“…Osteochondroma is usually distinguishable by demonstrating both medullary continuity with the central portion of the lesion and a cartilage cap [9]. Malignancies with mineralised extra-osseous components such as conventional osteosarcoma and chondrosarcoma should also be considered, given their relative propensity for the long bones [10].…”

“…It is critical to distinguish benign tumors from aggressive malignancies such as chondrosarcoma or periosteal osteosarcoma. Radiographic features concerning for malignancy include heterogeneous density and irregular margins suspicious for periosteal osteosarcoma, and ring-and-arc calcifications and cortical erosion suspicious for chondrosarcoma [5]. In this case, the preoperative imaging could not differentiate between a benign or malignant lesion, so histopathologic analysis was required for definitive diagnosis.…”

Introduction. Osteochondromas are relatively common benign bone tumors often located at the metaphyseal ends of long bones; however, they are rare in the head and neck region. The objective of this study is to present a case of an osteochondroma arising from the thyroid cartilage causing insidious dysphonia and to present a literature review. Methods. The medical record of a patient treated for osteochondroma of the thyroid cartilage was reviewed. A literature search on osteochondromas was conducted using PubMed and Google Scholar. The epidemiology, presentation, diagnosis, treatment, and outcomes of osteochondromas were reviewed. Results. A 50-year-old female presented with nine months of dysphonia and aphonic voice breaks. Laryngovideostroboscopy revealed a left false vocal fold fullness, glottal gap, and vibratory phase asymmetry. A CT neck demonstrated a well-circumscribed 5 × 8 × 9 mm mass arising from the left thyroid cartilage lamina with a thin calcified rim and a heterogeneous decreased attenuation center. The tumor was excised surgically. Histopathologic analysis demonstrated hyaline cartilage overlying lamellar bone with fatty bone marrow, consistent with osteochondroma. English language literature review revealed no cases of osteochondroma of the thyroid cartilage. The presenting features of osteochondroma may depend on the size and location of the lesion. It is critical to differentiate between benign and malignant bone tumors, and physicians must rely on their clinical examination, radiographic findings, and histopathologic analysis to make the correct diagnosis. Conclusions. Osteochondromas of the laryngeal framework are extremely rare, and to our knowledge, there have been no reports in the literature of this tumor arising from the thyroid cartilage. Dysphonia may be the presenting symptom in a patient with a thyroid cartilage mass causing restricted mobility of the true vocal folds.

“…Surface osteosarcomas comprise approximately 4–12% of all osteosarcomas. 5 , 9 They comprise three distinct entities, namely the parosteal (PAO), the periosteal (PEO) and the high-grade surface osteosarcoma (HGSO). 6 The parosteal and periosteal subtypes are more common than HGSO.…”

“…They tend to affect older patients compared to their conventional intramedullary counterparts. 5 They arise on the outer cortical surface; however, the presence of intramedullary (IM) extension does not rule out a surface tumour as a small percentage have IM extension. They may invade or displace neurovascular bundles, tendons or ligaments in close proximity.…”

Surface bone sarcomas: an update on current clinicopathological diagnosis and treatment

Surface bone sarcomas are rare malignant bone tumours. Osseous and cartilaginous surface bone sarcomas are the most common, with parosteal and periosteal osteosarcomas, periosteal chondrosarcomas and secondary peripheral chondrosarcomas being the most frequent. Their clinical symptoms are non-specific and include pain for several months, swelling and limited range of motion of the adjacent joints. Prompt diagnosis is important, as biological behaviour, imaging and histopathologic characteristics, treatment and prognosis differ considerably from their conventional intramedullary counterparts. Moreover, their imaging characteristics are not infrequently non-characteristic and may be misinterpreted as juxtacortical benign lesions leading to incorrect diagnosis and treatment, with life-threatening repercussions. Molecular studies and histopathological sampling are essential for accurate diagnosis. There are still numerous issues regarding the biology, pathophysiology and treatment options of these entities due to their rarity. Cite this article: EFORT Open Rev 2021;6:905-917.
