Psammoma bodies

Psammoma bodies are microscopic, rounded structures commonly found in some types of tumours. These bodies are characterized by concentric layers of calcium and proteins, giving them a lamellated or onion-like appearance under a microscope. The term “psammoma” is derived from the Greek words “psammos,” meaning sand, and “oma,” meaning tumour.

Psammoma bodies are commonly associated with tumours that show a papillary pattern of growth. In pathology, papillary refers to a finger-like projection of tissue with tumour cells lining the outside surface of the tissue.
