Symptomatic Schwannoma of the Abdominal Wall: A Case Report

Abstract

Schwannomas are rare benign tumors originating from Schwann cells of the nerve sheath, typically found in peripheral nerves. While they commonly affect extremities, occurrences in parenchymatous organs like the liver are exceedingly rare. Here, we present the case of a 62-year-old man with a symptomatic abdominal wall schwannoma, a unique finding in the medical literature. The patient underwent surgery for a liver hydatid cyst a year prior and subsequently experienced right hypochondrial pains localized at the laparotomy scar. The nodular mass was discovered intraoperatively, prompting surgical excision with enucleation and Lagrot intervention, which resulted in an uneventful postoperative recovery. Histological examination confirmed the diagnosis of a benign schwannoma. This case highlights the importance of considering schwannomas as a rare cause of abdominal pain and emphasizes the favorable prognosis associated with surgical management.
