Introduction: Schwannomas are rare, usually benign, tumors that arise from the myelin sheath of nerves. Only 1% of schwannomas are localized in the retroperitoneal space. Preoperative diagnosis can be difficult as symptoms are non-specific.
Case Report: We present the case of a 32-year-old woman who presented with suspected appendicitis. A lateral uterine mass was discovered on imagery, and was surgically resected. Schwanomma was diagnosed on histopathological and immunohistochemical analysis with intense staining of the S100 protein. The resected mass had healthy margins. The patient reported neurological disorders three weeks after surgery which improved with physiotherapy.
Conclusion: This case illustrates the difficulties of diagnosing schwannoma and supports the relevance of a surgical approach. Complete surgical resection can prevent recurrence or worsening, and is recommended in despite the risk of morbidity.
