Cricoid chondroma presenting as upper airway obstruction: A report of a rare case

Laryngeal chondroma is a very rare laryngeal tumor that commonly presents as dysphonia and dyspnea. A combination of clinical, histological, and radiological data has paramount importance for accurate diagnosis of this rare disease. It is difficult to differentiate laryngeal chondroma from chondrosarcoma solely based on radiological imaging; therefore, radiologists need to specify the origin of the tumor and the level of extension. Here, we describe a case of a 60-year-old male patient who presented with upper airway obstruction. Radiologic imaging with a contrast-enhanced CT scan of the neck was done and showed a lobulated mass lesion with popcorn-like calcification arising from the endolaryngeal surface of the cricoid cartilage. An emergency tracheostomy was done, and at the same time, a biopsy was taken from the lesion intraoperatively.

Imaging of the Sinonasal Cavities

This article describes the various abnormalities that affect the sinonasal cavities and discusses inflammations, tumors, and tumor-like conditions. Specific imaging evaluations that focus on the sinonasal cavities are described in more detail.

International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors

BACKGROUND

Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field.

METHODS

In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication.

RESULTS

The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention.

CONCLUSION

As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.

Extra-axial Chordoma of the Sternoclavicular Joint

Chordomas are rare, slowly growing, aggressive primary bone tumors that originate from notochord remnants and occur almost exclusively in the axial skeleton. Here, we describe a patient with an enlarging right-sided neck mass that was later diagnosed as a sternoclavicular joint chondroid chordoma. En bloc surgical resection was accomplished with negative margins. The patient continues to do well 15 months after resection without radiotherapy. This case highlights the importance of considering a wide differential in managing sternoclavicular joint tumors.

Chondrosarcoma of the thyroid cartilage: surgical management of a rare case

Laryngeal malignancy encompasses about 1% of all cancers. Chondrosarcoma in the head and neck region represents about 0.1% of head and neck malignancies. Typical presenting symptoms relate to the anatomical location of these tumours and include dysphonia, inspiratory stridor, dysphagia, odynophagia or a neck mass. Benign and malignant cartilaginous cancers of the larynx have been described, and preoperative diagnosis can be difficult. Our report highlights the surgical management of a male patient in his 50s with chondrosarcoma of the thyroid cartilage.
