The oral cavity mucosal tissue alteration can manifest in a variety of lesions where great majority of localized overgrowths of the oral mucosa are considered to be reactive rather than neoplastic in nature. Many of these lesions can be identified as specific entities on the basis of their histopathological features. In our present study, we have evaluated the various benign lesions of oral cavity with emphasis on relative frequencies, types and distribution of lesions.
MATERIALS AND METHODSAll the benign lesions of oral cavity diagnosed by histopathology in the Department of Pathology, K. S. Hegde Medical Academy of Nitte University over a period of two years from July 2012 to June 2014 were retrospectively studied. Paraffin tissue blocks were collected from Histopathology Department and 5 microns thick. Sections stained with Hematoxylin and Eosin were studied by histopathologist.
RESULTSA total of 124 cases were analyzed during the study period. The age group ranged from 8 to 86 years in the study with a mean age of 63.9 years. Buccal mucosa was the most common site involved in 44(35.5%) cases. Benign lesions of oral cavity included inflammatory/infective lesions in 30(24.2%) cases, traumatic/hyperplastic in 30(24.2%), cystic in 10(8%) developmental lesions in 16(13%), pre-malignant lesions comprising of leukoplakia and erythroplakia in 20(16%) and benign neoplastic lesions constituted in 18(14.6%) cases. Leukoplakias are the common benign lesions of the oral cavity followed by hemangiomas, hyperplasia and squamous papilloma. In the buccal mucosa, most common lesions were leukoplakia and lichen planus.
CONCLUSIONThe increased frequency of benign neoplastic lesions (14.6%) in our study and less (4%) as compared to other author is possibly due to limited sample size in ours as contrast to large population based study by them.
BACKGROUNDDermatophytes are among the common fungal agents causing superficial skin infections worldwide. They affect about 20-25% of the world population and the causative agents of these infections vary from place to place. The present study was aimed at finding out the clinicomycological pattern of dermatophytosis, aetiological agents, comparing the clinical diagnosis with laboratory investigations and the clinicomycological cure following treatment. Terbinafine is well tolerated on topical administration and has low potential for drug interactions. In clinical trials, mycological and overall efficacy rate of topical terbinafine is around 80% and with an intermittent pulse dose therapy, cure rate of around 90% has been reported.
ABSTRACT:Choanal atresia is an uncommon and poorly recognized cause of unilateral nasal obstruction in adults. We discuss here two cases of unilateral choanal atresia, one adult and a child. Both of them had nasal obstruction as their chief complaint. Both patients underwent a Trans nasal endoscopic excision of choanal atresia with assistance of powered instrument and repair of the choana with stent. Both the patients were followed up regularly for a period of one year and were found to be symptom free with a well healed and patent choana. These case reports highlight the possibility of considering choanal atresia as a differential diagnosis in all patients presenting with unilateral nasal obstruction. CT scan and Nasal endoscopy are the investigations of choice. Trans nasal endoscopic approach with stenting provides an excellent method of management.
