“…A study more accurate made in 2011 revealed that at least 108 cases had been reported in the English-language literature [17]. However, coronoid process and the medial aspect of the condyle are the most commonly affected areas [7,9,10,12].…”

“…Complementary examinations such as panoramic radiography and computed tomography (CT) can be useful to visualize the existing relationships among anatomic structures [18]. Other useful examination includes scintigraphy to evaluate the presence of multiple lesions [17]. Approximately 75% of the patients with osteochondroma develop solitary lesions while 25% have multiple lesions.…”

Objective: This article presents an interesting case of osteochondroma of the the sigmoid notch. Case Report: A 15-year-old female with severe facial asymmetry, malocclusion, open bite and extreme limitation of mouth opening. Panoramic radiography showed an exophytic radiopaque mass arising from the sigmoid notch on the right side. CT images revealed bony proliferation with benign signs causing damage to the articular eminence, condilar morphology and periarticular soft tissue calcifications. Magnetic Resonance confirmed the findings of the CT and revealed modifications on disc morphology. A surgical resection was performed. Conclusion:The OC located at the sigmoid notch presented is probably the rarest site seen in the existing literature.Key words: Osteochondroma; Sigmoid notch; Facial asymmetry; Restricted mouth opening Osteocondroma do sulco sigmoide: relato de caso em uma localização rara RESUMO Objetivo: O presente artigo apresenta um caso interessante de osteocondroma (OC) no sulco sigmoide. Relato do caso: Paciente do sexo feminino, com 15 anos de idade, apresentada assimetria facial severa, mal oclusão, mordida aberta e restrição severa da abertura bucal. A radiografia panorâmica evidenciou a presença de uma massa radiopaca exofítica, partindo do sulco sigmoide do lado direito. Imagens de tomografia computadorizada (TC) evidenciaram a presença de proliferação óssea, com características benígnas, causando alterações na eminência articular, morfologia condilar e calcificação dos tecidos moles peri-articulares. A ressonância magnética confirmou os achados da TC com relação à alteração da morfologia do disco articular. Como tratamento, foi realizada a ressecção cirúrgica. Conclusão: O OC localizado no sulco sigmoide, apresentado no presente relato de caso, é provavelmente a localização mais rara citada na literatura.

“…Though it is one of the most common benign tumours of the condyle, it is most frequently found on long bones and is uncommon on the skull [2]. OC of the mandibular condyle is thought to be a relatively rare lesion and only 90 cases are documented in the English literature to date [3].Clinically, the common manifestations of the tumour include facial asymmetry, hypomobility, deviation of mouth opening, malocclusion, including ipsilateral posterior open bite and contralateral cross bite, pre-auricular swelling, TMJ pain, clicking sound, and recurrent joint dislocation [4]. Radiographic appearance of OC of the mandibular condyle can be pathognomonic, appearing as an irregularly shaped, mixed density, expansile lesion.…”

A 36-year-old male patient presented with complaints of speaking and eating difficulties. He had a history of previous steroid injection to left TMJ a year ago for the management of internal derangement and from that time he slowly developed pain in the left TMJ associated with slight facial asymmetry [Table/ Fig-1]. Patient gave history of steroid injection (single dose) one year back due to lock jaw problem following which he developed pain and facial asymmetry. There was no history of trauma. Medical and family history was not significant. On clinical examination facial asymmetry was present and a localized swelling was present on left TMJ area which was diffuse, tender and hard in consistency. Tenderness elicited on TMJ area on opening and closing mouth and deviation of mandible on right side was present on mouth opening. Inter-incisal mouth opening was 30 mm. Radiographic examination revealed slight erosive lateral surface of left condyle and obliteration of left TMJ space on panoramic radiograph [Table/ Fig-2]. Clinic-radiographic correlation lead to following differential diagnosis: benign bone tumour of left condyle, fibrous ankylosis of left TMJ. As patient was not willing for advanced imaging, surgical exploration of joint was done where thick cartilaginous material was encountered at head of left condyle . Complete surgical excision of lesion was performed. On gross examination the specimen was measuring 1 × 0.5 cm in size, brownish white in color, firm in consistency. Postoperatively patient's mouth opening improved to 37mm.Microscopic examination revealed mono-nucleated, bi-nucleated and multi-nucleated cells having round to oval hyperchromatic nuclei within lacunae, suggestive of chondrocytes dispersed in hyaline ABStRACtOsteochondroma (OC) is one of the most common benign condylar tumours having both chondroma and osteoma. However, this tumour is most frequently found on the metaphyses of long bones and is unusual on the skull. When it affects the mandibular condyle, the cause could be due to trauma to the tempero mandibular joint (TMJ). Here, in this report we present a rare case of osteochondroma of left condyle region in a 36-year-old man. The patient had noticed pain in the left TMJ for six months. The lesion is surgically removed and histologically evaluated which composed of chondrocytes dispersed in hyaline matrix along with a rim of calcified bone at one end.matrix [Table/ Fig-4&5]. Areas of hemorrhage were also evident with minimal peripheral bony area. All these features confirmed the diagnosis of OC. Patient is on regular follow up. DISCUSSIoNThe World Health Organization defines the OC as a "cartilage-capped bony protrusion on the external surface of bone.'' It represents approximately 35% to 50% of all benign bone tumours and 8% to 15% of all primary bone tumours [1]. Though it is one of the most common benign tumours of the condyle, it is most frequently found on long bones and is uncommon on the skull [2]. OC of the mandibular condyle is thought to be a relatively rare lesion and o...
