Cylindrical cell papilloma. Report of a case with light and ultrastructural analysis.
The clinicopathologic features of an additional case of cylindrical cell papilloma are reported. This tumor is relatively rare, with approximately twenty cases recorded under that name in the literature. Surgical correction of papillomas in the nose and paranasal sinuses is discussed. Ultrastructural analyses suggest that cylindrical cell papilloma may possibly be an oncocytic lesion and thus different from the inverted and fungiform types.
