[Recurrent tumor growth in the right maxilla--a rare case of an inflammatory myofibroblastic tumor].

28 year old male with inflammatory myofibroblastic tumor in the right maxilla undergoes multiple surgeries for the removal of recurrent tumors over a period of 4 years and is without symptoms of recurrences today. Cells cultured from the tumor show stem cell properties that could contribute to the recurrent tumor growth. It is important to do a close follow up on patients with these traits and further recurrences cannot be excluded even though surgical edges are free of tumor growth.
