Schwannoma is a solitary, slow growing, benign tumour of the peripheral nerve sheath, and it is most common locations are the head, neck, the flexor surfaces of the extremities, retroperitoneal and posterior mediastinium. External female genital organs are the least common location site of the schwannoma. Only a few cases of vulvar schwannoma have been reported.We report 65 year- old woman presented with a left vulvar swelling, which had been present for several years. The tumor size is 15x12 cm and slowly increased but it prevent patient activities such as walking and sitting. The tumor was resected for treatment and the histological examination confirmed to be a vulvar schwannoma. In our best knowledge, vulvar schwannoma in this case is the largest size in the literature.

- The case report discusses a 56-year-old woman with a complex medical history who presented symptoms like a widespread rash, fever, and body aches, prompting further investigation.

Objective: To describe the clinical and sonographic characteristics of benign, retroperitoneal, pelvic peripheral-nerve-sheath tumors (PNSTs).
Methods: This was a retrospective study of patients with a benign, retroperitoneal, pelvic PNST who had undergone preoperative ultrasound examination at a single gynecologic oncology center between 1 January 2018 and 31 August 2022. All ultrasound images, videoclips and final histological specimens of benign PNSTs were reviewed side-by-side in order to: describe the ultrasound appearance of the tumors, using the terminology of the International Ovarian Tumor Analysis (IOTA), Morphological Uterus Sonographic Assessment (MUSA) and Vulvar International Tumor Analysis (VITA) groups, following a predefined ultrasound assessment form; describe their origin in relation to nerves and pelvic anatomy; and assess the association between their ultrasound features and histotopography.
