Unusual skull tumors with psammomatoid bodies: a diagnostic challenge

Clinical Neuropathology, 2017
We describe a series of three diagnostically challenging, histologically similar fibro-osseous skull masses.The cases were identified in our archives among 50,000 neuropathology specimens. A comprehensive review of the histological, immunohistochemical, ultrastructural, and imaging features as well as the clinical outcome was performed.The routine ...

Psammomatoid ossifying fibroma of the orbit is a distinctive solitary fibro-osseous lesion of the orbital bones that histologically has characteristic small, round structures resembling psammoma bodies within a benign spindle cell stroma. We describe a 19-year-old woman with this uncommon orbital tumour.

Psammomatoid juvenile ossifying fibroma: case study and a review

Oral and Maxillofacial Surgery, 2013
The group of fibro-osseous lesions from the maxillofacial region is very heterogeneous, but what they all have in common is the substitution of normal bone by fibroblasts with the consequent formation of collagen fibers, as well as substitution by different types of mineralized tissues which may be similar to bone or cement.

Psammomatoid ossifying fibroma of the ethmoid.

Bulletin de la Societe belge d'ophtalmologie, 2003
We present a 16 year-old girl who suffered since one year of a painless slow growing mass on the left medial orbital rim causing globe displacement. CT-scan and MRI of the orbit with T1 and T2 weighted images showed the presence of a large mucocoele in the frontal sinus. This occurred secondary to the obstruction of the sinonasal tract by a bony tumour.
