Palisaded encapsulated neuroma (PEN) is a distinctive benign neural tumor, which usually presents as a solitary skin-colored papule or a nodule. It is a benign lesion and may clinically mimic a cutaneous neurofibroma, melanocytic nevi, or cutaneous schwannoma.
What is a solitary circumscribed neuroma?
Background: The solitary circumscribed neuroma or “Palisaded Encapsulated Neuroma” is an infrequent benign tumor of the skin of adults, often localised on the face, around the orifices. The involvement of the oral mucosa or of the vermilion border of the lips is rare.
What is a skin neuroma?
Palisaded encapsulated neuroma of the skin, also referred to as solitary circumscribed neuroma, is a benign cutaneous tumor of the skin that clinically presents as a firm, flesh-colored, dome-shaped papule with loss of overlying skin markings [1].
What is a neuroma on the tongue?
A benign tumor of nerve tissue commonly found on the tongue, lips, or in the gastrointestinal tract. Mucosal neuromas are a characteristic feature of multiple endocrine neoplasia type 2B (also known as MEN3), which is a hereditary syndrome associated with the development of medullary thyroid cancer.

Are neuromas encapsulated?
A palisaded encapsulated neuroma is a benign cutaneous neoplasm that most commonly presents as a painless, dome-shaped, flesh-colored nodule or papule. The lesions typically appear on the face; however, albeit rarely, they may also develop on the extremities, trunk, or genital region.
Can you have a neuroma in your mouth?
A traumatic neuroma is a type of neuroma which results from trauma to a nerve, usually during a surgical procedure. The most common oral locations are on the tongue and near the mental foramen of the mouth. They are relatively rare on the head and neck.
What is Neurilemmoma?
A neurilemmoma, also known as schwannoma, neurolemmoma, and peripheral fibroblastoma, is a benign, encapsulated neoplasm derived from Schwann cells. Along with neurofibroma, schwannoma constitutes one of the two most common benign peripheral nerve sheath tumors.
Is neuroma encapsulated?
Palisaded encapsulated neuroma (PEN) is a rare, benign cutaneous condition characterized by small, firm, non-pigmented nodules or papules. They typically occur as a solitary (single) lesion near the mucocutaneous junction of the skin of the face, although they can occur elsewhere on the body.
Is a neuroma hard?
Neuroma pain can be burning, sharp, tingling sensation, or numbness. On examination, a well defined hard lump is usually palpable, which can be adherent to nearby structures. On pressure, patients can experience a sensation similar to electric shock.
How do you get rid of traumatic neuroma?
Treatment for the traumatic neuroma consists of surgical excision, which should include a small portion of the proximal nerve bundle. Most such lesions do not recur, although some examples may return or be associated with persistent pain at the site.
