Clear Cell Odontogenic Carcinoma: A Rare JAW Tumor-A Case Report and Literature Review.

Clear cell odontogenic carcinoma (CCOC) is a rare epithelial malignant odontogenic tumor of the jaw with a distinct histology and deceptive behavior. As the clinical presentation is often misleading, the contribution of biopsy, molecular biology, immunohistochemistry and cytogenetics are essential in the diagnostic process. This article describes the presentation of an aymptomatic, painless swelling in the lower jaw of a 63 yrs old female, who was initially diagnosed as an ameloblastoma, taken up for segmental resection, subsequently histopathologically diagnosed as a case of clear cell odontogenic carcinoma and later managed with chemotherapy. Current management protocols and presentation of CCOC have also been reviewed.

Post-Covid Orofacial Mucormycosis: A Clinico-Radiological Classification System and Management Protocol.

Background: In the wake of the second wave of the COVID-19 pandemic, a substantial number of individuals were afflicted by orofacial mucormycosis post-COVID. The immunocompromised state rendered by the SARS-COV2 (Severe Acute Respiratory Syndrome Corona Virus 2) infection provides a breeding ground for the opportunistic mucor invasion. Corticosteroid and COVID-induced hyperglycemia contribute to the unhindered progress of the mucor infection in these patients. The sino-nasal region serves as the entry point and rapid progress of the disease to the oral cavity, mid-face, orbits, and ultimately the brain proves fatal. Aim and Objectives: The aim of this study was to present a definitive clinico-radiological staging/classification system for patients of post-covid mid-face mucormycosis based on combined radiographic and clinical features for subsequent convenient staging of maxillofacial mucormycosis. The objectives are being to lay down a comprehensive management protocol for these patients. Methods: This retrospective study consisted of a cohort of 31 patients presenting to a tertiary care center over a 12-month period and diagnosed as post-covid mucormycosis. Their clinical features at the time of presentation along with radiographic presentation/extent of anatomical destruction were combined to create a clinico-radiological staging system. Further, a comprehensive management protocol including cultures, surgery and chemotherapy has been laid down. Results: This included 18 males and 13 females. Average age of the patients was 53.5 years. As per the clinico-radiological system formulated by the authors, 2 patients (1 males and 1 females) displayed features of Stage 0, 12 patients (7 males and 5 females) of Stage 1-A, 8 patients (5 males and 3 females) of Stage 1-B, 6 patients (4 males and 2 females) and 3 patients (1 male and 2 females) of Stage 3. Conclusion: The lacuna of a comprehensive staging/classification system for patients of maxillofacial mucormycosis was felt by the authors while treating those affected by post-covid mucormycosis along with a detailed algorithm for management of the study population. It is to this effect that this clinic-radiological classification system has been suggested by the authors along with a management protocol.

Melanotic Neuroectodermal Tumour of Infancy - A Case Report and Review of Literature.

Rationale: Melanotic neuroectodermal tumour of infancy (MNTI) is universally described as a rare, benign, pigmented lesion which most frequently involves the maxilla. Its origin is well established to be in the neural crest cells. Due to the high recurrence rate and aggressive behaviour mimicking malignancy, it poses a great challenge in their diagnosis, treatment planning, and prognosis. Patient Concern: Two-year-old female with no known comorbidities was brought in with the chief complaint of a growing swelling in the upper lip region. Diagnosis and Treatment: She was taken up for resection of the tumour under general anaesthesia. The specimen was subjected to histological and immunological examination confirming the diagnosis of MNTI. Outcome: The postoperative period was uneventful. After regular follow-up, the patient showed satisfactory healing with no signs of recurrence. Take-Away Lessons: Based on our experience, we feel that the diagnosis of MNTI is mainly clinical. Early conservative surgical excision and regular follow-up provide an excellent result with good prognosis.

Pleomorphic adenoma palate: Major tumor in a minor gland.

Pleomorphic adenoma (PA) is the most common benign mixed salivary gland neoplasm that accounts for 60% of all benign salivary gland tumors. It has diverse histological presentation and occurs in both major and minor salivary glands. PA of minor salivary gland in the palate is a common entity. We report the case of a 45-year-old female who presented with a painless slow growing swelling of palate over the last 20 years. The mass was extending to oropharynx causing mechanical obstruction of airway. Magnetic resonance imaging (MRI) depicted an oval-shaped mass occupying oropharynx and displacing the tongue inferiorly. Fine needle aspiration cytology (FNAC) was suggestive of PA. The entire tumor mass was excised along with overlying mucosa. Histopathological examination confirmed diagnosis of PA of minor salivary gland. There has been no recurrence of the lesion since 1 year.

Role of split calvarial graft in reconstruction of craniofacial defects.

The aim of this study was to evaluate the clinical applications, graft uptake, and complications of split-thickness calvarial graft for the reconstruction of craniofacial defects.This retrospective study included 26 patients with craniofacial defects treated between January 2008 and December 2009. This included 17 male and 09 female patients between 9 and 45 years. Depending on the treatment provided, the patients were divided into 3 groups. Group 1 included 11 patients with cranial defect operated on for cranioplasty. Group 2 included 7 patients with orbital floor defect operated on for orbital floor reconstruction, and group 3 included 8 patients with alveolar cleft defect operated on for secondary alveolar grafting. Clinicoradiologic follow-up ranged from 18 to 24 months.In group 1, the symmetry of the calvarium was restored with good cosmesis. Improvement in neurologic function was observed in 7 patients. In group 2, the orbital volume and ocular function was maintained. In group 3, graft uptake was satisfactory with increase in bone density, and continuity of the alveolar bone was maintained. Cuspid eruption was aided orthodontically.Split calvarial grafts are suitable materials for craniofacial reconstruction. Their embryological origin, thickness, and shape are ideal for the restoration of craniomaxillofacial defects.
