Juxtacortical chondroma of the hyoid bone. Report of a case

Hyoid Chondroma

Mass lesions of the larynx are one of the most common clinical entity which we come across in routine otorhinolaryngology and head neck practice with varied symptomatology. Among all the mass lesions of the larynx, Epithelial neoplasms constitute up to 97%. Mesenchymal tumours of the larynx constitute only 0.3-1.0% of all the laryngeal tumors. Abundance of cartilage structures in the larynx made it a spot for mesenchymal tumors [chondromas and chandrosacrcomas]. The spectrum of mesenchymal neoplasms can vary from chondromas, chondroblastoma to chondrosarcoma. Here we want to share our experience of a mesenchymal tumour of the larynx. This case is reported for the rarity and ambiguity in diagnosis. Though these are slow-growing tumours with an early presentation, in our case, the patient had a supportive tracheostomy without definitive treatment for more than 2 years. We managed this patient by excising the mass by lateral pharyngotomy with the preservation of larynx followed by successful Decannulation in 20 days.

Chondrosarcoma of the hyoid bone: A diagnostic pitfall in the submandibular region

Chondrosarcoma is a malignant chondroid matrix-producing neoplasm which usually presents in the bones of the pelvis, followed by the proximal femur, proximal humerus, distal femur and ribs. The occurrence of this lesion in the hyoid bone is exceedingly rare, with only a few reported cases, and its diagnosis by fine-needle aspiration cytology (FNAC) in this particular location, to our knowledge, has never been addressed. Furthermore, the sampling of chondroid matrix at this site can pose a diagnostic dilemma with other lesions of the submandibular region. This report describes the clinical, radiologic and cytologic features on FNAC of a chondrosarcoma of the hyoid bone, emphasizing the diagnostic pitfalls of this entity and expanding the cytologic differential diagnosis of tumors of the submandibular region.

Hyoid chondroma presenting as an external neck mass

Chondromas of the larynx are rare neoplasms; only a few examples of cartilaginous tumors affecting hyoid bone have been reported. A 33-year-old woman presented with a neck mass on the left carotid triangle. The patient's computed tomography and magnetic resonance imaging revealed a heterogenous mass, which seemed to originate from the left greater cornu of hyoid. The mass was excised using a transcervical approach with left greater cornu of hyoid bone. The pathologic diagnosis was chondroma of hyoid. Expert radiologic and pathologic review is mandatory in cartilaginous neoplasms of the larynx. Cartilaginous neoplasms of the hyoid should be included in the differential diagnosis of neck masses at the carotid triangle.

Chondroma of the hyoid bone: a case report

Chondroma of the hyoid bone is extremely rare. We report the case of a 24-year-old woman with a chondroma of the greater cornu of the hyoid bone. In addition, we discuss the clinical and pathologic differential diagnoses.

Parosteal chondrosarcoma attached to the hyoid bone. A case report

A parosteal chondrosarcoma with low-grade malignancy attached to the hyoid bone in a 66-year-old man is reported. The tumor was considered to present a low-grade malignancy because slight invasion into the surrounding soft tissues and rapid growth were observed. Four years after initial surgery he had a local recurrence. To the best of our knowledge, this is the first reported case of parosteal chondrosarcoma in this location.
