To the question of pathological and anatomical changes in the kidneys with their syphilitic lesion

Despite the fact that an extensive literature is devoted to kidney syphilis, this question still cannot be considered finally resolved. The kidneys can be exposed to the action of syphilitic infection in any period of syphilis, but specific morphological changes in them are found only in the gummy period of the disease. Gumma diseases observed in this period are among the very rare finds during the section. When looking through the extensive literature, we did not come across definite statistical indications of the frequency of kidney damage by the gummy process and found only random information about the amount of renal gummy syphilis. So in Wagner (1881) on 9000 sections of the kidney gum were found in 3 cases; Spiess (1877) had 7 cases of gummy interstitial nephritis in 220 autopsies of syphilitics. Lancereaux (1866) noted one case of kidney gum in 24 syphilitic sections. The rarity of gummy kidney damage can be judged to a certain extent because among the vast museum of the Pathological and Anatomical Institute of Kazan University for a long period of its existence there has not been a single case of such a change in the kidneys.
