A Case of Inflammatory Fibrosarcoma in the Maxillary Sinus / 대한이비인후과학회지

ABSTRACT

Inflammatory fibrosarcoma is an uncommon disease that results from accumulation of inflammatory cells and relatively high recurrences rate in childhood. It has been reported that it most often occurs in lungs and sometimes in gastrointestinal tract, and head and neck. Head and neck lesion is from nasal cavity and paranasal sinus. Early symptoms are nonspecific and early diagnosis is difficult. Most cases are therefore diagnosed at the late stage. Invasion of inflammatory fibrosarcoma to orbital wall, cribriform plate and skull base is also common. We present a 75-year-old woman with inflammatory fibrosarcoma, which occurred in the right maxillary sinus and nasal cavity.
