESULTS: We reported for the first time two young patients with uterus didelphys and ganglioneuroma, within the context of NBCCS...

Chronic diarrhea in infants is a common condition for addressability to pediatric gastroenterologists. The causes are multiple and the delay in reaching the final diagnosis can lead to complications in the general condition of the child. The purpose of this review is to present the bio-clinical and histogenetic particularities of a rare clinical entity, characterized by tumoral causes of chronic diarrhea. VIPomas are neuroendocrine tumors that autonomously secrete vasoactive intestinal peptide (VIP). Watery diarrhea, hypokalemia and achlorhydria (WDHA) syndrome caused by VIP-producing tumors only rarely occurs in adult patients with non-pancreatic disease...

Mature teratomas are the most common ovarian neoplasms, accounting for 40% to 50% of ovarian tumors, and are histologically defined by the presence of multiple lineages of mature differentiated cells derived from one or more of the 3 embryonic germ layers; ectoderm, mesoderm, and endoderm. Neuroectodermal and neural crest differentiation can be observed in mature teratomas, but it is uncommon to find secondary tumors that arise from the neural crest lineage. Herein we report the uncommon finding of a ganglioneuroma arising in a mature cystic teratoma in a 26-yr-old woman...

BACKGROUND: Ganglioneuroma (GN) is a rare benign tumor arising from the neural crest cells. The reported incidence of GN is one per million population. As a primary retroperitoneal tumor, it constitutes only a small percentage of 0.72 to 1.6%. GN can arise de novo or as a result of maturation of a neuroblastoma either spontaneously or after chemotherapy. The most common location is the posterior paraspinal mediastinum, retroperitoneum, neck and adrenal gland. However, GN can potentially occur anywhere along the peripheral autonomic ganglion sites...

Here we report the case of a 30-year-old woman with a history of neurofibromatosis type 2 (NF2) who presented with an incidentally discovered pelvic mass on an ultrasound. The identity of the mass remained indeterminate following a CT and MRI, although appendiceal pathology was suspected. An elective laparoscopy and appendectomy were performed without complication and pathology on the specimen demonstrated an appendiceal ganglioneuroma. To our knowledge, there has been no prior documented case of an appendiceal ganglioneuroma in a patient with NF2...

BACKGROUND: Minimal access adrenal surgery (MAAS) for adrenal pathologies is the standard for many pediatric surgical centers. However, the literature offers few reports and minimal evidence from small case series. The aim of this study was to evaluate the outcomes of pediatric MAAS through a multi-center data analysis. METHOD: Pediatric patients who underwent MAAS between January 2002 and December 2013 were retrospectively included. Data analysis was conducted using Spss software (Welch's t-test, X-square, Fisher tests, multiple regression model)...

Purpose We explored the diagnostic value of diffusion-weighted MRI (DWI) for tumor characterization, differentiation and therapy monitoring in pediatric patients with extracranial neuroblastic tumors. Materials and Methods All 29 patients (14 girls, median age: 3 years) with neuroblastoma (NB, n = 19), ganglioneuroblastoma (GNB, n = 4) and ganglioneuroma (GN, n = 6) who had had at least one in-house DWI examination since 2005 were identified and retrospectively analyzed. Two independent blinded readers measured ADC values (unit: 10-3 mm(2)/s) and signal intensity ratios (SIRs) of the primary tumor and, if applicable, of the tumor after chemotherapy, metastases and tumor relapse...
