Aim and background: To demonstrate the clinical findings and management of a retroperitoneal Schwannoma, which presented as a gynecological mass. Nerve sheath tumors are benign tumors affecting the cranial and peripheral nerves. Schwannoma refers to tumors arising from the Schwann cells of neurons. Case description: A 56-year-old female presented to us with vague lower abdominal pain since 3 months. It was initially diagnosed as a inclusion cyst. Intraoperatively diagnosed with retroperitoneal benign looking mass, which turned out to be a schwannoma. We present a case of leftsided retroperitoneal schwannoma which masqueraded as a gynecological mass and operated by laparoscopy. Conclusion: Schwannomas are benign, encapsulated, slow-growing nerve sheath tumors. Rarely seen in the pelvis and retroperitoneum. Laparoscopy aids in better visualization with more accurate surgical removal of these masses and can be considered the treatment of choice for these tumors. Clinical significance: Often asymptomatic and may go unnoticed, but when presenting with symptoms or when discovered incidentally on scans for other reasons, they are mistaken for gynecological or urological masses and are more often presented to gynecologist/urologist.
