Abstract

We thank Kaserer and Hantich for their comments that raise several interesting points. Ackerman1 does indeed use the term trichoblastoma inclusively to describe all benign neoplasms of follicular germinative cells. Headington,2 however, prefers to classify the trichogenic tumors into two primary groups, epithelial and mesenchymal, analogous to the odontogenic tumors. In this scheme, a trichoblastoma is an epithelial trichogenic tumor without inductive change whereas trichoblastic fibroma is an epithelial trichogenic tumor with stromal induction, both of which are more specific and precise definitions. It is based on this latter definition that we chose to classify our series of tumors.

We agree that the nomenclature for adnexal neoplasms in general and trichogenic tumors in particular may be cumbersome and confusing. Our wish is not to make matters worse, but rather to continue to describe, define, and refine our observations in the hopes to be better morphologists. The information obtained,
