Oviduct - Atrophy
Oviduct atrophy is an uncommon lesion and would be expected to occur in association with atrophy of the ovary and uterus or with inflammation. Features of oviduct atrophy include a decrease in the cross-sectional diameter of the oviduct, decreased thickness of the smooth muscle wall, decreased epithelial height, and flattened fimbria and/or mucosal folds ( Figure 1 and Figure 2 ). This lesion must be differentiated from hypoplasia.
recommendation:Oviduct - Atrophy should be diagnosed and graded whenever present.
