HISTOPATHOLOGICAL VARIANTS OF NEUROFIBROMA - A STUDY OF 114 LESIONS

Although neurofibroma is a relatively common tumor, some histopatholog ic variants are so rare that they are not well known. In a study of 13 0 neural cutaneous tumors seen between 1986 and 1991 in the department of dermatology at the University of Heinrich-Heine, we identified 114 neurofibromas of different types. We present herein the histopatholog ical features of these tumors. The differentiating features from other neural tumors-melanocytic or mesenchymal tumors that display ''neuroi d'' features-are also discussed.
