源发于鼻腔的嗅神经母细胞瘤甚为少见。1942年Berger等首次报导,至1979年世界文献中仅报导160多例。国內报导始见于1964年,迄今不过20余例。我们最近遇到3例,其中例3的肿瘤穿破筛骨及眼眶,主要向颅内生长而误认为颅内肿瘤。兹报导如下。 Origin of the nasal olfactory neuroblastoma is rare. Berger et al. First reported in 1942 that only 160 cases were reported in the world literature in 1979. Domestic reports first appeared in 1964, but so far more than 20 cases. We recently encountered three cases, of which the tumor of Example 3 was broken through the ethmoid bone and the orbit, mainly to intracranial growth and mistaken for intracranial tumors. It is reported below.
