Kimura’s Disease: A case report
Shilpa.C.Patel, Vishal.R. Dave
Abstract
Kimura’s disease is a rare inflammatory disorder of unknown cause, primarily seen in young
Asian males. The disease is characterized by a triad of painless subcutaneous masses in head and neck
region, blood and tissue eosinophilia and moderately elevated serum immunoglobulin E levels. Here, we
present a case report of this rare entity of unusual age presentation with classical histopathogical features.
