| ICD-10 online (WHO version 2019) | |
The osteoblastoma belongs to the group of primary bone tumors . This new formation emanating from the osteoblasts is always benign. Morphologically it is very similar to the osteoid osteoma .
pathology
The osteoblastoma is the "big brother" of the osteoid osteoma , but has no self-limiting growth in size. It occurs primarily in the spine and long tubular bones. Its maximum age is between 10-20. Years of age, with boys being affected twice as often as girls. David Dahlin referred to the osteoblastoma as Giant osteoid osteoma in 1954 . Henry Lewis Jaffe identified his entity .
In X-rays , a central lightening zone having a diameter greater than 2 cm in contrast to the osteoid osteoma shows. There is usually no sclerosis in the area . Histologically, the osteoblastoma consists of wide osteoid trabeculae with osteoblasts and osteoclasts numerous capillaries .
diagnosis
The diagnosis can be made radiologically (localization more often in the spine (40%)). In contrast to the osteoid osteoma, osteoblastoma is less likely to cause night pain.
therapy
Therapy consists of either a complete removal (curettage) or partial removal (segment resection) of the bone.
forecast
The prognosis is very favorable. Even if the entire tumor is not removed, healing can definitely be expected.
