Electron microscopy findings at the first biopsy. (A) Numerous paramesangial electron-dense deposits (EDDs) of various sizes and segmental widening of subendothelial areas with electron-lucent materials were evident (arrows). (B) Giant globular materials widened the subendothelial space remarkably and compressed endothelial cells to the opposite side (arrows). Paramesangial and subendothelial EDDs were also seen in the lower and upper parts of the photograph, respectively.
