Tumefactive Fibroinflammatory Lesion: A Diagnostic Dilemma

TFLs are seen more frequently in males between 10 and 74 years of age. The usual site of involvement is the head and neck region, but rarely the extremities may be involved. Coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosi...
