[Fibroblastic and myofibroblastic tumors of the head and neck].

Fibroblastic and myofibroblastic tumors of the head and neck are numerous and may develop either in adults or in childhood. They can be benign and nonrecurring, benign but locally recurring, of low-grade of malignancy or fully malignant. The diagnosis and treatment of these lesions can be difficult. This review focuses on several (myo)fibroblastic lesions of the head and neck, including nodular fasciitis and related neoplasms, hemangiopericytoma-like tumor (glomangiopericytoma) of sinonasal passages, nasopharyngeal angiofibroma, desmoid fibromatosis, Gardner-associated fibroma, extrapleural solitary fibrous tumor, inflammatory myofibroblastic tumor, low-grade myofibroblastic sarcoma, and adult-type fibrosarcoma.
