Sessile is a pathological term which is used for lesions that are attached by their base, that is they lack a stalk i.e. are not pedunculated. It is most commonly used for intraluminal polyps in the GI tract.

History and etymology

Sessile is derived from the Latin word "sessilis" which means sitting, itself from the past participle of the Latin verb "sedere", meaning to sit. It is first used in botany in 1753 and in zoology in 1777 ².
