comment:

Clitoral gland - Infiltration, cellular may be a spontaneous age-related change in rats and mice but can also be a test-article-related effect. It is characterized by the presence of infiltrating cells (e.g., mononuclear cells, neutrophils, mast cells) within the tissue but with no other evidence of inflammation, such as tissue damage, necrosis, etiologic agents, hemorrhage, congestion, or edema ( Figure 1image opens in a pop-up window , Figure 2image opens in a pop-up window , Figure 3image opens in a pop-up window and Figure 4image opens in a pop-up window ). Infiltration cellular must be differentiated from inflammation, in which there is other evidence of inflammation as listed above.

recommendation:

Clitoral gland - Infiltration cellular should be diagnosed and assigned a severity grade. The type of infiltrating cell should be specified as a modifier in the diagnosis.
