Recently the authors have encountered a case of severe para-nasal sinusitis, 5 cases of early stage of carcinomata and a case of juvenile carcinoma occured in para-nasal sinus yet masked by prolonged chronic otitis media.
From these experiences, the authors emphasized the lessons they learned. Those are: once the histopathological diagnosis of tumor is established, clinicians should bring the case along with full clinical informations to pathologists for thorough discussion regarding the degree of malignancy, and it is the clinicians who should decide the subsequent therapy based on these data; carcinomata can occure in yound generation; and furthermore the clinicians should make full use of histopathological informations and they should not merely be influenced by its diagnosis.
