Heterotopia of the tonsil

Abstract

The histopathological finding of heterotopias or choristoma is rare. This paper describes two patients who presented with chronic recurrent tonsillitis and underwent tonsillectomy. Histological examination revealed heterotopic cartilage in the tonsil of one patient and bone in that otthe other.

Cartilaginous choristoma of the nasopharynx

“…Bhargava et al (1996) report that choristomas of the head and neck are rare lesions and describe a case study of a cartilaginous choristoma associated with the tonsil. We report findings from a patient who had a symptomatic cartilaginous mass that masqueraded as adenoidal hypertrophy and attribute its etiology to mesodermal origin due to notochordal influence.…”

Cartilaginous Choristoma in Tonsil : A Rare entity

“…Heterotopic tissue as hamartoma or choristoma is another interesting findings [3]. Cartilaginous choristoma was first described by Berry in 1890 [1,4]. The age group ranges widely from 10 to 80 years.…”

“…Choristoma is an island of normal tissue in an abnormal location Cartilaginous choristoma was first described by Berry in 1890 [1]. The age of diagnosis varies greatly from 10 to 80 years.…”

Chronic Hyperplastic Polypoid Tonsillitis

“…Ectopic salivary tissue, 4 meningeal tissue, 5,6 infectious like actinomycosis, heterotopic glial tissue, 7 choristoma with osteocartilaginous, 8 dermoid have been reported in tissues slide.…”
