A Suspected Metastatic Liposarcoma of the Inferior Alveolar Nerve Canal: A Case Report and Literature Review

 Liposarcoma is the most common soft tissue sarcoma, but it is relatively scarce in the head and neck. The metastatic liposarcoma is more infrequent than the primary one.

 Here is presented a suspected case of metastatic liposarcoma in the inferior alveolar nerve canal in a 40-year-old female patient with a chief complaint of the chin and lower lip numbness and medical history of liposarcoma in the thigh. The present study was a case report for metastatic liposarcoma in the head and neck regions, according to the English language literature found in PubMed and Google Scholar. The search was performed using the keywords "Metastatic Liposarcoma" and "Head" and "Neck".

 According to the findings, the reported case may be the first case of the metastasis of liposarcoma in the inferior alveolar nerve canal. Ominous signs, such as numbness, should be considered in patients with a history of cancer, due to their warning for metastasis or recurrence of the tumor.
