Chondrosarcoma of the Temporomandibular Joint: A Case Report and Review of the Literature (original) (raw)

A Case Report of Chondrosarcoma of Temporomandibular Joint

Indian Journal of Otolaryngology and Head & Neck Surgery, 2021

In this case report we describe a rare case of chondrosarcoma of the Temporomandibular joint in a 70 years old female who presented with a right preauricular swelling, trismus and neuralgic pain. On examination, firm and tender swelling was noted in the right preauricular region. CT Scan revealed 3.48 × 3.0 cm size mass lesion in the region of mandibular condyle and extending into the right temporomandibular joint space. The cytopathological report was suggestive of chondroid malignancy. The tumor was excised and histopathological examination showed large sheets of atypical tumor cells with cartilaginous matrix and diagnosis of a well differentiated Chondrosarcoma was confirmed. Post-surgical resection, patient remains disease free at 15 months follow up.

Chondrosarcoma of the temporomandibular joint

Otolaryngology - Head and Neck Surgery, 1999

Chondrosarcomas arise most commonly in the pelvis, femur, and humerus. The occurrence of this malignant osseous tumor in the head and neck region, especially the mandible, is rare. In 1986 Weiss and Bennett 2 reviewed the literature of chondrosarcoma involving the head and neck region and documented 161 cases, of which 56 involved the mandible. Even more rare is the occurrence of chondrosarcoma arising from the temporomandibular joint (TMJ). A current review of American and European literature revealed only 6 cases originating at the TMJ, the most recent of which was reported by Nitzan et al 3 in 1993. In this article an additional case of chondrosarcoma of the TMJ is presented. Pertinent clinical aspects, including presenting features, radiographic findings, histopathology, and treatment of chondrosarcoma of the mandible are discussed. Chondrosarcoma arising in the TMJ is emphasized because tumors at this site present a special management challenge because of the involvement of the cranial base and the temporal bone.

Chondrosarcoma of the temporomandibular joint: Case report

Head & Neck Surgery, 1987

Chondrosarcoma of the head and neck region is a rarely encountered tumor. Aggressive surgical excision offers the best chance for cure. In our case, combined diagnostic techniques consisting of fine needle aspiration (FNA), computed tomography (CT), and magnetic resonance imaging (MRI) made an accurate preoperative assessment possible and greatly influenced the treatment provided.

Dedifferentiated chondrosarcoma of temporomandibular joint: atypical features of a rare case

Journal of clinical and diagnostic research : JCDR, 2014

Chondrosarcoma (CS) is an uncommon malignant mesenchymal tumour showing cartilaginous differentiation which rarely presents in the jaws. CS represents 10-20% of all malignant bone tumours and less than 5% of tumours in head and neck region. Among the infrequent subtypes of CS, dedifferentiated CS is a sinister variant that presents with singular features and has extremely poor prognosis. We report a unique case of dedifferentiated CS that presented in the temporomandibular joint (TMJ) with extra articular involvement of the infratemporal space. This high grade CS is reviewed due to its rarity and the dentist is implored to take this variant into account when considering the differential diagnosis of destructive TMJ lesions.

Chondrocalcinosis: rare localization in the temporomandibular joint

The Journal of craniofacial surgery, 2006

In this paper introduces a rare case of chondrocalcinosis of the temporomandibular joint secondary to hyperparathyroidism, diagnosed in a 64-year-old man. The patient complained of symptoms characterized by the presence of a swelling in the left pretragic preauricular region, accompanied by a limitation of the mandibular movements. Radiographic examinations suggested a diagnosis of synovial chondromatosis. Subsequently definitive histological analysis removed mass stated for a chondrocalcinosis of the left temporomandibular joint. The differential diagnosis is very hard, in this case it has been difficult for the rarity of the pathology described in literature; the exact diagnosis can be only formulated on histologic and citologic examination of the mass excised.

Case report: Chondrosarcoma of the head and neck

Human Pathology: Case Reports, 2017

Chondrosarcoma originates in the bones of the head and neck. It is an unusual neoplasm that is slow-growing and represents only 1-3% of all cases of chondrosarcoma. Here, we report a case of a 45year-old male Caucasian patient treated at Hospital Amaral Carvalho with a history of swelling of the face and a tumoral mass in the right maxilla with infiltration into the skin, which had been present for 4 months. A computerized tomography (CT) of the face and sinuses demonstrated a lesion in the right maxilla. A maxilectomia without orbital exenteration was performed. It was diagnosed as a grade III chondrosarcoma, with infiltration into the subjacent bone, anterior wall of the maxillary sinus and floor of the orbit. The patient presented with recurrence of the tumor after adjuvant therapies. A molecular study on the present case showed an unusually large number of abnormalities. This finding demonstrated extreme chromosomal instability, which was likely due to the undifferentiation of the tumor. Although there are no cases in the literature with which to compare, these findings may elucidate potential therapeutic targets for advanced tumors without other therapeutic options.

Chondrosarcoma of the Mandible: A Case Report

Chondrosarcomas are malignant tumours of cartilaginous origin. They range from a well-differentiated growth resembling a benign cartilage tumour to a high-grade malignancy with aggressive local behaviour and the potential to metastasize. Only 5% to 10% of chondrosarcomas are known to occur in the head and neck region. A case of chondrosarcoma of the anterior region of the mandible is presented, along with a review of the relevant literature.

Surgical management of chondrosarcomas of Head and Neck

2016

Chondrosarcomas are uncommon malignant mesenchymal neoplasms that are rare in the head and neck region. They affect mainly the maxilla, while relatively few arise from the mandible, nasal cavity, larynx, skull and cervical vertebrae. Radical surgical resection with a wide margin of normal tissue is the treatment of choice, while radiotherapy and chemotherapy are reserved as adjunctive therapies for tumours where enbloc resection is not feasible. Introduction Chondrosarcomas are uncommon malignant mesenchymal neoplasms that are characterized by formation of cartilage derived from chondroid precursors. They account for 11-20% of all primary malignant tumors afflicting the human body. The sites which get affected at relatively high incidences, include – the long bones, the pelvis and the ribs. Approximately 1% to 3% of chondrosarcomas occur in head and neck region, affecting mainly the maxilla, while relatively few arise from the mandible, nasal cavity, larynx, skull and cervical verte...
