Pathology
Histological report
Translation from Italian to English: nidus to be formed by osteoid tissue and newly formed bone trabeculae, immersed in a fibrous tissue, rich in vessels. The perifocal reaction zone is characterized by thickening and sclerosis phenomena with thickened bone trabeculae associated with edema of the loose connective tissue. Proceeding to the examination of the furthest layers of the cancellous bone it is observed that the trabeculae have normal dimensions and disposition, but the medulla is fibroadipose, with notes of edema and does not show any trace of hematopoietic tissue. Histological diagnosis: Osteoid osteoma.
