Osteoid osteoid, cortical iso-osteoid, sclerosing osteitis
English: osteoid osteoma
An osteoid osteoma is a benign tumor change in the skeleton.
X-rays typically show local bone compression in the area of the hard tubular bone with a central cavity (nidus). Nocturnal pain that responds well to aspirin is typically described.
The osteoid osteoma is the third most common benign bone change in adolescence after the non-ossifying fibrioma (NOF) and the osteoma.
Boys are particularly affected by this tumor.
It occurs particularly frequently in the upper part of the thigh bone, but also more frequently in the tibia (shinbone) and in the spine. All other bones (finger bones) can also be affected.
Night pain is typical and so is the immediate relief of pain with aspirin therapy (ASA).
In the center there is nidus (circled in red), in the nidus cavity often hypervascularized (increased blood supply). Surrounding reaction: hyperostosis (increased bone formation) with often pronounced asymmetrical bone thickening.

The osteoid osteoma occurs predominantly in males (M> W 3: 1).
The osteoid osteoma represents 14% of all bone tumors.
The tumor usually occurs between the ages of 10 and 20; it can occur before the age of 10 and very rarely after the age of 30.
Occurrence:
The origin of the osteoid osteoma are still unclear today.
The osteoid osteoma is benign and therefore does not metastasize.
Alternative diagnoses to consider:
There are no clear symptoms that indicate an osteoid osteoma:
1. Imaging diagnostics:
2. Pathology:
In the fine tissue examination under the microscope one finds very well perfused connective tissue, which is surrounded by a sclerotic bone. Of the
3. Serum / blood test:
The tumor does not cause any changes in the blood.
In order to achieve freedom from symptoms, the tumor must be removed as a whole (en bloc resection), since it can form again if the residual tissue is left behind (relapse)

There are different forms of bone cancer.
