C4  HISTOPATHOLOGY OF ALOPECIA IN HORIZONTAL SECTIONS

Whiting D.A. Baylor Hair Research and Treatment Center, Dallas, Texas, USA.

This workshop will allow the participant to examine horizontal and vertical sections of scalp biopsies under the microscope.  The common causes of non-scarring alopecia such as androgenetic alopecia, diffuse alopecia, alopecia areata or traumatic alopecia, and of scarring alopecia such as lichen planopilaris, lupus erythematosus or folliculitis decalvans, may be included.

The methods of cutting horizontal sections and counting follicular structures will be discussed. These follicular counts and their diagnostic value in alopecia will be demonstrated.
