Numb chin syndrome is a sensory neuropathy characterized by numbness involving the distribution of the mental nerve that could be an uncommon manifestation of metastatic malignancy. Bony metastases are common in patients with advanced prostate carcinoma and involving preferentially vertebrae, sternum, pelvic bones, ribs and femurs. We report a case in an 82-year-old man presenting a history of mental neuropathy as the isolated presenting symptom of a widespread metastatic prostate cancer Numb chin syndrome was describe in some reviews as a late component of a previously diagnosed disease but this report underline the importance of this neuropathy as the isolated presenting symptom of a widespread metastatic prostate cancer. This event is very rare and enumerates four cases in the world literature.

Numb chin syndrome (NCS) is a sensory neuropathy presenting with numbness of the chin in the distribution of the mental nerve and the branches of the mandibular division of the trigeminal nerve. Though it can be caused by a benign process, NCS should be regarded as being due to malignancy until proven otherwise. Among the malignancies that cause NCS the most common are breast cancer, prostate cancer, and lymphoreticular malignancy. In squamous cell carcinoma (SCC) of the esophagus, spread to the mandible is a rare and often late event. An often overlooked clinical sign in mandibular metastases is hypoesthesia or paresthesia over the peripheral distribution of the inferior alveolar nerve/mental nerve; this sign has been referred to in the literature as NCS or numb lip syndrome or mental nerve neuropathy. Rarely, this may be the first presentation of a disseminated malignancy. Prognosis is usually poor. The discovery of this symptom should alert the clinician to the possibility of disseminated disease. In this article we report a rare case of metastatic SCC of the esophagus in a 40-year-old male patient who presented with NCS. We also review the mechanism, causes, and evaluation of NCS.

Numb chin syndrome (NCS) is a rare cranial neuropathy characterized by facial numbness in the distribution of the mental branch of the inferior alveolar nerve. Although commonly associated with local trauma, NCS can indicate an underlying neoplastic condition. Although NCS is most commonly associated with nonmalignant disease states, it may be the presenting symptom of a systemic malignancy, and its prompt recognition is essential for proper management. NCS is associated with a variety of neoplastic conditions but is most commonly seen with lymphoproliferative conditions, breast cancer and prostate cancer. When confronted with a possible diagnosis of NCS, clinical evaluation should include evaluation for occult malignancy or relapse of any known previous cancer. In this study, a case of a patient with NCS in the context of a new diagnosis of acute myeloid leukemia with differentiation with a t(8;21) translocation is presented and the literature regarding the multiple etiologies and significance of NCS reviewed.

Numb chin syndrome (NCS) is defined as reduced or absent sensation in an area of the chin and lower lip within the distribution of the mental or inferior alveolar nerves. The causes of NCS may be neoplastic, traumatic, dental, toxic, drug-induced, inflammatory, autoimmune or infectious. NCS may be the preliminary symptom of malignancy or recurrence/metastasis in patients with cancer. Therefore, the occurrence of NCS warrants careful examination and monitoring of such patients. This article presents two cases of NCS reported in a patient with prostate cancer and in a patient with Burkitt lymphoma/leukaemia.
