The tumors of the external auditory canal are relatively rare. Among these tumors an osteoma is not common. Two cases of osteoma of the external auditory canal were reported. The patient, 26-year-old female, had a history of left-sided hearing impairment and w hard mass protruding from the posterior part of the left external canal. A stony hard mass almost completely occlu ded the left external...

We report the molecular cloning of two replication-competent osteoma-inducing murine leukemia viruses from the RFB osteoma virus stock (M. P. Finkel, C. A. Reilly, Jr., B. O. Biskis, and I. L. Greco, p. 353-366, in C. H. G. Price and F. G. M. Ross, ed., Bone--Certain Aspects of Neoplasia, 1973). Like the original RFB osteoma virus stock, viruses derived from the molecular RFB clones induced mul...

Osteoma is a dense bony proliferation of otherwise normal membranous bone. This tumor is essentially restricted to the craniofacial skeleton and is rarely diagnosed in other bones. The mandible and the paranasal sinuses are the most common sites, while the involvement of the coronoid process has been reported in only 6 cases so far. This report demonstrated a case of osteoma occurring at the ma...

Osteoma is a benign, slowly growing tumor that mainly occurs in the bones and cavities of the middle third of the face, representing the most frequent benign tumor of the paranasal sinuses. It rarely originates primarily from the orbit. Most of these lesions develop in the fourth to fifth decades of life, and are more commonly encountered in males. In the English literature, there are so far th...

Osteoid osteoma is a benign bone tumor that when located on the base of the coracoids process of the scapula is very rare and diagnosis and treatment is often delayed because of its rarity. Almost any bone can be involved, but half of cases involve the femur or tibia. The radiologic features of osteoid osteoma are well known, but these tumors may present with unusual features and be easily misd...

BACKGROUND Osteoid osteoma accounts for approximately 10% of all benign bone tumors. The most common sites of osteoid osteoma are the subcortical shaft and metaphyses of long bones, but any other skeletal bone site can be involved. The acetabulum is a rare site according to past reports. This site presents challenges to optimal management because it is anatomically difficult to approach, and be...

Osteoma is a slowly growing, asymptomatic, benign osteogenic tumor. An extremely rare case of clavicular parosteal osteoma (PO) reported. A 46-year-old female patient was treated with marginal resection after an open biopsy for large, firm symptomatic mass originating from the middle part left clavicle, which recurred 25 years surgery. In fifth year postoperatively, followed up full range motio...

RATIONALE Lumbar osteoid osteoma has a low incidence, which could easily lead to scoliosis. PATIENT CONCERNS Scoliosis secondary to lumbar osteoid osteoma could be easily misdiagnosed when patients do not complain of obvious symptoms. DIAGNOSES We reported a case of a 9-year-old boy with back deformity that was firstly diagnosed with scoliosis at the local hospital. After prescribed with or...
