formation of a crescent-shaped (semi-lunar) glomerular lesion corresponding to extracapillary proliferation of Bowman's capsular epithelium and acquiring a fibroblast-like spindled morphology, possibly stimulated by release of fibrinogen from a ruptured glomerular basement membrane; epithelial crescents occur in aggressive forms of glomerulonephritis, may be accompanied by collagen and fibrin deposition and/or monocyte and macrophage proliferation, may protrude into Bowman's space, and ultimately compress and destroy the glomerular tuft
