Abstract
The present study aimed to add to the literature a challenging case of an asymptomatic lesion showing a radiolucent aspect at the mandible mimicking a residual cyst. A 60-year-old woman presented a mandibular lesion, detecting during the imaging exams. Computed Tomography revealed a hypodense lesion with a sclerotic margin measuring about 0.8 x 0.8 x 0.7 cm on the right posterior mandible. The main differential diagnosis was a residual cyst, and an excisional biopsy was performed.Microscopic analysis revealed papillary projections and thrombi within the lumen of the vessel lined with endothelial. Immunohistochemical analysis was positive for CD34 and smooth muscle actin. Based on these findings, the lesion was identified as intraosseous intravascular papillary endothelial hyperplasia.This case report provides information about this potential hypothesis of unilocular radiolucency located in the jawbones.
