necrotizing sarcoid granulomatosis

Monday 7 March 2005

Definition: Necrotizing sarcoid granulomatosis (NSG) is a disorder of unknown etiology, rarely described in childhood, belonging to the heterogeneous group of the pulmonary angiitis and granulomatosis.

One of the characteristics of NSG is to have typically a benign clinical course with minimal treatment with systemic steroids or even with no therapy at all.

Necrotizing sarcoid granulomatosis (NSG) is characterized by pulmonary nodular infiltrates, a typical histology, and a benign clinical course. The etiology and pathogenesis of the disease are still unknown.
