# Curious Case of Facial Pain Mimicking Temporomandibular Disorder

## TL;DR

A man's facial pain was initially thought to be a jaw disorder but turned out to be caused by a rare mass in his muscle.

## Contribution

The case highlights the importance of considering rare causes when diagnosing facial pain.

## Key findings

- Initial treatment for temporomandibular disorder failed to relieve the patient's symptoms.
- Imaging revealed a mass in the lateral pterygoid muscle, which was later surgically removed.
- Histopathology confirmed a rare and unexpected diagnosis.

## Abstract

Facial pain is a common but complex complaint, frequently associated with dental issues or temporomandibular disorder (TMD). However, rare aetiologies can complicate conventional diagnoses and treatment approaches. We present a case of a 36-year-old male with persistent jaw pain and restricted mandibular movement, initially managed as a typical TMD case. Conventional treatments yielded no improvement, prompting advanced imaging, which identified an unusual mass within the lateral pterygoid muscle. A surgical excision of the mass was performed, and histopathological examination revealed a rare and unexpected diagnosis. This case highlights the importance of considering uncommon conditions in the differential diagnosis of TMD and facial pain to ensure timely and appropriate therapeutic interventions.
