Long‐Term Follow‐Up of Cartilaginous Tumors of the Larynx

Abstract

Based on this small series of patients, the long-term follow-up of benign and low-grade malignant tumors suggests that the surgical approach and prognosis does not depend on histologic distinction and, importantly, underdiagnosed malignancy on tumor sampling and recurrent chondrosarcoma, managed with salvage surgery, have no adverse impact on patient survival. Total resection of the cricoid cartilage with thyrotracheal anastomosis over a stent proved an alternative surgical technique in chondrosarcoma who otherwise would have been treated by total laryngectomy.

Chondrosarcoma of the larynx: Report of one case and review of the literature

“…Moreover, the first sign of the posterior cricoid involvement may be the stiffness of the vocal cords, due to the blockage of the cricothyroid articulation arytenoidic and not because of the infiltration of the recurrent nerve [10,11].…”

Arytenoid Chondroma

“…No cause has been defined, but it has been suggested that abnormal ossification process occurring later in life may contribute to their development [7]. Chondromas and "low-grade" chondrosarcomas are the most common of these tumors [3].…”

“…There is controversy as to the frequency of chondromas in relation to chondrosarcomas, and prevalence is difficult to determine because of their rarity. Traditionally, the percentage of chondromas has been estimated at around 72-80% [7]. However, there are conflicting reports in the literature.…”

“…However, there are conflicting reports in the literature. Studies have found chondrosarcomas to account for as high as 67% or as low as 30% of cartilaginous tumors [3,7]. Furthermore, long-term follow-up studies have shown that lesions diagnosed initially as chondromas may develop into chondrosarcomas potentially explaining this discrepancy [1,7].…”

“…Arytenoid cartilages are made up of both elastic and hyaline cartilage, with the vocal process consisting of elastic cartilage [7]. Chondromas frequently occur in hyaline cartilage and rarely develop in elastic cartilage, explaining why they may be less likely to occur in the mixed arytenoid cartilage [7].…”
