Myxoinflammatory fibroblastic sarcoma of the finger: a case report.

Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare low-grade sarcoma that occurs in the subcutaneous tissue of the distal extremities. MIFS was first described in 1998. There are many differential diagnoses, and it can often be mistaken for several different inflammatory and neoplastic processes, which may require different treatment. There is much literature published for pathologists, but only a few reports for orthopedic surgeons to treat such tumors. It is significant and important to report this additional case of MIFS that occurred in the right ring finger and to acknowledge the very existence of the tumor as a differential diagnosis to be made by hand surgeons. Hand surgeons need to be mindful of MIFS, its nature, and the appropriate treatment necessary for this unique tumor.
