Three siblings (a sister and two identical-twin brothers) had bilateral choroidal osteomas. The sister was seen at 11 years of age, and the tumor showed significant growth two years later. The twin brothers' tumors were diagnosed at 9 years of age, and their conditions remained stable over two years except for a new, isolated lesion that occurred in one eye of one brother. The siblings' mother had a yellow mottling situated nasal to the disk in each eye that was similar in appearance to that in one eye of one of the twins. She showed no evidence of calcium on ultrasonography. The appearance of osteomas in three siblings suggests a choristoma as the cause of this tumor.

Temporal bone osteoma is an unusual pathology which can occur by birth or can be acquired and mostly involves the tympanomastoid segment of the temporal bone. Osteomas arising from the otic capsule are extremely rare, and there has been only one other report of a lateral semicircular canal osteoma in the literature. We report a similar case of an acquired lateral canal osteoma which presented as a chronic postaural fistula in an ear previously operated for paediatric cholesteatoma.

The use of MRI for the evaluation of lesions in the internal auditory canal presents a potential pitfall in the diagnosis of bony lesions of the IAC, because bone is poorly visualized with this method of imaging. The presence of marrow in an osteoma might aid in its detection, since fat in the marrow has a bright signal intensity of T1-weighted imaging. Computed tomography remains the imaging modality of choice for bony lesions of the temporal bone. We demonstrate a case of IAC osteoma in which surgical removal resulted in improvement of symptoms. The gross and microscopic appearance of the IAC osteoma in this case is similar to the characteristic findings of osteomas of the EAC. This suggests that the criteria applied to osteomas and exostoses of the EAC may also be used to differentiate bony lesions of the IAC.

A case of multiple miliary osteomas of the face in a 68-year-old female with no personal history of acne or former inflammatory skin disorders is reported. The patient showed multiple painless, stone-like formations at several sites of the face. Histological, echographic and radiological investigations confirmed the presence of bone tissue in the dermal layer. Multiple miliary osteoma of the face is considered the rarest variant of primary osteoma.

A 30-year-old woman developed proptosis secondary to a left ethmoidal compact osteoma. At age 29 years, a mandibular eburnated (ivory) osteoma was excised. At age 25 years, multiple adenomatous polyps of the colon were resected. Her father, age 61 years, had multiple intestinal polyps and bilateral mandibular osteoma. A 24-year-old sister had an osteoma of the forehead. Gardner's syndrome is an autosomal dominantly inherited disorder characterized by intestinal polyposis, various skin and soft tissue tumors, and osteomas of the bony skeleton. Orbital osteomas occur rarely.

Osteomas are benign, slow growing tumors of bone that occur almost exclusively in the craniofacial region. They are uncommon in the temporal bone. Surgical excision is indicated in symptomatic cases. An osteoma arising from the lateral semicircular canal growing into the mastoid cavity is extremely rare and usually discovered on routine radiography. We present a case of osteoma arising from the lateral semicircular canal growing into the mastoid cavity, followed by a discussion of the etiology, presentation, and management of osteomas.

Osteomas of the temporal bone are benign neoplasms that may be encountered by otolaryngologists. Clinically they should be distinguished from exostoses, which involve the external auditory meatus and are a well recognized entity. Osteomas involving the middle ear and ossicles are extremely rare. There is only one case report in the literature of an osteoma involving an ossicle and in that patient, who presented with conductive loss, the incus was involved. The present report presents a 48-year-old white male, who on routine examination was found to have a mass in his left tympanic membrane. Under local anesthesia the mass was totally excised, after it had been separated from the umbo. Histopathologic sections of the mass revealed a benign osteoma. A brief review of osteomas and exostoses of the temporal bone is presented.

Forehead osteomas are benign bone tumors. They are frequently associated with exophytic growth in the outer table of the skull, causing cosmetic disfigurement of the face. The objective of this study was to present the efficacy and feasibility of the endoscopic treatment of forehead osteomas by presenting a case report with details of the surgical technique. A 40-year-old female patient presented with aesthetic complains of a progressing bulge in the forehead. A computed tomography scan with 3-dimensional reconstruction showed bone lesions on the right side of the forehead. The patient underwent surgery under general anesthesia with no noticeable incision, which was planned 2 cm behind the hairline in the midline because the osteoma was close to the midline plane on the forehead (Video 1). A retractor coupled with a 4-mm channel for endoscopy and a 30-degree optic was used to dissect, elevate the pericranium, and locate the 2 bone lesions in the forehead. The lesions were removed using a chisel, endoscopic facelifting raspatory, and a 3-mm burr drill. The tumors were resected completely, resulting in good cosmetic outcomes. The endoscopic approach for treating forehead osteomas is less invasive and facilitates complete removal of tumors, which results in good cosmetic outcomes. Neurosurgeons should consider and add this feasible approach to enhance their surgical armamentarium.

We report the case of a 64-year-old male patient with a 5 month history of proptosis, motility limitation and vision loss in OD. Visual acuity (VA) was 20/200 in OD and 20/20 in OS. CT showed a large, round, intraconal lesion, with bony density and no apparent connection to adjacent orbital walls. MRI showed a T1-weighted hypointense lesion surrounded by a contrast enhancing capsule. The orbital tumor was excised through a lateral orbitotomy revealing a nodular, round, osseous structure. Histological examination disclosed well-formed lamellar bone trabeculae, with no necrosis or mitosis figures. Immunohistochemical staining was negative for MDM2 and CDK4. After 3 years, there was no evidence of tumor recurrence and VA had improved to 20/30. Intraconal osteomas with no clear attachment to orbital walls are extremely rare. We are aware of a few reported cases in the lid, hand, thigh, tongue, pterygopalatine fossa and brain. To the authors' knowledge, this is the first report in English literature of an orbital intraconal osteoma without any visible relation to the orbital walls.

Osteomas of the middle ear are rare benign tumors. They commonly arise from the promontory. To date, a total of three cases of osteomas of the ossicles, inseparable from malleus and incus, have been described in the English literature. Among them, only one case osteoma with congenital cholesteatoma has been reported. Recently a 6-year-old boy with osteoma associated with congenital cholesteatoma presented to our service. The osteoma and congenital cholesteatoma were removed successfully by canal wall up mastoidectomy with staging operation. A rock-hard mass was separated from the footplate. The malleus and short process of incus were intact. Histopathological examination confirmed the presence of the osteoma.
