Abstract
Oral focal mucinosis (OFM) is an uncommon, asymptomatic, submucosal, slow-growing nodule representing a counterpart of the cutaneous focal mucinosis (CFM). OFM has a female predilection with the highest prevalence in the fifth decade of life. About 68% of OFMs occur in the gingiva and 14% in the palate. We present the case of a 41-year-old woman presenting a progressively growing mass on the palate, since the last 8 months. The diagnostic workup led to the diagnosis of an unusual OFM with the clinical presentation involving the gingiva and hard palate. This case report discusses the clinical and histopathological differential diagnosis.
Highlights
Oral focal mucinosis (OFM) is an uncommon, submucosal, tumor-like mass, and a counterpart of cutaneous focal mucinosis (CFM).[1]
OFM presents as a local gingival overgrowth, with fibroma, gingival epulis, pyogenic granuloma, and oral mucocele as the relevant differential diagnosis.[1,8,9]
A significant part of the lesion seemed to be correlated to the gingiva, which could support reactive injuries
