“…Since the findings of small bowel schwannomas are extremely rare, their incidence in the population is unclear and has only been estimated in some existing studies [2,7]. In the current digital literature, we found that only a few small bowel schwannomas have been described [2,7,[12][13][14][15][16][17][18][19][20][21][22] that localised to the duodenum, jejunum, or ileum. The majority of patients (about 2/3) were females.…”

The incidence of small bowel schwannomas is extremely low. In the current literature, we found just a few reported small intestine schwannomas that were located in the duodenum, jejunum, or ileum. This study reports a surprising finding of a relatively large size ileal schwannoma in a patient whose preoperative magnetic resonance imaging described a tumour in the lesser pelvis probably derived from the right adnexa. Pfannenstiel incision was made by the gynaecology team, which found a large mass lesion arising from the small intestine and occupying nearly the entire lesser pelvis. The general surgeon was invited, and pathology was successfully managed by segmental resection of the small bowel with primary end-to-end anastomosis. The histopathology study reported a submucosal tumour composed of S-100 protein-positive spindle cells, and the diagnosis of ileal schwannoma was made. The possibility of intestinal neoplasms, including schwannomas, might be contemplated in the differential diagnosis of any pelvic mass lesions. A detailed histology study and immunohistochemical stain are required for the final diagnosis of intestinal schwannomas and to rule out malignant changes, which are extremely important for the further management of patients. To the best knowledge, our case is one of the biggest intestinal schwannomas reported in the current literature.

“…The symptoms are nonspecific and vague [ 2 – 5 , 7 , 12 , 15 ]. Depending on the location of the tumor growth and development, the patient can present with atypical abdominal pain, melena, mass palpation, and, rarely, intestinal obstruction [ 1 , 6 , 14 – 16 ]. The presenting symptom of gastrointestinal bleeding could be due to the growing submucosal mass abundant in blood vessels, which at some point extends its vascular supply, leading to ischemic tissue formation that ulcerates and bleeds [ 3 , 11 , 17 ].…”

“…Preoperative diagnosis of schwannoma is challenging because there are no disease-specific symptoms or imaging studies showing distinct features unique to this tumor. The most common modalities of imaging, such as CT, magnetic resonance imaging, ultrasound, and endoscopy, are useful for assessing the location of the tumor, the presence or the extent of the invasion, and revealing any complications [ 5 , 8 , 14 – 15 ,]. In addition, it has been reported that a jejunal mass, which proved to be schwannoma, had been identified by the use of video capsule endoscopy [ 18 ].…”

Patient: Female, 57-year-old Final Diagnosis: Jejunal schwannoma Symptoms: Asymptomatic Clinical Procedure: — Specialty: Surgery Objective: Rare disease Background: Schwannomas are tumors that arise from Schwann cells that surround and support nerve cells. Most common sites for presentations are head, neck, and extremities. Schwannomas of gastrointestinal tract are rare, slow-growing tumors, usually benign, arising from gastrointestinal tract’s neural plexus. They are histologically distinguishable from conventional schwannomas that arise in soft tissue or the central nervous system. Preoperative diagnosis of gastrointestinal schwannoma is challenging, requiring immunohistological confirmation of the nature of the tumor. Here, we report a case of 57-year-old woman with an incidental finding of an asymptomatic submucosal jejunal schwannoma. Case Report: A 57-year-old woman with a medical history of hematological disorder underwent a contrast abdominal computed tomography as part of medical follow-up. The imaging revealed the presence of a jejunal mass. The patient underwent laparoscopic surgical resection of the lesion, followed by side-to-side jejuno-jejunal anastomosis with 4-cm clear surgical margins. The final pathologic study revealed the presence of jejunal schwannoma, as tested positive for S-100 protein. The patient was discharged home on the fourth postoperative day, having an uneventful recovery. Conclusions: Jejunal schwannoma are usually benign and asymptomatic, and they are often discovered incidentally during diagnostic tests for other conditions; therefore, it should be included in the differential diagnosis of gastrointestinal tumors. Surgical treatment appears to be necessary to achieve a definitive diagnosis through a biopsy of the tumor tissue. Benign jejunal schwannomas have a good prognosis.

Ileal schwannoma causing intussusception in an adult

et al. 2018

View full text Add to dashboard Cite

Ileal schwannomas are extremely rare tumours. Very few cases have been previously reported. Most cases present with abdominal pain and gastrointestinal bleeding; intussusception is a rare presentation. Due to limitations in imaging modalities, arriving at a diagnosis preoperatively can be challenging. The only reliable method of diagnosis, and treatment, is resection of the tumour, followed by histological and immunohistochemical testing. This report details the rare case of intussusception as the presenting feature of an ileal schwannoma.
