Oral focal mucinosis an oral counterpart of cutaneous focal mucinosis, is a rare disease of unknown etiology. Its pathogenesis may be due to the overproduction of hyaluronic acid by a fibroblast, at the expense of collagen production, resulting in focal myxoid degeneration of the connective tissue, primarily affecting the mucosa overlying the bone. Oral focal mucinosis occurs predonderantly in adults during the fourth and fifth decade of life, although it has been reported sparingly in children and adolescents. It has no distinctive clinical features, as the diagnosis is solely based on the histopathological features and treatment involves complete surgical excision. Recurrence is unreported. This case report put forward the clinical and histological presentation and consequent management of Oral focal mucinosis in an adolescent female patient.
