[The psammo-osteoid fibroma of the maxilla].
A case of a rare subtype of midfacial ossifying fibroma in a 5-year old child is presented. Fibro-osseous lesions represent a variety of bone proliferations each characterised by different morphological patterns of osteoid production. Psammomatoid ossifying fibroma is characterised histologically by numerous small round ossicles resembling psammoma bodies and is a locally invasive lesion of facial and cranial bones. The histopathology is described. The surgical treatment includes complete resection of the tumour as well as involved bones by means of midfacial degloving. Two years after surgical treatment the child is free from symptoms and tumour recurrence.
