We present a case of a 60-year-old female patient who developed progressive hoarseness and shortness of breath. Hoarseness and shortness of breath developed progressively over a 2-mo period. The patient underwent resection of a laryngeal tumour 14 years before the aforementioned symptoms developed, and histopathological analysis indicated that it was a chondroma. The patient had suffered from hypertension for many years, with no significant hereditary diseases. She worked in administrative jobs and never smoked cigarettes or consumed alcohol. Palpatory examination of the neck during patient assessment revealed an oval-shaped tumour, which was predominantly located on the left side, approximately 6 cm in size, and fixed to the larynx wall. No enlarged lymph nodes were found. By indirect laryngoscopy, the left hemilarynx was found to be immobile and displaced medially, and the respiratory space was reduced. The mucous membrane was unchanged. Laboratory analyses were within the reference values. A computed tomography examination of the neck found a hypodense tumour, permeated with calcifications, up to 5.6 cm in diameter on the left, in the laryngeal wall in the subglottic segment, with no clear boundaries. The tumour infiltrated and partially destroyed the cricoid and thyroid cartilage. The tumour asymmetrically and significantly narrowed the lumen of the subglottic laryngeal segment. On computed tomography, no enlarged and pathologically altered lymph nodes were found, and there were no pathological changes in bone structure. A lung X-ray and abdominal ultrasound were performed, and no distant metastases were found. A portion of the larynx wall and a resected portion of the trachea were submitted for pathohistological analysis, with tumour tissue with a lobulated appearance, 6 cm × 4 cm × 2 cm in size, a whitish colour, homogeneous structure, and moderately solid consistency. The histology of the tumour tissue was dominated by a moderately abundant basophilic extracellular matrix, part of which had a myxoid appearance. The cellularity of the tumour tissue was moderately focal, with atypical, individual or organized smaller clusters and smaller chondrocytes with rare mitoses present in extracellular matrix lacunae. The tumour growth was nodulo-infiltrative.
