“…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 ]. Among cases presenting with gastrointestinal bleeding, useful tools for workup appear to be blood scintigraphy or angiography [ 19 ].…”

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.

“…Most schwannomas of the small intestine are found by accident during imaging studies [4] . Abdominal pain [12] and melena [2] , [3] are relatively common symptoms of schwannoma of the small intestine. Some develop into intussusception, although this is rare [13] , [14] .…”

“…Therefore, distinguishing between schwannoma and other malignant tumors, including malignant schwannoma, is almost impossible [9] , [10] . Diagnosis by endoscopy, including DBE, is also not possible because intestinal schwannoma can appear as a submucosal tumor with a non-specific morphology [3] . Thus, surgical resection is essential for accurately diagnosing and treating intestinal schwannomas.…”
