Summary
Lung cancer can cause rare referred facial pain, often in the trigeminal nerve area. Early diagnosis and treatment of the lung tumor can significantly improve this persistent pain.
Area of Science:
- Neurology
- Oncology
Background:
- Unilateral facial pain, particularly in the trigeminal distribution, can be an unusual symptom of superior pulmonary lobe cancers.
- Referred facial pain is a rare clinical presentation, often linked to advanced lung malignancies.
Observation:
- A 65-year-old male smoker presented with persistent otalgia and left-sided mandibular pain unresponsive to analgesics.
- Initial investigations for common causes of facial pain were inconclusive.
- Dyspnea preceded the diagnosis of left lung cancer.
Findings:
- The patient's facial pain improved following radiotherapy and chemotherapy for lung cancer.
- Referred facial pain, potentially due to tenth cranial nerve invasion by upper lobe tumors, can manifest as otalgia and V3 distribution pain.
- Diagnosis of the underlying lung cancer can be delayed by months to years after pain onset.
Implications:
- This case highlights the importance of considering referred pain from lung cancer in patients with unexplained trigeminal facial pain.
- Prompt diagnosis and treatment of the primary lung tumor are crucial for managing cancer-related facial pain.
- Awareness of this rare presentation can aid clinicians in earlier diagnosis and intervention.

01:44Nociception
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain. Thus, pain helps the...
01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:14Cranial Nerves: Types Part I
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

01:22Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.

01:20Pain
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...
