    Author: Martínez-Ortega JI, Gómez-Torres RE.

    Abstract:
    Oral focal mucinosis (OFM) is a rare connective tissue disorder that is characterized by the excessive production of hyaluronic acid due to myxoid degeneration of submucosal connective tissue. The disorder typically presents as an asymptomatic nodule or mass in the gingiva or hard palate, and OFM of the tongue is even more unusual. In this report, we present a case of OFM on the tongue in a 72-year-old female patient who presented with a symptomatic lump that had been growing for 6 months on the dorsum of her tongue. The patient reported discomfort and pain while speaking and swallowing, and the lump was visually apparent on examination. OFM is a benign condition that does not have any specific clinical or radiographical features that distinguish it from other more common oral lesions, such as lipoma or fibroma. Therefore, histopathological examination is essential for a definitive diagnosis. The management of OFM typically involves surgical excision of the lesion. In this case, complete surgical removal of the lesion under general anesthesia was performed, and the patient was followed up for 10 months postoperatively. During the follow-up period, there was no evidence of recurrence, and the patient reported significant improvement in her symptoms. In conclusion, OFM is a rare connective tissue disorder that can occur in the oral cavity. Although OFM of the tongue is even rarer, it should be considered in the differential diagnosis of oral lesions. Histopathological examination is essential for definitive diagnosis, and surgical excision is typically the preferred treatment modality.
