Hair follicle tumors: Be Hygienic and Immunogenic

Abstract

Viral M. Bhanvadia, MD *

Hair anatomy based classification of follicular tumors facilitates the diagnosis because the nomenclature of follicular tumors is descriptive and sometimes inconsistent. It is a classification that categorizes the entities based on the anatomic part of the follicle whose morphology they recapitulate. There are essentially four parts of the follicle from deep to superficial: the hair bulb, the supra bulbar zone (the stem), the isthmus and the infundibulum. The supra bulbar zone extends between the bulb and the insertion of erector pili muscle.
