Papillomas of the nose and paranasal sinuses: a clincio-pathologic study

Papillomas of nose and paranasal sinuses are uncommon tumours. Based on the detailed clinical and
histopathological examination of seven cases of papillomas, the authors would accept and recommend
t~e. su~ested unifying name of transitional cell papilloma for these lesions which may further be sub·
dIvIded onto Type I and Type II. The rationale behind this classification is discussed at length. There is
a greater tendency for Type II papillomas to recur and undergo malignant change. It is suggested that
Type I papillomas be managed by relatively simple surgical procedures whereas Type II cases be dealt with more radically.
