              Abstract 
 
A rare report of papillary adenoma in the trachea of a free-ranging wild boar 
has been reported in the article. In the case, except for the growth in the 
trachea, there were no other significant lesions observed in the carcass. 
Grossly, the adenoma was granular and microscopically, it comprised finger like 
projections with the features of hyperplastic glandular epithelium and increased 
mitotic figures. This case is first of its kind and also its occurrence is 
negligible in other animals. Few cases have been reported in the humans with the 
history of excessive smoking. Although, adenomas of other organs are common in 
pigs. However, authors are unaware of previous reports of such case in the 
animals.
