Zymbal’s Gland, Duct - Cyst
comment:Zymbal's gland duct cysts ( Figure 1 , Figure 2 , Figure 3 , and Figure 4 ) are prominently distensions of the Zymbal's gland duct that are lined by either attenuated squamous or glandular epithelium or by flattened stratified squamous epithelium. The former are typically filled with sebum, while the latter typically contain sloughed keratin lamellae. Zymbal's gland cysts are uncommon, but this may reflect the fact that this tissue is not usually sampled in routine toxicity studies.
recommendation:Zymbal's gland duct cysts should be diagnosed whenever present but should not be graded.
