Soft Tissue Sarcoma With Tongue Metastasis: A Case Report and Literature Review.

Soft tissue sarcomas are rare malignant tumors that develop from mesenchymal cells. Metastasis is predominantly hematologic, with the lungs being the most common site. Metastasis to the oral cavity is a rare occurrence. The most common primary tumors to metastasize to the oral cavity are adenocarcinoma of the lung, breast, and kidney. This report describes a case of a 41-year-old man who was diagnosed with myxofibrosarcoma of the lower extremity and underwent neoadjuvant chemoradiation followed by surgical resection. Two years later, he presented with metastasis to the tongue and lungs. The literature on tongue metastasis of soft tissue sarcoma is reviewed and discussed. Surgeons providing care to patients with a soft tissue sarcoma should maintain a strong clinical suspicion for distant metastases in patients with this type of tumor.
