Abstract
Benign osteoblastoma refers to a benign tumor of the bone. Osteoblastoma most commonly affects the vertebrae and long tubular bones, however, in rare cases is observed in the facial bones. The current study presents the case of a 12-year-old female patient with a tumor in the mandibular body. Radiological imaging revealed a lesion with regular contours. The lesion was radically resected and histological analysis of the specimen demonstrated features that are typical of a benign osteoblastoma. The consequential defects of the jaw were reconstructed using titanium implants and autologous bone transplantation. The patient remains disease free subsequent to a five-month follow-up period. The aim of the present report is to present a rare case of benign osteoblastoma of the mandible. This study demonstrated that correct diagnosis and complete surgical excision are important to reduce the risk of recurrence of a benign osteoblastoma.
Highlights
Benign osteoblastoma is an osteoid and bone‐forming benign tumor that rarely occurs in the facial bones and was first described by Jaffe and Mayer in 1932 [1]
Osteoblastoma can be classified into two major clinicopathological forms as follows: The benign form, which has a slow growth rate, a well‐defined sclerotic margin and is moderately well vascularized with a mild inflammatory response; and the aggressive form, which exhibits locally aggressive behavior with a tendency to recur, often complicating its differentiation from low‐grade osteosarcoma [9]
The current study reports a rare case of benign osteoblastoma in a 12‐year‐old female patient, involving the right mandible, which was treated by surgical excision
Summary
Sedano in 1967 [7]. Subsequent data has revealed that the mandibular bones of the jaw are more commonly affected by osteoblastoma than the maxillary bones, with the majority of osteoblastoma affecting the mandibular posterior region [8]. The current study reports a rare case of benign osteoblastoma in a 12‐year‐old female patient, involving the right mandible, which was treated by surgical excision. A clinical examination revealed the presence of a firm, palpable tumor mass, the majority of which was situated within the body of the right mandible. The patient was subjected to a right lower jaw partial resection and the lesion was completely surgically removed (Fig. 2A‐C). It was noted that the lesion had not extended to the resection margin, indicating the complete removal of the tumor This is supported by continued patient follow‐up, with the patient feeling generally healthy and radiograph images indicating no signs of recurrence or complication five months subsequent to the surgery (Fig. 6)
