Nasofrontal masses belong to the group of congenital midface anomalies (CMFA) in paediatric age group. The usual list of differential diagnosis for such masses can be narrowed to Frontonasal dermoid, epidermoid, nasal encephalocele and nasal gliomas. Frontonasal dermoid with patent dermal sinus tract is a rare craniofacial anomaly resulting from the failure of normal embryonic development. Most of patients present in infancy or early childhood. CT, MRI and sinogram together are usually required for definitive diagnosis. Knowledge of embryonic development of nose & anterior skull base is important in understanding the pathologies of Frontonasal masses. Endoscopic 'key-hole' approach to these lesions via small incision allows better visualization & ensures complete removal.

ABSTRACT:The parotid glands are paired salivary glands situated on either side of the face, between ear and ramus of mandible. The main trunk of facial nerve enters the posterior surface of the gland and quickly bifurcates into upper and lower divisions, which arbitrarily define the superficial and deep lobes of the parotid gland. There is no histological demarcation between these two lobes. We hereby present a case of a tumor that pathologically lead to anatomical division of the parotid gland.HOW TO CITE THIS ARTICLE: Naresh V. Dawat, Pooja Sancheti, Haritosh K. Velankar, Sharad B.

INTRODUCTION Oral squamous cell carcinomas (OSCC) are frequently preceded by or associated with leucoplakia, erythroplakia, oral submucous fibrosis or lichen planus. The standard method of revealing PML potentially malignant lesions of oral mucosa or submucosa is usually done via conventional oral examination (COE), direct visualisation and biopsy with the aid of imageenhanced endoscopy along with high-resolution imaging system. In view of the promising results of using Narrow Band Imaging as a screening aid in cancer screening, a prospective randomised study was performed to evaluate statistically the efficacy of NBIS in diagnosis of potentially malignant lesions in oral cavity using histopathology as gold standard. METHODOLOGY 236 potentially malignant lesions in oral cavity from 195 patients underwent Broadband white light & NBI-endoscopic evaluation according to the Inoue's classification. The histopathology results were compared with Broadband white light & Narrow Band light evaluation. RESULTS The sensitivity, specificity, positive predictive value, negative predictive value and clinical accuracy for the detection of oral potentially malignant disorders or worse by Narrow Band Imaging were 96 %, 83%, 96%, 83% and 93.22 % respectively. The sensitivity, specificity, positive predictive value, negative predictive value and clinical accuracy with conventional broadband white light oral examination were 72%, 63%, 88%, 36% and 70.33% respectively for the detection of oral potentially malignant disorders.

Lymphangiomas are fluid-filled thin-walled cysts formed due to malformations in the lymphatic system. It is usually seen in children and is rarely present in adults. Majority of the cases of lymphangiomas are seen in head and neck region with occasional extension in mediastinum. We present a case of an adult with macrocystic lymphangioma in the left posterior triangle of neck. FNAC and MRI are important modalities of investigation for diagnosis of lymphangioma. Surgical excision is the main modality of treatment in case of macrocystic lymphangioma. In case of a soft cystic swelling in head & neck region, a differential diagnosis of lymphangioma should be kept in mind.

Frontoethmoidal mucocele can present with a multitude of different symptoms including ophthalmic disturbances. Though benign, they have a tendency to expand by thinning the bony walls. They displace and invade surrounding structures by pressure and bony resorption. If it invades the orbit and continues to expand, the mass may mimic the behavior of many benign growths arising primarily in the orbit. We report a case of a frontoethmoidal mucocele extending into the orbit. Clinically, the patient had an insidious onset of clinical presentation with no intracranial symptoms.
