A Case of an Incidentally Removed Lingual Osseous Choristoma

Abstract

Lingual osseous choristoma is a rare benign tumor consisting of normal matured bone tissue. It was first reported in 1913, and less than 100 cases of lingual osseous choristomas, mainly in their twenties and thirties, have been reported in the English literature until now. Here, we report an additional case of lingual osseous choristoma, in an elderly patient, that was incidentally removed by coughing and cured without additional interventions. An 89-year-old male patient was referred to our department for an evaluation of chronic cough. When we examined his oral cavity and pharynx, he expectorated a 10 -mm mass which was histologically diagnosed as an osseous choristoma. We confirmed the well-defined, rounded, high-density mass with a tiny pedicle on the base of the tongue in previous cervical spine CT images. No signs of recurrence were found during the 15-month follow-up examination. Our case serves as a reminder of this rare entity in the diagnosis of tongue masses of the elderly.

Tongue Osseous Choristoma in an 11-Year-Old Female: A Case Report and Literature Review Focusing on Pediatric Cases

“…Thus, we focused on patients below the age of 13 years with osseous choristoma in our literature search. To our knowledge, in the literature, 62 cases have been described on patients above the age of 13 years ( Table 1 ) [ 1 , 3 , 6 , 8 – 45 ]. On the other hand, 16 cases have been described in children below the age of 13 years ( Table 2 ) [ 1 , 2 , 4 , 6 , 31 , 44 , 46 – 55 ].…”

“…Regarding the correlation in pediatric cases, we could not conclude from only 5 cases (29.4%). To resolve this discordance, it is necessary to recruit more cases [ 45 ]. The follow-up period ranged from one year to three years.…”

“…Given that no attending surgeons considered the possibility of an osseous choristoma, we did not conduct any imaging examination in this case. An earlier study reported computed tomography (CT) images are useful for the radiological diagnosis of lingual osseous choristoma [ 45 ]. Also, Yoshimura et al reported the usefulness of not only radiographic examination for the surgical specimen.…”

“…Additionally, they proposed developing a miniaturized, flexible dermoscopy that enabled the detailed examination of the whole oral cavity [ 54 ]. However, it is difficult for children to follow instructions when undergoing a CT scan, which often leads to motion artifacts [ 45 ]. It is also important to consider the effect of radiation exposure in pediatric patients.…”

Coristoma óseo de la lengua: Reporte de un caso de etiología traumática

“…Esta patología se ha reportado con mayor frecuencia en mujeres, alrededor de un 70 % de los casos. La edad de los pacientes con coristoma óseo lingual es variado y ha sido reportado desde los 5 años hasta 73 años de edad con mayor frecuencia en la 3.ª y 4.ª década de edad 1,5,6 . Este caso reportado fue un paciente de sexo masculino de 65 años de edad al momento de la consulta.…”
