Clear cell odontogenic carcinoma: a diagnostic and therapeutic dilemma

BACKGROUND: Clear cell odontogenic carcinoma is a rare odontogenic tumor occurring in the anterior region of the mandible in 5(th)–7(th )decades and shows a female preponderance. It is potentially aggressive, capable of frequent recurrences and loco-regional and distant metastases. CASE PRESENTATION: A 45- year- old woman presented with a radiolucent left mandibular swelling associated with loss of teeth. Left cervical lymph nodes were enlarged on palpation. The patient underwent resection of the tumor but consequent to resected margins being positive for tumor cells underwent left hemimandibulectomy with ipsilateral functional neck dissection and was free of recurrence at 8 months follow-up. CONCLUSION: Clear cell odontogenic carcinoma should be considered in the differential diagnosis of jaw tumors with conspicuous clear cell component. Curettage or conservative resection inevitably results in recurrences and/or metastasis and more radical resection is warranted in these tumors, especially when they are large and show soft tissue invasion

Glandular Odontogenic Cyst: Report of Two Cases and Review of Literature

Glandular odontogenic cyst (GOC) is an uncommon jaw bone cyst of odontogenic origin described in 1987 by Gardner et al. It is a cyst having an unpredictable and potentially aggressive behaviour. It also has the propensity to grow to a large size and tendency to recur with only 111 cases having been reported thus far. The first case occurred in a 42-year-old female and presented as a localized swelling extending from 19 to 29 regions. There was a history of traumatic injury at the site. There was evidence of bicortical expansion and radiographs revealed a multilocular radiolucency. The second case occurred in a 21-year-old male, as a large swelling in the mandible and radiograph revealed radiolucency in the region. On histopathological examination, these lesions were diagnosed as GOC. It was concluded that, two cases submitted by us correlate with the existing literature that GOC’s affect more commonly in the middle age group, having predilection for mandible and that trauma could be a precipitating factor for its occurrence. The increased recurrence rates can be due to its intrinsic biological behavior, multilocularity of the cyst, and incomplete removal of the lining following conservative treatment

Mouth cancer: presentation, detection and referral in primary dental care

Mouth cancer can present as a variety of abnormalities and visible changes affecting the oral mucosa, including ulceration, swelling and areas of erythema. The five-year survival from mouth cancer is poor at approximately 50%. Detection of the cancer while less than 2 cm in diameter with no metastasis greatly improves the outcome for the patient. Although many cancers in the mouth develop from what was previously an apparently normal mucosa, some arise in pre-existing conditions that are therefore regarded as potentially malignant. Regular assessment of the soft tissues within the mouth and the neck for the presence of abnormalities is an essential component of primary dental care. Any persistent and unexplained abnormality requires referral for definitive diagnosis and specialist management
