Solitary Circumscribed Neuroma
A benign, well-circumscribed intraneural proliferation of Schwann cells and axons.
Not rare but probably underdiagnosed.
Equal gender distribution.
There is a strong predilection for the skin of the central face and the mucocutaneous junction, but the oral mucosa can also be affected (Koutlas, Scheithauer, 2010, Leblebici et al., 2019). Acral skin and penis are rare locations.
Simple excision is curative.
This tumor is entirely benign. There is no association with NF1 or MEN2b.
Small superficial nodule.
