The Clinical Analysis Of Laryngeal Chondroma (And Nine Literatures Review)

OBJECTIVETo study the clinical,pathological,imaging features and treatment of the laryngeal chondroma.METHODSTen cases of the laryngeal chondroma were reviewed and analyzed in the mainly clinical,pathological,imaging features and treatment.RESULTSIn the ten cases,the endogenous chondromas were 7,while the exogenous ones were 3.The patients were 6 in male,4 in female,aged 3 to 63 years old.Three patients with exogenous chondroma manifested a cervical mass.There were four cases manifested hoarseness and dyspnea,one manifested dyspnea and cough,one case manifested dyspnea only,one case with none symptom in the 7 patients with endogenous chondroma The tumors were found in the cricoid cartilage in the 7 endogenous ones.Three exogenous ones were in the thyroid cartilage.There was calcification in 5 cases in the X ray imaging.All patients undergone surgical operation. CONCLUSIONLaryngeal chondroma is rare.The etiology of laryngeal chondroma is uncertain. It has many methods in its classification.It occurs in all the laryngeal cartilage,but most frequent site affected is the cricoid ring,followed by the thyroid,and more rarely the arytenoid and epiglottis cartilages.The clinical presentation is varied and directly dependent on the size and location of the tumor.Patients with endogenous tumor always suffer from hoarseness and dyspnea.Exogenous ones can produce a neck mass.Calcification in the soft tissue is one of the characters of the laryngeal chondroma in the imaging feature.Histologically,laryngeal chondromas show a homogenous,monotonous pattern,with low cellularity,no more than 30 to 40 nuclei per high-power field.The nuclei are described as typical,with no apparent mitoses.It is difficult to distinguish between low-grade chondrosarcomas and chondroma of larynx.Surgical extirpation is the mainstay of therapy.
