Myxoinflammatory fibroblastic sarcoma of the neck.

Background: Myxoinflammatory fibroblastic sarcoma (MIFS), also named inflammatory myxohyaline tumor of distal extremities with virocyte or Reed-Sternberg cells, is a rare tumor typically presenting as a painless mass in the extremities.

Patients: We present an unusual case of MIFS presenting as a subcutaneous neck mass. This is the first reported case of MIFS presenting in the neck.

Results: Therefore, this lesion must be considered in the differential diagnosis for painless subcutaneous masses presenting not only in the distal extremities, but also in the neck.

Conclusion: MIFS has only recently been recognized. The differential diagnosis for MIFS is broad, and it can often be mistaken for several different inflammatory and neoplastic processes, which may require different treatment.
