Oral Focal Mucinosis in a Patient From Hail, Saudi Arabia: A Case Report of a Rare Gingival Lesion.

Oral focal mucinosis (OFM) is an uncommon, benign condition of the oral cavity marked by localized myxoid degeneration of the connective tissue. This report presents a highly unusual case of a large OFM localized to the maxillary gingiva of a 55-year-old female patient in Hail, Saudi Arabia. Because its clinical appearance closely mimics reactive overgrowths like pyogenic granuloma, establishing a clinical diagnosis is difficult. Consequently, definitive diagnosis relies entirely on histopathologic assessment. While gingival OFM remains exceedingly rare, it should be routinely included in the differential diagnosis of exophytic oral masses.
