Kimura's disease: a rare cause of facial mass in a caucasian male patient.

Kimura's disease is an uncommon inflammatory disorder of unclear aetiology, mainly affecting young Asian descent males among their second and fourth decades of life. The disease typically emerges as a long-standing and painless subcutaneous mass lesion in the head and neck region, frequently associated with swelling of major salivary glands, particularly the parotid gland, and regional lymphadenopathy. Peripheral eosinophilia and high serum immunoglobulin E are also characteristic findings. We report a case and describe the imaging and pathological features of the disease in a 19-year-old Caucasian male, with review of the literature.
