Description
Abstract
Human kidney sections taken at autopsy were
examined to determine the incidence of metaplasia of the
Bowman's parietal epithelium. Autopsy records were
consulted to determine if there was any correlation between
clinical disease, histopathological changes in organ systems
and metaplasia of Bowman's capsule. The sections
represented both sexes in 9 age groups from 2 to 87 years.
The sections were fixed in neutral formalin, embedded in
paraffin, sectioned at 6 pm, and stained with hematoxylin
and eosin. A total of 129 kidney sections, representing 129
individuals, were evaluated. One hundred renal corpuscles
were counted per section and the parietal layer of Bowman's
capsule was classified as normal (squamous) or metaplastic
(cuboidal). Of the 129 kidneys examined, 69 (53%) had
metaplasia of Bowman's capsule. Of the 87 male kidneys,
51 (59%) exhibited metaplasia of Bowman's capsule. Of
the 42 female kidneys examined, 18 (43%) of the kidneys
had metaplasia of Bowman's capsule. On average, in
kidneys with metaplasia, 4% of the renal corpuscles had
metaplasia of Bowman's parietal layer. The lesion was
present in both sexes in all age groups. The autopsy records
revealed that there was no common clinical condition
associated with the metaplastic lesion, but metaplasia of
Bowman's parietal epithelium was consistently present with
hepatic congestion and/or fatty changes
