From: Glomerular tip adhesions predict the progression of IgA nephropathy
Glomerular tip prolapse and glomerular tip adhesions accompanied by segmental sclerosis. A and B. Glomerular tip prolapse, which is distinct from glomerular tip adhesions, in patients excluded from the present study. The dotted line indicates the border between the glomerulus and the proximal tubules. The glomerular component prolapses into the tubular area (PAMS stain, 200×). C and D. In this glomerulus with a glomerular tip adhesion, the upper portion shows evidence of segmental sclerosis (C: PAMS stain, 200×; D: AZAN stain, 200×).
