The authors introduce a 42-year-old woman with a choroidal osteoma. After 10 years the patient presented a second choroidal osteoma in the same eye; this osteoma has been growing in the last years. New tests that were unavailable during the first diagnosis were performed such as Fundus Autofluorescence or Enhanced Depth Imaging-Optical Coherence Tomography (EDI-OCT). These tests show characteri...

Frontal sinus osteomas are mostly asymptomatic and slow-growing benign tumors most frequently involving the frontal sinus [1]. The surgical procedures available for osteoma removal can be classified into external, endoscopic, or a combination of both [2]. The external approach is often selected to ensure complete and safe removal of frontal sinus osteoma located close to both orbits [3]. Here, ...

The osteoma is a benign osteogenic neoplasm of bone. Peripheral osteoma of the mandible is uncommon. It is often asymptomatic and usually discovered when a patient complains of esthetic problems and presents for treatment. Peripheral osteomas have a characteristic clinical and radiographic appearance, but their pathogenesis is obscure. Described here are two patients with peripheral osteoma of ...

Osteoid osteoma is a benign osteoblastic tumor that is unusual in the hand. A location in the carpal bones is infrequent, which leads to errors in diagnosing it because of polymorphism of the clinical symptoms. Reviewing the literature shows that nine cases of osteoid osteoma in the scaphoid have been reported. Here, one case of osteoid osteoma in the scaphoid that was initially treated as De Q...

Osteoma of the temporal bone most commonly occurs in the external ear. Osteomas in the middle ear are not common, and only 25 relevant cases (18 papers) have been reported in the English literature. With only 5 cases reported to date, osteoma of the promontory in the middle ear is rare. This study reports a case of asymptomatic osteoma of the promontory in the middle ear mimicking a congenital ...

Osteoma is the most common benign tumor of the paranasal sinuses. Turbinate osteomas are very rare and only four middle turbinate, one superior turbinate and one inferior turbinate osteoma cases have been reported. We present a rare case of osteoma of the left middle turbinate in a patient presented with unilateral nasal obstruction and epiphora that was removed endoscopically, and conduct a li...

In case of intra-articular osteoid osteoma, misdiagnosis as juvenile arthritis may occur, delaying adequate treatment. We report cases of intra-articular osteoid osteomas in children that were misdiagnosed and initially inappropriately treated with intra-articular corticoid injection. Diagnosis of osteoid osteoma was finally given by CT-scan and appropriate treatment by radiofrequency ablation ...

We present a case of osteoid osteoma with a history of mild pain, local swelling and point tenderness on the right lower leg. The diagnosis of osteoid osteoma was difficult due to the atypical clinical history and misleading radiological and bone scan findings. When it is difficult to differentiate an osteoid osteoma from osteomyelitis using CT, MRI or bone scan; HIG scintigraphy can be used to...

A long-term follow-up of three patients suffering from osteoid osteoma who have not undergone surgery is reported. Only eight similar cases have been reported in the literature. It is shown that over a period of years the pain of osteoid osteoma eventually disappears but the radiological appearance may remain unaltered or gradually resolve. Surgical management of osteoid osteoma is advised beca...

Osteoid osteoma is an uncommon benign tumor and causes severe pain, being worse at night, that responds dramatically to nonsteroidal anti-inflammatory medications. An osteoid osteoma of the toe is very rare and arising in a pedal phalanx may be difficult to diagnose. A 34-year-old male has local swelling and tenderness but there were no hyperemia, temperature increase, or clubbing. There was a ...
