Abstract

Purpose: To report a rare case of intraosseous lipoma of the mandible and to discuss the most important features of the lesion, emphasizing the diagnostic pitfall that this entity may represent for general dentists and radiologists. Case description: An 18-year-old male patient presented an asymptomatic radiolucent lesion in the mandible in the region of the teeth 43 and 44 with no clinical alteration. After the incisional biopsy the histopathological exam revealed a capsulated lesion predominantly composed of mature adipose tissue and some areas of dystrophic calcification confirming the diagnosis of intraosseous lipoma. The lesion was surgically removed and no signs of recurrence could be observed after six months of follow-up. Conclusion: Due to the unspecific clinical and radiographic features and its rarity the intraosseous lipoma of the mandible may be a diagnostic challenge for general dentists and radiologists. Therefore, the histopathological examination is required for the correct diagnosis of the lesion.
