Teaching points

NELL1-associated membranous glomerulopathy frequently exhibits a segmental or segmental to global distribution of subepithelial deposits.

Membranous glomerulopathy may occur in the setting of hematopoietic stem cell transplantation where it represents a form of graft-versus-host disease and is usually PLA2R-negative.

A subset of membranous glomerulopathy in patients with graft-versus-host disease shows a segmental distribution of deposits, tubular basement membrane deposits, and NELL1 positivity.

NELL1, neural epidermal growth factor–like 1; PLA2R, phospholipase A2 receptor.
