Chin Numbness as a Presenting Symptom of Malignancy.

Numb Chin Syndrome (NCS) is a sensory neuropathy that was first described in the early 1800s. It has various etiologies, most commonly benign local pathology. However, NCS has been documented as the primary presenting symptom of systemic malignancy, most commonly breast cancer.1 This is the case of a young male who presented to the emergency department with complaints of a numb chin and was ultimately found to have invasive neoplastic lesions in the right tonsillar and mandibular regions of the face arising from metastatic large B-cell lymphoma.
