Osteoid osteoma transformation into osteoblastoma: Fact or fiction?

Osteoid osteoma transformation into osteoblastoma: fact or fiction?

BACKGROUND Osteoid osteoma and osteoblastoma are rare, benign, bone-forming tumours. The clinical presentation, imaging study findings, and course indicate clearly that these two tumours are distinct entities. CLINICAL REPORTS We report two cases suggesting transformation of osteoid osteoma into osteoblastoma and therefore inviting a discussion of the links between these two tumours. An 11-ye...

Osteoid osteoma and osteoblastoma.

Osteoid osteoma and osteoblastoma are commonly seen benign osteogenic bone neoplasms. Both tumors are typically seen in the second decade of life, with a notable predilection in males. Histologically, these tumors resemble each other, with characteristically increased osteoid tissue formation surrounded by vascular fibrous stroma and perilesional sclerosis. However, osteoblastomas are larger th...

Osteoid osteoma and benign osteoblastoma in childhood.

Three cases of osteoid osteoma and one of benign osteoblastoma in children are described. The main complaint was severe pain which was worse at night; it was relieved by aspirin or other analgesics. The diagnosis was made on clinical and radiological grounds and was confirmed on histological examination of the central nidus removed at operation. The pain was relieved in the patients with osteoi...

Sonofusion – Fact or Fiction?

Sonoluminescence and Sonofusion phenomena may occur when vapor bubbles implode. This paper reviews the status of our understanding of the bubble dynamics involved in these interesting phenomena. In particular, the experimental and analytical evidence supporting the observed production of neutrons and tritium due to thermonuclear fusion within imploding bubble clusters is reviewed. Moreover, pot...
