摘要

Choristomas are tissues or cells that are normal when viewed microscopically but exist in locations in the body where such tissues or cells should not be found. Cartilaginous choristoma (CC) was first described by Berry in 1890. The tonsillar localization of a choristoma is extremely rare. In our study, we aimed to contribute to the identification of rare cases of tonsillar cartilaginous choristoma, to determine the frequency, age of occurrence, and gender distribution, and to review differential diagnoses, and to detect concurrent lesions. Material/Method: This study is a retrospective analysis covering 3 years from the archives Pathology Laboratory (March 2021–March 2024). Patients undergoing tonsillectomy or adenotonsillectomy from these dates were identified. The patients’ age, gender, surgical procedure, and the specimens’ histopathological results were analyzed. Results: CC was detected in 26 cases (0.59%). It occurred in 11 cases (42.3%) on the right side, 7 cases (26.9%) on the left side and 3 cases (11.5%) with CC on both sides. In 5 patients (19.2%) it was impossible to identify to which side the detected CC belonged since the tonsils were packed into another jar. Of the cases, 12 (46.2%) were females and 14 (53.8%) were males. The age range was 5–29 years (mean age 10 years). Conclusion: Although malignancy detection rates are low in the studies, we believe histopathologic examinations are essential for detecting benign lesions, as in our case. We also think that more studies are required to establish whether the likelihood of detecting choristoma increases with an increasing number of samples taken.
