Juvenile ossifying fibroma is a rare benign tumour of childhood. It is hardly distinguishable from others fibro-osseous lesions because of their overlapping microscopic features. Juvenile variant of ossifying fibroma may be mistaken for malignancy, particularly osteosarcoma. Radiology is central to their diagnosis because of the very limited nature of the tumour. Microscopically, the lack of cytologic atypia or abnormal mitosis, and the presence of bone maturation or cementum deposits are consistent with an ossifying fibroma. This entity should be kept in mind regarding any bone lesion jaws in children.

Papillary meningioma (MP) is a rare and aggressive variant of meningioma, occurring preferentially in young subjects. Histopathological features of papillary meningiomas are characterized by papillary or perivascular pseudorosette patterns. We report the case of a right frontal MP in a 16-year-old boy. Differential diagnosis included other primitive or secondary intracranial papillary neoplasms. MP diagnosis should not be missed due to its aggressive behavior with brain invasion, local recurrence and metastases.
