Description	preputial gland papilloma
Age at Necropsy	800 days
Notes	This is the preputial gland from an 800 day old male PWD/PhJ mouse. Note the duct is massively ectatic, not an unusual finding for an old male mouse. However, the dilated duct is effaced by numerous papillary projections into the lumen of proliferating epithelium on thin fibrovascular stalks. This is a stratified squamous papilloma of the preputial gland.
