Cartilaginous choristoma of the tongue—report of two cases and review of literature

Cartilaginous choristoma of the tongue

“…Cartilaginous choristomas in the palate [3], buccal mucosa [4], gingival [5], oral vestibule [6], lower lip [7], and tongue including dorsum [2,8], ventral surface [9], lateral margin [8] are reported. In a review of cartilaginous choristoma, the age at diagnosis ranges widely from 10 to 80 years, with a mean of 47 years.…”

“…Fifty-eight percent of the patients are female, and the mass size ranges from <1 cm to several centimeters [1]. They occur most frequently in the tongue [1,8]; the middle dorsal is the most frequently observed location of cartilaginous choristoma on the tongue [2,8]. Histologically, cartilaginous choristoma is composed of a tumor-like mass of hyaline cartilage surrounded by dense, fibrous connective tissue suggestive of perichondrium, by loose fibrous connective tissue, or occasionally by myxoid tissue suggestive of primitive mesenchyme.…”

Investigation on the occurrence of Hairy Polyp and Choristoma in Oral Cavity: A case study

“…Choristoma was originally reported by Monserrat in 1913 [10]. It is a benign lesion frequently affecting the dorsum of the tongue posterior to the circumvallate papillae and less frequently in other sites of oral cavity including buccal mucosa, soft palate and gingiva [6,9,10]. Choristoma presents as an asymptomatic pedunculated or sessile lump.…”

“…Choristoma is histologically a normal tissue proliferation and it is normally found in ectopic locations [2,6]. It consists of tissues from more than one germ layer.…”

“…Choristoma can be seen frequently in the tongue and less frequently in other areas of the oral cavity. It is usually triggered by a developmental or due to local trauma [6]. Complete surgical excision is the treatment of choice for both hairy polyp and choristoma.…”
