Mandibular Thinning Due to Peripheral Hemangioma: A Case Report

Background: Peripheral hemangioma is a benign congenital lesion and when involving the tongue, it does not appear on panoramic radiography. Case Presentation: This case report describes a 29-year-old male patient with peripheral hemangioma in his tongue and left side of the lower lip. In panoramic radiography, some calcifications are seen. In cone beam computed tomography (CBCT), more calcifications (phleboliths) and mandibular thinning are seen and if the lesion is not excised, it can result in mandibular fracture. As is known, biopsy or surgical excision of this lesion can result in severe hemorrhage, leading even to death. Therefore, accurate clinical and radiographic diagnosis is essential before starting any surgical intervention. Conclusions: Exact evaluation of panoramic radiographs by dentists is important for the detection of silent lesions. With early detection of these lesions, many side effects can be prevented. On the other hand, sometimes peripheral lesions, such as peripheral hemangiomas, affect adjacent bone in a way that mimics a central lesion and are difficult to distinguish using only two-dimensional images such as panoramic radiographs. Therefore, using complementary imaging techniques such as CBCT scans can help us better understand the extent of the lesion and its effects on adjacent structures.
