Background : Myxofibrosarcomas often occur subcutaneously in the extremities. Outbreaks in the head and neck area are extremely rare. We report herein on a case of myxofibrosarcoma clinically suspected to be a submandibular gland tumor.
Case : A male in his 50 s was suspected as having a left submandibular gland tumor. He was referred to our Department of Otolaryngology. The tumor was elastic and firm on palpation. On the fine needle aspiration (FNA) cytologic findings, tumor cells were spindle sharped/fusiform or having ovoid nuclei with a myxoid matrix against a hemorrhagic background. Tumor cells exhibited marked nuclear pleomorphism and fine granular chromatin. Based on the cytologic findings, the tumor was tentatively identified as a probable myxofibrosarcoma.
Conclusion : Mucus fibrosarcoma can be diagnosed from the findings of the mucus and atypical spindle cells. Myxofibrosarcoma can be diagnosed from cytologic findings of the myxoid matrix and atypical pleomorphic spindle cells.
