“…18 The differentiation of schwannomas from other stromal tumours is important because the latter group has high-risk of malignant behaviour. 19 Immunohistochemical studies of GANTs have usually demonstrated positivity to vimentin, CD34 and CD117 5,10,20 Positive reactivity with neuron specific enolase (NSE), S-100 protein, synaptophysin, and chromogranin A (proteins expressed by neurons from the autonomic nerve plexus) have also been reported and this support the histogenesis of GANTs from the autonomic plexus of Meissner or Auerbach. 5 GANT is an ultrastructural variant of GIST, based on its consistent CD117 positivity and the presence of GIST-specific c-kit gene mutations has shown in significant number of cases [21] .…”

Gastrointestinal autonomic neural tumour of colon: a case report of rare unusual tumour of colon

et al. 2016

Gastrointestinal autonomic nerve tumours (GANTs) are uncommon stromal tumors of the intestinal tract. They can involve any part of the gastrointestinal system, but are very rarely seen in the Colon. We report a unique case of Gastrointestinal Autonomic Neural Tumour (GANTs) of colon extending from ascending colon to 2/3rd of the transverse colon. A 50-year-old male patient was admitted with complaint of pain in right side of abdomen. USG revealed f/s/o lymphoma/Carcinoma Colon. CECT Abdomen revealed? Lymphoma? Carcinoma extending from ascending colon to 2/3rd of the transverse colon with Lymphadenopathy. Exploratory Laparotomy was performed followed by Right Hemicolectomy. Histopathology and Immunohistochemistry confirmed the colonic lesion to be a Gastrointestinal Autonomic Neural Tumour. Literature review of the few reported cases has suggested radical surgical excision to be the best approach. Prognosis tends to be favourable after resection.

“…The presence of gastric ulceration has no importance in determining the biological potential, although may be related to tumor size. The most common localization of tumors is in the stomach (12 cases), small intestine (20 cases) [4], and esophagus (2 cases), but they may extend along the entire intestinal tract, even into the retroperitoneal space (3 cases), mesentery (3 cases), bladder (2 cases) [5], colon [6,7], and rectum [8]. The literature to date supports an age range of 10 to 85 years, with a median age of 61 years.…”

Surgical treatment of gastrointestinal autonomic nerve tumors (GANT) in children-2 case reports

AbstractGastrointestinal autonomic nerve tumors form an uncommon subcategory of stromal tumors of the intestinal tract although their histologic appearance is similar to other gastrointestinal stromal tumors. Our aim was to evaluate our experience in the diagnosis and therapy of these kinds of tumors. Two patients were admitted to the Pediatric Surgery Clinic in Niš with abdominal pain and a palpable mass in the abdomen. After excision, the tumor tissue was sampled, sent for histopathological diagnosis, and examined by light microscopy, immunohistochemistry, and electron microscopy. Postoperatively, both patients recovered without complications. The patient with the tumor bulk in the mesentery of the small bowel had no evidence of tumor progression 6 years after surgery. In the second case, a giant tumor was present along the greater curvature of gaster. Even with a tumor of this size, there were no signs of progression 10 years after surgery. Radical surgical resection of gastrointestinal autonomic nerve tumors seems to be the curative approach to date, and long-term survival is possible even with large tumors.

Stromal tumor of duodenal autonomous nerves (plexosarcoma)

et al. 2007

Gastrointestinal tumours arising from autonomous nerves of Meisner's or Auerbach's plexus (plexomas and plexosarcomas) are rare tumours in only 87 cases described in the literature up to 2001. We present a very rare case of gastrointestinal stromal tumour (plexosarcoma) of the third and fourth portion of the duodenum, 130 x 98 x 87 mm in diameter, arising from its back wall, with central necrosis of the well circumscribed tumour, which communicated with the duodenum through an ulceration of 15 x 7mm in diameter, spreading towards the great vessels of the retroperitoneum. It was gradually and carefully removed, together with 17 cm of the duodenum and few centimetres of the jejunum with end-to-end duodenojejunostomy below the Vater's papilla. During the removal of the tumour, the superior mesenteric artery, being within the tumour's capsule, was accidentally ligated but not transsected. In spite of the removal of the ligature, the artery became thrombosed due to damage of the intima by ligature so that it had to be resected and reanastomosed. After otherwise uneventful recovery, except for a mild pus discharge through the drain, not far from the arterial anastomosis, the patient suddenly started bleeding on the 13th day after surgery. At emergency reoperation, a rupture of the mesenteric artery above the thrombosed anastomosis was found. In spite of absence of the arterial pulsation within the mesentery, the bowel looked vital and the back flow from the artery was satisfactory. The arterial rereconstruction was not possible, so the artery was ligated. The postoperative recovery was surprisingly uneventful. The patient was discharged ten days after surgery and has stayed symptom-free so far.
