Ancient schwannomas are a rare variation of schwannomas, with the distinction being based on histopathological examination of the excised specimen. On histopathological examination, ancient schwannomas exhibit degenerative changes such as calcification, hyalinization, and cystic necrosis, along with S100 positivity. Complete surgical excision is the mainstay treatment for ancient schwannomas and carries a favorable prognosis. Recurrence is the most common complication, often arising from incomplete surgical excision. Herein, we present a case of a 41-year-old male who presented to our center as a case of a retroperitoneal mass for further investigations and diagnostic workup. Imaging showed a retroperitoneal mass in the right iliac fossa. We proceeded with ultrasound guided needle biopsy, and examination of the specimen confirmed the diagnosis of ancient schwannoma. Subsequently, the patient underwent surgery, and complete surgical excision was achieved. On follow-up 3-months later, the patient is doing well, and no signs of recurrence were found.

Schwannoma is a rare mass that is benign. It develops from the Schwann cells found in the peripheral nerves. Schwannomas consists of spindle cells exhibiting two unique histological patterns, which may be combined: Antoni type A and type B.

Introduction: Schwannomas are benign solitary, slow-growing, encapsulated, asymptomatic tumors arising from Schwann's sheath of nervous fibers.
Objectives: The current paper presents all the cases diagnosed with different types of schwannomas in the head and neck region between January 2009 and December 2023 in the Western part of Romania. In this period, ten cases of schwannoma were identified.

Key Clinical Message: Benign ancient retroperitoneal schwannomas (BARS) exhibit abdominal masses and flank pain to incidental findings at more advanced stages. Histopathological and immunohistochemical analysis is essential for confirmation of benign nature. Our patient was misdiagnosed as ureteric colic, highlighting the need to consider BARS in differential diagnosis to prevent complications like hydronephrosis.
