Infantile olfactory neuroblastoma. A clinicopathological study with review of the literature

A case of olfactory neuroblastoma occurring in a 3-year-old girl is reported. The rarity of the lesion in early childhood is stressed and discussed with the clinico-pathological characteristics of the tumour, which are apparently more aggressive the younger the patient. Olfactory neuroblastoma should be considered as a possible diagnosis regardless of the age of the patient.
