Verocay body
Verocay Body
Verocay body (pronunciation: vɛrəkeɪ bɒdi) is a histological finding typically seen in schwannomas and neurofibromas, which are types of peripheral nerve sheath tumors.
Etymology
The term "Verocay body" is named after the Uruguayan pathologist Jose Verocay, who first described these structures in 1910.
Description
Verocay bodies are composed of two rows of Schwann cells with their nuclei aligned in a palisading pattern. Between these rows, there is a clear, acellular zone known as Antoni type A area. This pattern is characteristic of schwannomas, but can also be seen in other types of peripheral nerve sheath tumors.
