Bibek Kattel, Akunchan Shrestha, Siddhartha Rai, Niroj Khanal, Shashi Keshwar, Mehul Rajesh Jaisani
TL;DR
A rare case where a neurilemmoma was initially mistaken for a dermoid cyst is described, highlighting diagnostic challenges in the submandibular region.
Contribution
This paper presents a unique clinical case of neurilemmoma masquerading as a dermoid cyst, emphasizing diagnostic pitfalls in this anatomical region.
Findings
The lesion was initially diagnosed as a dermoid cyst via ultrasonography but confirmed as neurilemmoma through histopathology.
The mass was encapsulated and successfully excised without neurological deficits.
The case underscores the importance of histopathological confirmation for accurate diagnosis in this region.
Abstract
Neurilemmomas in the submental and submandibular region represent a diagnostic challenge, often mimicking more common superficial cysts. This is a case of neurilemmoma of the marginal mandibular branch of the facial nerve, initially diagnosed as a dermoid cyst via ultrasonography in a 65‐year‐old male with an 18‐month history of a painless 1.5‐cm mass. Histopathological examination of the excised lesion confirmed neurilemmoma. The mass was encapsulated and easily detached from the surrounding tissue; thus, successful excision without postoperative neurological deficits was ensured.
