AI Article Synopsis
- Plexiform schwannoma is a rare benign tumor that usually appears in young adults, affecting areas like the trunk, head, neck, and extremities, and is typically under 2 cm in size.
- * The tumor is characterized by a plexiform growth pattern and multinodularity, which can make it look similar to plexiform neurofibroma, a tumor with higher risks of recurrence and malignancy.
- * A case study discusses a 14-year-old girl with an 11 cm mass on her foot that was diagnosed as plexiform schwannoma through histological evaluation and strong S-100 immunostaining.
Article Abstract
Plexiform schwannoma is a rare benign nerve sheath tumor usually located in trunk, head, neck, upper extremities and occasionally in lower extremities. It is usually less than 2 cm in size and generally affects young adults. The tumour is composed of schwann cells and exhibit a plexiform growth pattern both in gross or histologic examination and is frequently accompanied by multinodularity causing serpentine distortion. Plexiform neurofibroma commonly mimics plexiform schwannoma and it is important to differentiate between them, as recurrence and malignant potential are more common with plexiform neurofibroma. We present the case of a 14-year-old female with history of a nodular soft tissue mass over his right foot measuring 11 cm in length. A Doppler scan of the foot was suggestive of thrombosed superficial vein in right foot. The histological evaluation of the mass revealed Plexiform schwannoma. S-100 immunostaining is diffuse and strong confirming the diagnosis of Plexiform schwannoma.

Article Synopsis
- - Plexiform schwannomas are a rare type of tumor, making up only 5% of all schwannomas, and instances in the thyroid are even rarer.
- - A 32-year-old male was found to have a large, asymptomatic mass in his thyroid gland, which was later diagnosed as a plexiform schwannoma after surgery.
- - This case marks the first reported occurrence of a plexiform schwannoma in the thyroid in English literature, underscoring the need for comprehensive evaluation in diagnosing unusual thyroid masses.

Introduction And Importance: Schwannomas are benign tumors that arise from Schwann cells commonly located in peripheral nerves. Depending on the size and location of sciatic nerve Schwannoma clinical manifestations can either varies from symptoms simulating radiculopathies such as positive Lasegue sign on the affected side, gait weakness and paresthesia or just present with pain and an associated palpable mass.
Case Presentation: The authors present a case of a 34-year-old female patient suffering from pain, gait weakness, and a palpable mass since many months.
