title: Lymphomatoid granulomatosis in a 4-year-old boy.
abstract: Lymphomatoid granulomatosis is a necrotizing angiocentric and angiodestructive infiltrative process involving primarily the lung, skin, central nervous system, and kidney. The incidence is highest in middle-aged men and is rare in children. We report a case of lymphomatoid granulomatosis involving both skin and lung in a 4-year-old boy. The disease progressed to peripheral T-cell lymphoma, which was unusual in light of recent evidence suggesting a B-cell origin in the majority of cases.
