Giant Cellular Neurilemmoma, a Rare Mesenchymal Tumor of the Oesophagus: A Case Report

Introduction: Gastrointestinal schwannomas are classified as mesenchymal or neuroectodermal neoplasms. Most common site is stomach followed by rectum. Schwannoma of oesophagus is very rare. It can present with dysphagia and odynophagia. Case Report: A 30-year-old female was presented with progressive dysphagia, mild odynophagia, retrosternal heartburn and vomiting for last six months. On radiological investigations a rounded radio opaque shadow in right paratracheal region was seen. Endoscopy showed ulcerated mucosa that bled on touch. Lumen was narrowed. Endoscopic biopsy showed only mild dysplasia in squamous epithelial lining. Segmental oesophagectomy was done to remove the mass. On gross examination an already cut open segment of oesophagus of about 6 em in length was received. An irregular, lobulated, firm, grey white growth, of 7x5x8.5 em, having smooth external surface was observed towards serosal surface. Cut surface was homogenous white. Histology showed monomorphic spindle shaped cells arranged in fascicular and whorled pattern with nuclear palisading at places. Peri tumoral lymphoid aggregates were also seen.Conclusion: Oesophageal schwannomas are benign tumors having excellent prognosis following surgical resection. A case of oesophageal schwannoma is documented here.
