Ganglioneuroma (GN) is benign tumor arising from sympathetic ganglion which commonly occurs at posterior mediastinum, retroperitoneum and adrenal gland. Rarely, it may also present in cervical region as slow growing painless neck mass. Here we present a 7 years old female child with 4 years duration of slow growing left lateral neck mass. After proper investigations the patient was prepared & taken to the operation room for complete excision of the mass. Post operation biopsy settled the definitive diagnosis as Ganglioneuroma...

Ganglioneuromas are a very rare benign neural tumor, commonly derived from the ganglia of the sympathetic system, and are composed of mature Schwann cells, ganglion cells, and nerve fibres. They may arise anywhere from the base of the skull to the pelvis along the paravertebral sympathetic plexus. We report a rare case of synchronous ganglioneuroma and schwannoma, mistaken for carotid body tumor. The coexistence of these two entities in head and neck region is very rare.

Aberrant expression of thyroid transcription factor-1 (TTF-1) has been observed in tumors arising in locations other than thyroid gland, lung and ventral forebrain. However, TTF-1 expression in schwannomas has not yet been studied. Meanwhile, a few inconsistent changes in protein expression have been identified between schwannomas and other peripheral nerve sheath tumors. We evaluated TTF-1 expression in 161 schwannomas and 43 other peripheral nervous system lesions, including ganglioneuromas (n=8), malignant peripheral nerve sheath tumors (MPNSTs) (n=11), neurofibromas (n=24), and traumatic neuromas (n=9), using immunohistochemistry and verified it using quantitative real-time reverse transcription polymerase chain reaction (qPCR) to explore TTF-1 expression in peripheral nervous system lesions...

Cancer and autoimmunity come together in paraneoplastic syndromes (PNS), which reflect the remote, not direct, effects of cancer. In the pediatric population, a variety of PNS have been described, but the most common of these rare disorders are instigated by neuroblastic tumors, such as neuroblastoma, ganglioneuroblastoma, and ganglioneuroma. The main pediatric-onset neurological PNS are ROHHAD syndrome, anti-ANNA1 (anti-Hu), and opsoclonus-myoclonus syndrome. They manifest distinctive neurological features, which aid the diagnosis, though under-recognition still poses serious challenges and risks...

BACKGROUND: The prognosis of solid pediatric tumors strongly correlates with accurate staging and complete local control. Currently, surgeons rely on macroscopic cues and intraoperative cryosection to determine resection borders. Multiphoton Microscopy (MPM) is a real time technique that allows imaging of tissue without time-consuming tissue processing. PURPOSE: This pilot study evaluates the diagnostic potential of MPM in pediatric solid tumors compared to routine histopathology...

Ganglioneuromas are very rare clinical entities, and their occurrence in the large bowel lays further emphasis on their rarity. Ganglioneuromas are benign tumors of undifferentiated neural crest cells. Their clinical presentation is mostly asymptomatic, and if any symptoms are present at all, they are usually nonspecific, with excellent prognosis. We report an asymptomatic, 65-year-old male with a solitary ascending colonic polyp found on screening colonoscopy. Histology revealed benign polypoid spindle-cell proliferation as well as S100 reactivity, consistent with ganglioneuroma...

The adrenal glands in children can be affected by a variety of benign lesions. The diagnosis of adrenal lesions can be challenging, but assessment of morphologic changes in correlation with the clinical presentation can lead to an accurate diagnosis. These lesions can be classified by their cause: congenital (eg, discoid adrenal gland, horseshoe adrenal gland, and epithelial cysts), vascular and/or traumatic (eg, adrenal hemorrhage), infectious (eg, granulomatous diseases), enzyme deficiency disorders (eg, congenital adrenal hyperplasia [CAH] and Wolman disease), benign neoplasms (eg, pheochromocytomas, ganglioneuromas, adrenal adenomas, and myelolipomas), and adrenal mass mimics (eg, extralobar sequestration and extramedullary hematopoiesis)...

Presacral ganglioneuromas are extremely rare benign tumors and fewer than 20 cases have been reported in the literature. Ganglioneuromas are difficult to be differentiated preoperatively from tumors such as schwannomas, meningiomas, and neurofibromas with imaging modalities. The retroperitoneal approach for resection of presacral ganglioneuroma was performed for gross total resection of the tumor. Recurrence and malignant transformation of these tumors is rare. Adjuvant chemotherapy or radiation therapy is not indicated because of their benign nature...

BACKGROUND: This study evaluated the utility of Phox2b in pediatric tumors. Previously tyrosine hydroxylase (TH) was the most widely utilized sympathoadrenal marker specific for neural crest tumors with neuronal/neuroendocrine differentiation. However, its sensitivity is insufficient. Recently Phox2b has emerged as another specific marker for this entity. METHODS: Phox2b IHC was performed on 159 pediatric tumors including (1) 65 neural crest tumors with neuronal differentiation [peripheral neuroblastic tumors (pNT)]: 15 neuroblastoma undifferentiated (NB-UD), 10 NB poorly differentiated (NB-PD), 10 NB differentiating (NB-D), 10 ganglioneuroblastoma intermixed (GNBi), 10 GNB nodular (GNBn), and 10 ganglioneuroma (GN); (2) 23 neural crest tumors with neuroendocrine differentiation [pheochromocytoma/paraganglioma (PCC/PG)]; (3) 27 other neural crest tumors including one composite rhabdomyosarcoma/neuroblastoma; and (4) 44 non-neural crest tumors...

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)...

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...
