Abstract

sparkles

This case report highlights a rare instance of a soft-tissue chondroma located in the masticatory space, which is an unusual site for this type of benign cartilage tumor. The report documents the clinical presentation, imaging findings, surgical approach, and histological examination of a 47-year-old patient. The tumor was successfully excised using a mandibular swing approach, resulting in no recurrence or complications at the 12-month follow-up.

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.

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.

Chondroma of the mandibular condyle- rare location of a common benign cartilage tumour: case report and review of literature

International Journal of Otorhinolaryngology and Head and Neck Surgery, 2018

Chondroma is a benign tumour of mature hyaline cartilage.It is common in the tubular bones the hands and feetand conspicuous by its rarity in the mandible. We hereby present an interesting case of chondroma of the mandibular condyle that was managed in our department. The antecedent radiological findings and postoperative histopathological peculiarities of the case are discussed. This case also focuses the negligent attitude of our society towards one’s health problems until they are fraught with beliefs of cancer. Chondroma of the mandibular is a rare, benign slow growing tumour. Condylectomy is considered adequate treatment for all condylar masses. Surrounding margins of healthy soft tissue is also excised to prevent recurrences.

Radiological study of three cases of loose bodies in the temporomandibular joint

Brazilian Journal of Oral Sciences, 2010

According to the literature, loose bodies in the temporomandibular joint (TMJ) primarily prompt to synovial chondromatosis (SC). SC is a cartilaginous metaplasia of the mesenchymal remnants of the synovial tissue of the joints. Its main characteristic is the formation of cartilaginous nodules in the synovium and inside the articular space, described as loose bodies. The main symptoms are pain, limitation of jaw movement, crepitation and inflammation. Diagnosis is made by panoramic radiograph, computed tomography scan and mainly magnetic resonance imaging. SC is usually monoarticular. We report two cases of bilateral loose bodies in TMJ and one monoarticular evaluated through plain radiograph and cone beam volumetric tomography (CBVT). Clinical and radiologic findings are reviewed and discussed. References for diagnosis of SC affecting TMJ are supported. Patients presenting preauricular swelling, pain and restriction of TMJ movements should be evaluated with plain radiography, CBVT a...

Clinico-pathological conference: Lateral neck mass

CLINICAL PRESENTATION A 33-year-old woman presented with a painless swelling in the right submandibular region that had been enlarging pro-gressively over the past 1 and 1/2 years. There was no history of local trauma or infection, and the area did not change during meals. The medical and family histories were noncon-tributory. Physical examination revealed a soft, movable, poorly cir-cumscribed swelling measuring 5 5 cm in the right sub-mandibular area (Fig 1). The overlying skin appeared normal and did not appear to blanch significantly with compression of the mass. No bruit or thrill was detected. Intraorally, the floor of the mouth was nonelevated with a normal surface mucosa. Bimanual palpation elicited equivalent submandibu-lar salivary flow from both the right and left sides. Initial panoramic and mandibular occlusal radiographs failed to disclose any abnormal findings. On subsequent ul-trasound examination, the left submandibular gland appeared to be of normal size and echog...

Imaging and pathological correlation of soft-tissue chondroma

Clinical Imaging, 2006

The imaging findings (X-ray and MRI) and patterns of calcification of five patients with pathologically proven soft-tissue chondroma were correlated with histopathology. The size ranged from 0.5 to 3 cm. Four showed calcifications: curvilinear, punctuate, mixed curvilinear, and punctuate patterns, and the other one with a dystrophic or homogenous dense pattern showed hypointensity on T1-and T2-weighted MR imaging. Histopathology showed hyaline cartilage with nests of chondrocytes in the lacunae. Soft-tissue chondroma is a rare, benign softtissue tumor. It should be differentiated from other soft-tissue masses, especially malignancy.

Soft Tissue Chondroma of the Oral Cavity: An Extremely Rare Tumour Localized on the Hard Palate

Case Reports in Medicine, 2014

Chondromas are benign cartilaginous tumors usually localized within the tubular bones of the extremities. Soft tissue chondromas (STCs) are rare and only few cases have been reported in the oral cavity. The present case documents the exceptional finding of a 12-year-standing STC of the hard palate of a 63-year-old man. The tumor measured approximately 6 cm in its larger size and it was radically excised through the use of a quantic resonance molecular (QRM) lancet. No recurrence was observed during 1-year follow-up. A concise review of the relevant literature is included in the present paper.

Temporomandibular juxtaarticular chondroma: case report

Chondromas are benign tumours composed of mature hyaline cartilage. We present here the first case in the English language medical literature of juxtaarticular chondroma of the temporomandibular joint in the parotid region. Within the rarity of cartilage disorders of the temporo-mandibular joint (TMJ), this particular condition is a diagnostic curiosity. The patient, a 54 year old woman, presented a right preauricular tumour of 3.5 cm. which had been developing for 4 years. It was not painful but there was a recent symptomology of TMJ dysfunction, with pain and clicks. The diagnostic possibilities of a parotid pleomorphic adenoma and of a cartilage tumour of the TMJ suggested a difficult preoperative differential diagnosis, which influenced our approach regarding therapy. The tumour was excised, preserving the parotid gland. This enabled us to confirm the histological diagnosis of chondroma, composed solely of chondroide tissue. We have described the clinical characteristics of our case, and carried out a review of the relevant literature, emphasising the differential diagnoses.

Chondrosarcoma of the Temporomandibular Joint: A Case Report and Review of the Literature

Journal of Oral and Maxillofacial Surgery, 2010

Chondrosarcoma is a malignant tumor characterized by the formation of cartilage, but not bone, by tumor cells. Only 5% to 10% of chondrosarcomas occur in the head and neck, representing 0.1% of all head and neck neoplasms, with the larynx and the maxillo-nasal region being the most common sites. This report describes an unusual case of chondrosarcoma in a 54-year-old man who presented with pain and swelling in the left preauricular area. Computed tomography demonstrated a soft tissue mass in the left temporomandibular joint without causing erosion of the adjacent bony structures. The tumor was treated by excision in a single block with perilesional tissues, preserving the facial nerve. Histopathologic examination revealed chondrocytes with irregular nuclei with S-100 immunocytochemical staining positive in 30% of the tumor. The diagnosis was a grade I chondrosarcoma. There was no evidence of disease at the 16-month follow-up. The occurrence of chondrosarcoma in the temporomandibular joint (TMJ) is an exceptional event, with only 16 cases described. We report a case of this unusual entity and review the literature.

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.

Benign Tumors of Temporomandibular Joint

Temporomandibular Joint Pathology - Current Approaches and Understanding, 2018

The temporomandibular joint (TMJ) forms a complex functional system with teeth, bones, connected muscles and ligaments. Any discomfort in any of these structures directly affects the joint. The complaints are mostly pain, malocclusion and swelling. Temporomandibular joint tumors are very uncommon but show symptoms similar to intra-articular disorders that make up most of these disorders. The most common TMJspecific benign tumors are classified after a brief literature review. Our classification also includes the osteoma of the TMJ, other than World Health Organization's (WHO) classification of soft tissue and bone tumors. This benign tumor was also included in the classification because of its higher frequency in the literature. The treatment of these neoplasms may be conservative or radical surgery.

Expansile radiolucent lesion of the Temporomandibular Joint—A diagnostic enigma

Journal of Oral Biology and Craniofacial Research, 2017

Radiolucent lesions of Temporomandibular Joint (TMJ) represent a diagnostic challenge and a treatment conundrum. Biopsy of the lesions is technically difficult owing to their complex anatomy. The Differential Diagnosis (DD) includes a wide array of lesions including Simple Bone Cyst, Ameloblastoma, Central Giant Cell Granuloma, Hemangioma, Osteoblastoma, Osteochondroma, Chondroblastoma, Chondrosarcoma, Neurofibroma and metastatic malignant lesions though none has a specific predilection for TMJ. Here we present a case report of a large expansile radiolucent lesion of right TMJ in a 22 year old male patient with difficulties involved in diagnosis and management. Though cystic lesion of TMJ is uncommon it is incumbent on the Maxillofacial Surgeon for an early diagnosis and prompt management.

Extraskeletal chondroma: another diagnostic possibility for a soft tissue axillary mass in an adolescent

Case reports in orthopedics, 2011

Extraskeletal chondroma is a benign cartilaginous tumor that occurs predominantly in the soft tissues near small joints of the hands and feet. There are rare reports of the lesion in other sites, such as the head, neck, trunk, oral cavity, larynx, and pharynx. We present a case of an axillary mass in a 15-year-old girl who underwent MRI examination and resection, with the ultimate diagnosis of an extraskeletal chondroma, in order to expand the differential diagnosis of an axillary soft tissue mass in an adolescent.
