Surgical curettage or en bloc excision are the usual choice of treatment for osteoma. Local recurrence of osteoma after surgical treatment is not very common. We report a case of osteoma recurred at the grafted bone. A $5{\times}8cm$ sized osteoma of frontal bone was excised and then the defect was covered with calvarian bone and rib bone. Six years after reconstruction, recurrence from grafted area was noted. We completely removed the osteoma with enough normal tissue around it, after checking that the grafted bone has changed into an osteoma through a bicoronal incision. Then we covered the defect with a rib bone. The tissue was confirmed histologically as an osteoma. The recurrence of the tumor at the bone grafted site after osteoma excision is probably due to the fact that we covered grafted bone with periosteum left over osteoma. Therefore, we can learn that when we excise osteoma, galea should be carefully separated from the periphery of the tumor and that the periosteum should be completely removed, to prevent the osteoma from recurrence.

Osteoma is one of the benign tumor that occurs on the bones all over the body. Mostly the simple excision is known to be enough. However, sometimes we encounter the troublesome situation where the osteoma is located in very challenging area, which results in the recurrence. 26 year female presented with the intractable intracranial osteoma. Given the disease entity of the osteoma, the simple excision would be enough or conservative management. But this osteoma turned out to be huge and recurrent in spite of the endoscopic resections, which causes the facial disappearance accompanied by the orbital vertical dystopia. Moreover, the patient's main concern was the pain. We performed the intracranial resection of the whole lesion and reconstructed the skull base and frontal bone as well as the part of the orbital wall. In order to restore the original bony anatomy, the 3D printing model was used based on the titanium mesh. I report this unusual case of the intractable intracranial huge osteoma. This report may be helpful for the other surgeons to make a decision on their similar cases in the future.

Osteoma is benign tumor composed of mature compact or cancellous bone. Generally it is classified as periosteal(or peripheral) osteoma and endosteal(or central) osteoma by its origin. Clinically, periosteal osteoma on forehead is usually asymptomatic. From March 2002 to February 2005, We experienced 20 patients(23 cases) of histologically confirmed frontal osteoma. 20 patients are classified as sex, age, the number of osteoma, size, location and shape. Out of 20 patients, 16 were female and 4 were male in sex and mean age was 46. 18 patients have only one lesion but one patient has two lesions and another patient has three lesions. The size of osteoma varied from $7{\times}5{\times}3mm$ to $16{\times}14{\times}6mm$ and mean size is $12{\times}10{\times}5mm$. All osteomas were located at midline of forehead and shape of attachment was all sessile type. Surgical excision was superficial ostectomy through direct cutaneous incision or endoscopic approach. we obtained satisfactory result without specific complication.

Osteoma is a slow growing benign osteogenic lesion characterized by proliferation of compact or cancellous bone. Osteomas may be classified as peripheral, central, or extraskeletal. Central osteoma arise from the endosteum, pheripheral osteoma from the periosteum, and extraskeletal soft tissue osteoma within a muscle. Peripheral osteoma of the mandible is uncommon. They manifest as asymptomatic, fixed tumors of bony-hard consistency that may be sessile or pedunculated. Radiographically, a well circumscribed round or oval radiopaque mass is seen. Here, we report a case of a huge solitary peripheral osteoma of the buccal posterior mandible in a 40-year-old woman who was otherwise in good health. The patient visited at the dental clinic because the lesion makes esthetic problem. Treatment was performed by surgical esthetic recontouring and histological examination. The patient remains free of recurrence after surgical esthetic recontouring operation.

Osteomas are uncommon benign turners, occasionally located in the paranasal sinuses, of which the frontal and ethmoid sinus is the most frequent site. The etiology of the osteoma is still unknown but three possible theories have been proposed; embryological, traumatic and infective. The most common symptoms of osteoma are facial pain and headache, but most of them are asymptomatic and discovered incidentally on routine sinus radiography. Recently, the authors experienced two cases of large osteoma of the ethmoid sinus that were removed successfully by external ethmoidectomy.

Osteoid osteoma, a frequent lesions of bone, is usually intraosseous but occasionally subperiosteal. We describe the case of a 19-year-old male with knee pain caused by subperiosteal osteoid osteoma. Radiologic evaluation was performed with radiographic, computed tomography (CT), ultrasonographic (US) and magnetic resonance imaging (MRI). But the preoperative diagnosis of osteoid osteoma was delayed because of unusual imaging findings and atypical symptom. After excisional biopsy, histological examination confirmed the diagnosis of osteoid osteoma. The lesion was treated successfully with CT-guided radiofrequency ablation.

Osteomas are benign osteoblastic tumors that occur mainly in the fronto-ethmoid areas ofthe head and neck region. When they occasionally occur in the temporal bone, the external auditory canal is the most common site of origin; they rarely occur in the mastoid region. Moreover, mastoid osteoma with mastoiditis is an extremely rare entity in the temporal bone. Recently, the authors experienced a case of mastoid osteoma with mastoiditis in the left temporal bone. The mastoid osteoma was completely resected itself without a mastoidectomy, only for correction of the cosmetic deformity; the mastoiditis was not treated. Hence, the authors report the first case of a mastoid osteoma with mastoiditis in Korea, along with a review of the related literature.

An intra-articular osteoid osteoma is a very rare cause of elbow pain, and its diagnosis and treatment remain challenging. Delayed diagnosis may lead to arthritic change of the joint. In this study, the authors present the occurrence of intra-articular osteoid osteoma in the right elbow of a 15-year-old male patient who presented with prolonged pain and limited motion owing to delayed diagnosis. After confirming the nidus of osteoid osteoma from radiographic evaluation, the lesion was completely removed arthroscopically. The patient presented a complete relief of symptoms and full range of motion. This is the first domestic report of successful arthroscopic treatment of an intra-articular osteoid osteoma of the elbow.

A 65-year-old woman presented with a solid mass on the right temporal area. The mass had grown for over 2 years without any initiating event of trauma or inflammation. Before excision, the patient went through a computed tomography scan, revealing a calcified mass without bony connection. Under general anesthesia, an excisional biopsy was performed. Microscopic examination confirmed a diagnosis of soft tissue osteoma. Soft tissue osteoma is rare, especially in the head and neck region. Osteomas in the temporal region have not been reported yet. Due to its rarity, osteoma might be misdiagnosed as another soft tissue or bone origin tumor. Its treatment of choice is simple excision. In this review, we present an unusual clinical form of soft tissue osteoma.

Osteoid osteoma is a benign bone tumor composed of osteoid and atypical bone. The most commonly known sites of following tumor are long tubular bones, especially femur and tibia. Yet, development of osteoid osteoma in the foot is unusual, and there aren't much reported literatures of metatarsal osteoid osteoma. In this article, we report a case of the osteoid osteoma in the 3rd metatarsal bone of a 14-year-old male patient.
