Kimura disease with proliferative squamous metaplasia: an unusual finding and a potential diagnostic pitfall.
Kimura disease is a rare form of chronic inflammatory disorder involving subcutaneous tissue, predominantly in the head and neck region and frequently associated with regional lymphadenopathy and/or salivary gland involvement. We present a case of Kimura disease in a 28-year-old male which showed florid squamous metaplasia in the salivary gland ducts and salivary duct inclusions in the intraparotid nodes besides the usual features of Kimura disease. The squamous metaplasia was extensive enough to pose a diagnostic dilemma. We describe this case to highlight the rare histological finding of florid squamous metaplasia in Kimura disease and its diagnostic implications.
