2025年1月10日 · This rare benign peripheral nerve tumor arises from perineurial cells, a type of cell that surrounds the peripheral nerve sheath. A perineurioma can form within a nerve, called an intraneural perineurioma.

2024年7月19日 · Peripheral nerve tumors can occur anywhere in the body. Most of them are benign, meaning they're not cancerous. But they can lead to pain, nerve damage and loss of function in the affected area. Treatment usually involves surgery to remove the tumor.

2024年7月31日 · Malignant peripheral nerve sheath tumors (MPNSTs) affect nerves that manage your muscles and sense of touch. In MPNST, cells that make up nerves’ protective shield become cancerous and multiply to develop tumors. It’s a very rare cancer that grows very quickly. The most common treatment is surgery to remove the tumors, but they often come back.

Hybrid nerve sheath tumor Benign Very rare The most common site is the fingers; Rare cases of cranial nerves involvement; Malignant peripheral nerve sheath tumour (MPNST) (epithelioid and perineural subtypes) Malignant 2–10% of soft tissue sarcomas. Epithelioid MPNST is particularly rare (~5% of all MPNST) Extremities, trunk, head, and neck area

There are several types of peripheral nerve sheath tumors, but most are either schwannomas or neurofibromas. These tumors are usually benign and grow slowly. In some cases, however, they can cause debilitating pain, sensory issues, and weakness or paralysis of a particular muscle group if left untreated.
