Trismus and trigeminal neuralgia in one patient with colon cancer.
ABSTRACT A 64-year-old man got trismus and trigeminal neuralgia under the diagnosis of colon cancer with mandibular metastasis after emergency appendectomy and elective hemicolectomy. The patient chose to forgo further surgery and was given only palliative chemotherapy and radiotherapy. He died six months after diagnosis. Metastatic tumors to the oral cavity are relatively uncommon. They are found most commonly in the mandible, and 70% of cases are adenocarcinoma-most commonly from breast and lung, followed by adrenals, kidneys, prostate, thyroid and colon. Mandibular mass is usually the first sign, then soft-tissue swelling, pain and paresthesias. Tissue proof is needed to confirm the diagnosis. The treatment depends on the nature of the primary, the degree of dissemination and the precise location. However, the prognosis is grim, with the mean survival after diagnosis being only about 6-7 months.

ABSTRACT: Metastatic lesions to the mandible are rare, comprising less than 1% of all malignancies. A 75-year-old gentleman presented to ENT outpatient with a 3-week history of numbness over his lower lip on the right side followed by a rapidly growing swelling in his right mandibular region. The patient was diagnosed with an obstructing sigmoid tumour with metastasis to the liver and retroperitoneal adenopathy, 5 months ago. A colonic stent was inserted for the sigmoid tumour and patient was undergoing palliative chemotherapy. CT scan of the mandibular region showed mass lesion invading the ascending ramus of mandible and involving the right inferior alveolar nerve. Trucut biopsy confirmed metastatic adenocarcinoma.Case Reports 04/2011; 2011. DOI:10.1136/bcr.01.2011.3682

ABSTRACT: Trigeminal neuralgia (TN) is a condition characterized by brief electric shock-like pains in the topography of the trigeminal nerve. The most common cause of this disorder is the compression of the trigeminal nerve root by tortuous or aberrant vessels. In this report, we describe a patient who presented due to paroxysmal and excruciating facial pain that was found to be secondary to pancreatic cancer.Headache The Journal of Head and Face Pain 09/2012; 53(1).
