- Walthard cell rest
Walthard cell rests; sometimes called Walthard cell nests, are an accumulation of
epithelialcells most commonly found in the peritoneumof the Fallopian tubes, but also seen in the mesovarium, mesosalpinxand ovarian hilus. They appear as white/yellow cysts or nodules that can reach a size of 2 milimeters. They are named after Swiss gynecologistMax Walthard (1867-1933), who provided a comprehensive description of them in 1903.
It has been suggested that these cell rests are the histogenetic origins of
Brenner tumors. Due to the histological similitude of the epitheliumof Walthard cell rests and Brenner tumors to the urotheliumof the lower urinary tract, it has been proposed that Brenner tumors and Walthard cell rests signify urothelial differentiation within the female genital tract.
