Lipoma in Oral Mucosa: Two Case Reports

Lipoma is a common tumor of soft tissue. Its location on the oral mucosa is rare, representing 1% to 5% of benign oral tumors although it is the most mesenchymal tumor of the trunk and proximal portionsof extremities. Lipoma of the oral cavity may occur in any region. The buccal mucosa, tongue,and floor of the mouth are among the common locations. The clinical presentation is typically as anasymptomatic yellowish mass. The overlying epithelium is intact, and superficial blood vessels areusually evident over the tumor. Other benign connective tissue lesions such as granular cell tumor,neurofibroma, traumatic fibroma and salivary gland lesions (mucocele and mixed tumor) might beincluded in differential diagnosis. We present two cases of oral lipoma in unusual locations: one injunction of soft and hard palate and the other in tongue. Both were rare in the literature.
