title: [Balloon cell nevi of the conjunctiva (author's transl)].
abstract: The clinical and histological features of three cases of conjunctival balloon cell nevi are described. This peculiar form of nevus is very rare in the conjunctiva. The findings are compared with the descriptions in the literature of dermal balloon cell nevi. They demonstrate, that the conjunctival and dermal tumours are of idential histological structure. The proliferations of the conjunctival epithelium often found in conjunctival nevi do not modify the balloon cell nevi. These can not be diagnosed clinically. The problems of the pathogenesis of the balloon cell nevi are discussed.
