In osteoid osteomas, the nidi are smaller than 1.5cm in diameter and are often surrounded by a ring of sclerotic bone tissue.

在骨样骨瘤中，癌巢直径通常小于1.5cm，并且通常被硬化的骨组织包围（边缘硬化）。

Those crystals then act as a nidus, or place where more solutes can deposit and over time it builds up a crystalline structure.

然后这些晶体作为一个“巢”，越来越多的溶质将会在此累积，随着时间的推移，逐渐构建成一个晶体结构。

Both of these tumors classically form a nidus – which is a disorganized mix of small blood vessels, tiny rods of bone called trabeculae, and unmineralized bony tissue called osteoid.

通常这两种肿瘤形成癌巢：癌巢是小血管、小棒状骨（小梁骨）、未矿化骨（即类骨质）等无组织的构成。
