The retroperitoneum is a closed space harbouring vital organs including the great vessels, kidneys and adrenal glands, ureters, and the ascending and descending colon. Surgical management of retroperitoneal pathologies may need multiorgan resection in order to achieve complete surgical resection while preservation of surrounding organs should be attempted, especially in case of benign tumors. We present a case of 15-year-old girl with an 11 × 6 × 5 cm retroperitoneal ganglioneuroma displacing the right kidney, renal vein, and ureter and abutting the IVC which was excised in toto preserving the right kidney and ureter with careful dissection around the great vessels...

BACKGROUND: Ganglioneuromatous polyposis (GP) is a very rare disorder which may be associated with other clinical manifestations and syndromes, such as Cowden syndrome, multiple endocrine neoplasia (MEN) type II and neurofibromatosis (NF) 1. The risk for malignant transformation of ganglioneuromas is unknown, and the combination of GP with colon cancer has been only very seldom reported. METHODS AND RESULTS: We report the case of a 60-year old male patient with adenocarcinoma, adenomas and lipomas of the colon and multiple gastroduodenal lesions combined with generalised lipomatosis and macrocephaly...

Hamartomatous polyposis syndromes (HPS) account for a small but appreciable proportion of inherited gastrointestinal cancer predisposition syndromes; patients with HPS have an increased risk for colon and extracolonic malignancies. We present a unique case of familial juvenile polyposis syndrome associated with gastrointestinal ganglioneuromas of unknown etiology. The patient was tested for HPS-associated genes, but no mutation was detected. Exome sequencing identified a germline heterozygous mutation in SMAD9 (SMAD9(V90M))...

Ganglioneuromas (GNs) are hamartomatous tumors derived from the autonomic nervous system. It is rare to encounter GN in the gastrointestinal tract. Patients with these tumors usually present with abdominal pain, constipation, ileus, weight loss, or even bleeding. GNs are categorized into three different morphological subtypes, namely, polypoid GN, ganglioneuromatous polyposis, and diffuse ganglioneuromatosis. We present a case of hematochezia from GN in a colon polyp discovered on diagnostic colonoscopy. Due to a lack of guidelines, we reviewed the literature to discuss treatment and other associated conditions for GN...

Perineurioma is a rare benign peripheral nerve sheath tumor featuring perineurial differentiation. Perineurioma occurs sporadically with only one reported case in the setting of neurofibromatosis type 1 (NF-1). We present a 6.7-cm soft tissue perineurioma of the lower leg in a 51-year-old man with proven NF-1. The tumor displayed whorled and fascicular pattern with infiltrative margins and expressed EMA, GLUT-1, claudin-1, and CD34. Electron microscopy confirmed diagnosis. Furthermore, lipomatosis, cutaneous angiomatous nodules, vasculopathy, and iliac spine lesion consistent with non-ossifying fibroma were observed...

AIMS: Diffuse neurofibromatosis/ganglioneuromatosis, solitary/plexiform neurofibroma, periampullary carcinoids and gastrointestinal stromal tumour (GIST) are the main gastrointestinal manifestations of neurofibromatosis type 1 (NF-1, von Recklinghausen disease). Inflammatory (juvenile-like) polyps have not been recognised to date as specific gastrointestinal (GI) manifestations of NF-1. METHODS AND RESULTS: We describe four males aged 23-65 years with NF-1 and inflammatory (juvenile-like) gastrointestinal polyps, and review the literature for similar cases...

BACKGROUND: Mesenchymal colorectal polyps are uncommon lesions, particularly those of neurogenic origin. We describe a mucosal Schwann cell hamartoma of the colon with tactoid features, so far reported in peripheral nerve sheath tumours, and address its differential diagnosis and clinical implications. CASE PRESENTATION: A 72-year-old man underwent screening colonoscopy that presented a 5-mm polyp on distal sigmoid. Histologically, it displayed a lesion in the lamina propria comprising oval structures with tactoid features and bland spindle cells, entrapping adjacent crypts...

Ganglioneuroma (GN) is a benign neoplasia of the autonomous nervous system, colonic GN is uncommon in adults. There are three subgroups: polypoid GN, ganglioneuromatous polyposis and diffuse ganglioneuromatosis. Ganglioneuromatosis is highly-associated to neurofibromatosis type 1 (NF1) and multiple endocrine neoplasia type 2b (MEN2B). A 68-year-old female, with a discrete retarded emission of stools, was admitted for a large tumor in the left flank; CT scan, urography and barium enema demonstrated a large retroperitoneal mass, presumed as sarcoma...

Glycosphingolipids (GSLs) are neoplastic and normal/cancer stem cell markers and GSL/cholesterol-containing membrane rafts are increased in cancer cell plasma membranes. We define a novel means by which cancer cells can restrict tumor-associated GSL immunoreactivity. The GSL-cholesterol complex reorients GSL carbohydrate to a membrane parallel, rather than perpendicular conformation, largely unavailable for antibody recognition. Methyl-β-cyclodextrin cholesterol extraction of all primary human tumor frozen sections tested (ovarian, testicular, neuroblastoma, prostate, breast, colon, pheochromocytoma and ganglioneuroma), unmasked previously "invisible" membrane GSLs for immunodetection...

Ganglioneuroma of the gastrointestinal tract is an extremely rare neuroectodermal tumor that can be located in the colon. In clinical practice, it is usually associated with a systemic disease. Herein, we report a case presented with intermittent rectal bleeding and finally diagnosed with ganglioneuromatous polyposis and multiple adenomatous polyps in the colon. We also discuss the patients reported in the pertinent literature.

A 7 year old male with a history of congenital neutropenia and growth hormone deficiency presented with abdominal pain, fevers, and diarrhea. Imaging and endoscopy revealed significant inflammation of the ascending colon with stenosis at the level of the hepatic flexure. A right hemicolectomy was performed, and pathologic findings were consistent with diffuse intestinal ganglioneuromatosis. Due to recurrent mass effect at the intestinal anastomotic site detected radiologically, a second intestinal resection was performed 7 months later...

BACKGROUND & AIMS: Gastrointestinal polyposis is a common clinical problem, yet there is no consensus on how to best manage patients with moderate-load polyposis. Identifying genetic features of this disorder could improve management and especially surveillance of these patients. We sought to determine the prevalence of hamartomatous polyposis-associated mutations in the susceptibility genes PTEN, BMPR1A, SMAD4, ENG, and STK11 in individuals with ≥5 gastrointestinal polyps, including at least 1 hamartomatous or hyperplastic/serrated polyp...
