Pediatric Tumors of the Central Nervous System: Cytopathology, posterior fossa is high in children, accounting for approximately 30% of all CNS neoplasms . In the pediatric population, tumors frequently arise in midline structures, including optic chiasm, suprasellar region, cerebellar vermis, brainstem, thalamus, and pineal region. Histologically, pediatri

Blastemal Tumors,tous component (small blue cells tumors) or inversely may contain differentiating blastematous component. This component may mature to epithelial cells (renal tubes in nephroblastoma), neuronal patterns (neuroblastoma), skeletal tissue (pleuropulmonary blastoma), or muscular tissue (nephroblastomas), etc.

Low-Grade Superficial Connective Tumors,ions are schwannomas, desmoids, and “pseudosarcomatous lesions” such as nodular fasciitis. Experience of FNA of angiomatoid fibrous histiocytoma (AFH), fibrous hamartoma of infancy (FHI) and some other rare soft tissue lesions is limited, at most based on single cases or short series.

Miscellaneous Epithelial and Epithelial-like Tumors,erential diagnoses, may be different. Due to their infrequency and sometimes morphologic similarity to more common round cell tumors, they are not always considered as differential diagnostic possibilities. Thyroid lesions will be considered in a separate chapter due to their importance in childhood pathology.
