  • Endoscopic Management of Ganglioneuroma in the Stomach. [Case Reports]
    ACG Case Rep J. 2020 May; 7(5):e00382.Ghoneim S, Shah A, … Sandhu D
  • Ganglioneuromas are rare benign tumors of neuroblastic origin that can occur anywhere along the sympathetic chain. They are rarely found in the gastrointestinal tract and can appear as solitary polypoid lesions or diffuse as part of a familial syndrome. They are often asymptomatic but may present with nonspecific symptoms depending on their anatomic location. They have no special endoscopic appea…
  • Multimodal Imaging Features of Bilateral Choroidal Ganglioneuroma. [Journal Article]
    J Ophthalmol. 2020; 2020:6231269.Jiang Z, Zhang T, … Ding X
  • CONCLUSIONS: Choroidal ganglioneuroma is rare. To our knowledge, no bilateral cases have been described in the literature. Major clinical features include a rapid increase in axial length, diffuse choroidal thickening, hyper-reflectivity in the choroid on optical coherence tomography, and loss of choroidal vasculature on ICGA. The current report provides multimodal imaging of choroidal ganglioneuroma for the first time and can be valuable for early diagnosis.
  • Neurogenic Tumors of the Mediastinum. [Review]
    Semin Diagn Pathol. 2020 May 21 [Online ahead of print]Rodriguez EF, Jones R, … Rodriguez FJ
  • Neurogenic tumors represent a broad ill-defined category of neoplasms that includes tumors of Schwann cell and/or neuroblastic derivation, as well as neoplasms that typically develop in the central nervous system, but rarely present in ectopic sites including the mediastinum. Neurogenic tumors may occur at many different anatomic sites, but the mediastinum represents a uniquely challenging site g…
  • Intestinal ganglioneuroma in a neonatal Japanese black calf - Short communication. [Journal Article]
    Acta Vet Hung. 2020 May 04 [Online ahead of print]Sasaki J, Kuroda Y, … Yamagishi N
  • A 1-day-old male calf presented with clinical signs of severe progressive abdominal distension. Abdominal radiographic and ultrasonic images revealed several loop-like structures in the small intestine, which were indicative of gas retention. Experimental laparotomy was performed. However, the calf died during surgery. At necropsy, a round, well-circumscribed mass (3 × 3 × 2.5 cm) was found in th…
  • A giant ganglioneuroma accompanied with scoliosis. [Journal Article]
    Ann R Coll Surg Engl. 2020 Apr 01 [Online ahead of print]Zhang Q, Li F, … Zhao S
  • Ganglioneuroma is a rare benign neoplasm. Patients with ganglioneuroma show no symptoms. We describe a rare case of giant ganglioneuroma with scoliosis in a 35-year-old woman, who presented to our hospital for haemoptysis. We combined with neurosurgeons to remove the tumour successfully. After 16 months of follow-up, there is no evidence of tumour recurrence.
  • Non-adrenal tumors of the adrenal area; what are the pitfalls? [Journal Article]
    J Visc Surg. 2020 Mar 19 [Online ahead of print]Frey S, Caillard C, … Mirallié É
  • Discovery of an adrenal mass is nowadays a frequent situation. While adrenal tumors can cause a variety of symptoms, more often than not they are diagnosed incidentally on imaging exams such as CT-scan or MRI performed for another purpose. However, any retroperitoneal supra-renal mass can have an extra-adrenal origin. Indeed, operated non-adrenal masses initially but wrongly diagnosed as an adren…
  • Role and toxicity of radiation therapy in neuroblastoma patients: A literature review. [Review]
    Crit Rev Oncol Hematol. 2020 May; 149:102924.Zhao Q, Liu Y, … Jiang X
  • Neuroblastoma is the most common extracranial solid tumor, arising from primitive sympathetic ganglion cells, in pediatric patients. The unique features of neuroblastoma include variable clinical behaviors, such as rapid progression to death and maturation to benign ganglioneuroma, followed by regression. Radiation therapy (RT) is usually administered to both the primary tumor bed and persistent …
  • Mediastinal Hibernoma: A Rare Cause of Chronic Cough. [Case Reports]
    Cureus. 2020 Jan 22; 12(1):e6738.Muñoz-Palacio BJ, Figueroa S, … Betancur JF
  • A hibernoma is an uncommon benign soft tissue tumor composed of brown adipose cells; the mediastinal location as presentation is scarce, with only six cases previously reported. The diagnosis of hibernoma is challenging and must be made based on the clinical, radiographic, and cytologic features. Here we present a 33-year-old woman without any relevant medical history presented for outpatient eva…
  • Endoscopic Treatment of Solitary Colonic Ganglioneuroma. [Case Reports]
    Case Rep Gastroenterol. 2020 Jan-Apr; 14(1):34-38.Arai T, Yamada H, … Nakachi K
  • Ganglioneuromas (GNs) in adults are uncommon clinical entities, especially in the colon. Patients with GNs without multiple endocrine neoplasia or neurofibromatosis-I are normally asymptomatic; however, GNs can present with abdominal pain, weight loss, bleeding, and anemia, depending on the size and location. Here, we present a case of solitary colonic GN treated with endoscopic mucosal resection…
  • [Clinicopathological features of composite pheochromocytoma]. [Journal Article]
    Zhonghua Bing Li Xue Za Zhi. 2020 Feb 08; 49(2):145-148.Hu QQ, Qi GW, … He XL
  • Objective: To detect the clinicopathological features, immunophenotype, diagnosis, and differential diagnosis of composite pheochromocytoma(CP). Methods: Five cases of CP were collected at Zhejiang Provincial People's Hospital from January 2011 to January 2019. The clinical, radiological, histologic, immunohistochemical and outcome data were analyzed; the diagnosis and differential diagnosis we…
  • [A Case of Neurofibromatosis Type 1 Presenting Voiding Symptoms Caused by Giant Bladder Diverticulum]. [Case Reports]
    Hinyokika Kiyo. 2019 Dec; 65(12):513-517.Maesaka F, Ohmori C, … Momose H
  • A 40-year-old man complaining of voiding symptoms was referred to our hospital for further examinations and treatment of giant bladder diverticulum and possibly underlying neurogenic bladder dysfunction. Because computed tomography and magnetic resonance imaging revealed the presence of a tumorous lesion covering the bladder diverticulum, transurethral biopsy was performed to elucidate its pathol…
  • Rare Primary Retroperitoneal Neoplasms. [Journal Article]
    Isr Med Assoc J. 2020 Jan; 22(1):53-59.Dayan D, Abu-Abeid S, … Sagie B
  • CONCLUSIONS: Familiarity with radiologic characteristics of PRN is important for appropriate management. Counter to STS, other PRN are mostly benign and have an indolent course. Radical surgery is not required, as complete TR confers good prognosis. Expectant management is reserved for small, asymptomatic, benign neoplasms.
  • A radiological and histological comparison of two unusual adrenal incidentalomas. [Journal Article]
    Malays J Pathol. 2019 Dec; 41(3):327-331.Loong S, Selvarajan S, Khor LY
  • CONCLUSIONS: Both adenomatoid nodule and mature ganglioneuroma are rare benign adrenal tumours that need to be differentiated from other, more common adrenal lesions. The management of adrenal incidentalomas is challenging. Surgical excision is indicated if an adrenal incidentaloma is more than 4 cm in size, shows malignant features on imaging or evidence of hormone excess.
  • Concurrent Adrenal and Extra-Adrenal Ganglioneuromas: A Case Report. [Case Reports]
    Am J Case Rep. 2019 Dec 06; 20:1817-1820.AlGhamdi MH, AlAyed A, … AlRasheed M
  • CONCLUSIONS: Adrenal and extra-adrenal ganglioneuroma can, although rare, concur together. Key findings are the similar radiological appearance of the lesions with typical hypovascular progressive pattern of enhancement. Appropriate pre-surgical diagnosis can aid to proper management since ganglioneuroma needs wide surgical resection due to its high chance of recurrence.
