Oral Focal Mucinosis: A Case Report and Review of the Literature

Abstract

Oral focal mucinosis (OFM) is a rare benign lesion of the oral mucosa, first characterised by Tomich in 1974. It is widely considered the oral counterpart of cutaneous focal mucinosis or myxoid cyst. We present a new representative case of OFM in a young adolescent patient, along with a comprehensive review of the literature from the original description to recent reports. Clinically, OFM typically presents as a slow-growing, painless, pinkish soft-tissue nodule on keratinized mucosa (most often gingiva), usually under 2 cm in size. Radiographs generally show no bony changes. Histologically the lesion is a non‐encapsulated, well-circumscribed myxoid (loosely collagenous) stroma populated by spindle‐shaped fibroblasts embedded in abundant hyaluronic acid–rich mucin. The pathogenesis remains unclear, though local trauma or irritation has been postulated to trigger fibroblast overproduction of hyaluronic acid. Complete surgical excision is curative and recurrences are exceedingly rare. In this case report, a case of oral focal mucinosis diagnosed in a 13-year-old girl is presented with its clinical, radiographic, and histological findings.
