Psammoma bodies in serous carcinoma. H&E stain.
Psammoma bodies in meningioma. H&E stain.

Psammoma bodies appear in benign and malignant conditions. Their presence can help focus the DDx.[1]

They are often associated with a papillary architecture.[citation needed]

Conditions with psammoma bodies

The following is an incomplete list.

Benign

Malignant

Memory device PSaMMoma: Papillary (thyroid, renal), Serous (ovary), Meningioma, Mesothelioma.[8]

Isolated psammoma bodies in smears or aspirates are an unreliable predictor of papillary carcinoma. [9]
