“…1,14 Even though our case exhibited aggressive growth of the recurrent lesion, there was no epitheloid osteoblast and cellular atypia in the second surgical specimen on histopathological examination. Ataoglu et al 5 and Colm et al 6 made similar observations in a case of recurrent osteoblastoma of the mandible.…”

“…On very rare occasions, however, these tumours may demonstrate progressive growth, local recurrence and, less frequently, malignant transformation. [1][2][3][4][5][6] Although the first case of benign osteobalstoma of the maxilla was reported back in 1967, 7 unfortunately most of the reported cases lacked a comprehensive description of the imaging findings. Previous studies reported 3,4,[7][8][9][10][11][12][13][14][15] that generally the lesion had well-defined borders and might have a completely radiolucent appearance, or it might show radiolucencies and radio-opacities.…”

“…Others reported that the aggressive behaviour in osteoblastoma was multifactorial. 5 Tumour location and complete removal with wide safety margins are important clinical factors. In the present case, the initial misdiagnosis of the lesion prompted the surgeon to go for a rather conservative approach.…”

Osteoblastoma is a benign neoplasm which commonly occurs in the vertebral column and long bones. The tumour grows slowly and rarely recurs after surgery. This report presents the clinicopathological and radiological findings of a case of recurrent osteoblastoma in the maxilla. A 7-year-old male patient visited our department with chief complaints of left facial swelling and pain. A panoramic radiograph showed a homogeneous radio-opaque expansile lesion in the left maxilla. The lesion was thought to be fibrous dysplasia and the patient underwent a surgical excision using the Caldwell-Luc procedure. Histopathological examination of the lesion confirmed it as benign osteoblastoma. The lesion recurred 6 months after the initial surgery. CT images revealed a large mass with multiple internal calcifications. Subsequently, the patient underwent mass excision with subtotal left maxillectomy. Follow-up CT scans at 1 year intervals showed no recurrence for 5 years. Dentomaxillofacial Radiology ( Keywords: osteoblastoma; recurrence; X-ray computed tomography Case reportA 7-year-old male patient visited our department with the chief complaints of left facial swelling and pain. His medical history was unremarkable. Clinical and radiographic examinations were performed. Intraoral examination revealed a firm gingivobuccal swelling extending from the left maxillary deciduous lateral incisor to the left maxillary permanent first molar. Panoramic radiographs showed a homogeneous radio-opaque expansile lesion in the left maxilla and the lesion involved the whole maxilla. The adjacent tooth germs were displaced and the innominate line in the left maxillary sinus was not detected (Figure 1). The lesion was thought to be fibrous dysplasia from the initial clinical and panoramic radiographic findings; therefore, mass excision using the Caldwell-Luc operation was performed. The surgical specimen was 3.5 cm in diameter and it was spherical, encapsulated and firm tissue. On histopathological examination, bony trabeculae surrounded by a single layer of plump osteoblasts of high cellularity were observed in the stroma. There was no atypia or mitotic activity in the osteoblasts or in the mesenchymal cells of the stroma. Most of the calcifications consisted of woven bone without obvious lamellation. Multinuclear giant cells were often identified around the osteoid. As the trabeculation progressed, the stroma changed into loose fibrovascular tissue. The lesion was finally diagnosed as benign osteoblastoma (Figure 2).The patient revisited our department with an enlarged swelling in the same region 6 months after the operation. CT images revealed a large well-defined mass composed of two locules with multiple internal calcifications. Owing to the expansive nature of the lesion, the left orbital floor was elevated and the lateral wall of the left nasal cavity was pushed towards the medial side (Figure 3). The patient had undergone mass excision with subtotal left maxillectomy. The surgical specimens were composed of two, solid, firm soft-tissue ...

“…However, recurrences of the lesions, when described in the literature, were related to the difficulty of access, facilitating incomplete approaches 22,23 or even inadequate initial treatment due to incorrect preoperative diagnosis 11 . Therefore, the possibility of recurrence would be more related to these factors than to the pathological behavior of osteoblastoma.…”

Osteoblastoma is a rare benign bone tumor that accounts for less than 1% of all primary bone tumors. Due to a low occurrence and varied histopathological aspects, this pathology becomes a diagnostic challenge. Therefore, our objective of reporting a case of osteoblastoma in the maxilla is to discuss another presentation of this tumor. Male patient, suffering from leucoderma, 50 years old, presented an expansion in right superior vestibular groove with pain during palpation and an extensive osteolytic lesion in the right maxilla, of solid content, observed in computed tomography. With an anatomopathological diagnosis of osteoblastoma by an incisional biopsy, conservative surgery was performed to remove the lesion. The definitive analysis of the excised tumor confirmed the preoperative diagnosis. The patient has been followed up for a period of 5 years without relapses of the neoplasia. Therefore, due to the rarity and the difficult diagnosis, describing cases like this one and their presentation characteristics is extremely important to enhance knowledge of this pathology among professionals in the area of diagnosis and maxillofacial surgery.

Osteoblastoma is a rare benign neoplasm formed by osteoid tissue and well-vascularized bone that occurs mainly in children and adolescents. It appears primarily in the long bones, vertebral column, and small bones of the hands and feet, and not typically in the skull and maxillary bones. The purpose of this study is to present the case of an 8-year-old girl with a diagnosis of right mandibular osteoblastoma and a review of the relevant literature. The goals of treatment were to preserve dental occlusion, masticatory function and facial symmetry while minimizing the effects on patient body image and quality of life. Osteoblastoma, although it is benign, can be aggressive, and its treatment will depend on the timing of diagnosis, size and location. Early diagnosis is essential to avoid not only radical surgery as in the case presented, but also to help minimize the risk of possible relapse and potential malignancy of a benign osteoblastoma.
