We demonstrate a 4-year-old girl who presented with progressive, asymmetrical, firm abdominal distention and was diagnosed with synchronous Wilms' tumor and left para-aortic ganglioneuroma (GN). Although synchronous tumors in the pediatric population are commonly associated with malignancy-predisposing syndromes, the patient in question was found to be otherwise healthy and had no clinical evidence nor family history of a syndrome. This case is the second one in the literature diagnosed with synchronous presentation of Wilms' tumor and GN in a previously healthy child...

REVIEW
Garrett M Brodeur
Neuroblastomas are characterized by heterogeneous clinical behavior, from spontaneous regression or differentiation into a benign ganglioneuroma, to relentless progression despite aggressive, multimodality therapy. Indeed, neuroblastoma is unique among human cancers in terms of its propensity to undergo spontaneous regression. The strongest evidence for this comes from the mass screening studies conducted in Japan, North America and Europe and it is most evident in infants with stage 4S disease. This propensity is associated with a pattern of genomic change characterized by whole chromosome gains rather than segmental chromosome changes but the mechanism(s) underlying spontaneous regression are currently a matter of speculation...

Neural lesions of the colon may be masses (schwannomas and neurofibromas) or, more frequently, small polyps including perineuromas, ganglioneuromas and granular cell tumors. Some neural lesions are associated with congenital syndromes (neurofibromatosis-1, multiple endocrine neoplasia-2B). Recently, a new entity has been described named mucosal Schwann cell hamartoma, consisting of an intramucosal neural proliferation; to date, less than forty cases have been reported. We report a further case in a patient from whom a polyp was extirpated during colonoscopy screening...

Chylothorax is a severe condition resulting from the accumulation of chyle into the pleural space. We report the treatment of postoperative chylothorax after resection of mediastinal ganglioneuroma in a 17-year-old boy. Since conservative measures were not effective, we performed direct ligation of lymphatic vessels and pleurodesis. At subsequent surgical re-exploration for persisting chylothorax, accurate inspection of pleural cavity revealed residual chyle leakage. Fibrin sealant patches (TachoSil®) were placed over the source of leak with complete resolution of chylous effusion...

Alpha Fetoprotein (AFP) producing gastric carcinomas are very rare and have unique clinicopathological features and an extremely poor prognosis. Here, we report a case of AFP producing gastric carcinoma with three distinct histomorphologic patterns such as yolk sac like, hepatoid, tubular and papillary adenocarcinoma components. The uniqueness of this case is absence of metastases and associated findings such as fundic gland polyposis with varying degrees of dysplasia, gastric and duodenal well differentiated neuroendocrine tumour and rectal ganglioneuroma...

The skin serves as a window for clinicians to understand, diagnose, and monitor endocrine disease. Dermatologic manifestations of endocrinopathies contribute significantly to an individual's health and quality of life. In this review, we outline various disorders of the hypothalamic-pituitary axis, thyroid gland, pancreas, adrenal gland, and androgen axis as well as hereditary endocrine syndromes. In acromegaly, glycosaminoglycan deposition contributes to a thickening of skin and soft tissue, which manifests as coarsening and enlargement of facial and acral structures...

BACKGROUND: Benign neurogenic tumor involving the urinary bladder is a very rare and heterogeneous disease group. The clinical and radiological diagnosis may be difficult because of the disease's rarity and the histological similarities of each disease especially in needle biopsy specimens. However, accurate diagnosis is very important because the clinical course of each disease, even within the same diseases, is quite variable. In this study, we investigated 7 benign neurogenic tumors to better understand the rare disease entity in the urinary bladder by analyzing histological and immunohistochemical findings and comparing clinicopathologic features...

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)...
