Oral Focal Mucinosis of the Gingiva: Case Report

Background: Oral focal mucinosis is a rare disease of unknown etiology, where the connective tissue undergoes a focal myxoid degeneration.Methods: We describe a 48‐year‐old patient who was referred for a firm, tender mass located on the gingiva of the left central mandibular incisor. The first clinical impression at examination was that of a periodontal abscess.Results: The lesion underwent a biopsy, and the final microscopic diagnosis was oral focal mucinosis.Conclusions: It must be stressed that in most focal gingival lesions, a preoperative diagnosis can be almost impossible.
