A psammoma body is a round collection of calcium, seen microscopically. The term is derived from the Greek word psammos meaning "sand."

Etiology

Psammoma bodies are associated with the papillary (nipple-like) histomorphology and are thought to arise from (1) the infarction and calcification of papillae tips and (2) calcification of intralymphatic tumor thrombi.^[1]

Association with lesions

Look up papillary in Wiktionary, the free dictionary.

Psammoma bodies are commonly seen in certain tumors such as:

Papillary thyroid carcinoma
Papillary renal cell carcinoma
Ovarian papillary serous cystadenocarcinoma^[2]
Endometrial adenocarcinomas (Papillary serous carcinoma ~3%-4%)
Meningiomas, in the central nervous system^[3]
Peritoneal and Pleural Mesothelioma
Somatostatinoma (pancreas)^[4]
Prolactinoma of the pituitary ^[5]
Mesothelioma, in membranes that line body cavities

Benign lesions

Micrograph of a psammomatous melanotic schwannoma with a psammoma body, as may be seen in Carney complex. H&E stain.

Psammoma bodies may be seen in:

Endosalpingiosis^[6]
Psammomatous melanotic schwannoma
Melanocytic nevus^[7]

Appearance

Psammoma bodies usually have a laminar appearance, are circular, acellular and basophilic.
