ABSTRACT
Hydatid cyst is a parasitic cyst caused by the tapeworm Echinococcus that occurs primarily in sheep grazing areas worldwide. It is a chronic disease, and the cysts can be localized in unusual anatomical and geographic locations. It is known to affect the head and neck region. Patients must undergo a thorough systemic investigation as 20-30% show multiorgan involvement. We report a case of hydatid cyst occurring in the buccal mucosa of a 45- year -old male presenting as a small asymptomatic lump and emphasize on its rarity and diagnostic issues.
ABSTRACT
Oral submucous fibrosis (OSMF) is a potentially malignant oral condition effectively linked to the causative habit of chewing areca nut. Since its first description in the 1950s, numerous epidemiological, biochemical, histological, and genetic studies have been reported. While most studies point out to the cause and effect of areca nut, co-additive factors are also implicated in the progression and malignant transformation of this condition. Biochemical investigations have concentrated on outlining such changes in the blood, serum or tissues of these patients and have given insights on the possible pathogenesis of OSMF. This article attempts to compile details of biochemical investigations in OSMF and summarize and infer on the findings.
