Abstract

Abdominal wall schwannomas are rare neoplasms originating from peripheral nerve sheaths. We present a case report of a 21-year-old patient with a ten-year history of a subcutaneous mass on the left flank of the abdomen. The mass exhibited a hard consistency and was adherent to the deep plane. Palpation elicited pain, and magnetic resonance imaging (MRI) initially suggested a dermoid cyst in intimate contact with the external oblique muscle. The patient underwent wide excision of the mass with a 2 cm margin and subsequent closure of the resulting muscle and aponeurotic defect by direct suturing. Histopathological examination confirmed the diagnosis of a completely excised subcutaneous schwannoma. This case emphasizes the importance of considering schwannomas as a differential diagnosis for abdominal wall masses and highlights the challenges in diagnosing and managing abdominal wall schwannomas. By presenting a comprehensive review of the literature, we aim to contribute to the existing knowledge of this rare entity, facilitating early recognition and appropriate management of abdominal wall schwannomas in clinical practice.

Keywords: Abdominal wall, schwannoma, benign neoplasms, MRI
