What is this bald spot?

In evaluating this spot, a knowledgable surgeon will know or want to find out:

1- This location is not typical for Triangular alopecia as it is  too far back from the temple peak.

2- What does the trichoscopy show as there are hairs within the bald spot that might shed light on the diagnosis (will rule in or out alopecia areata)

3- Most likely that this is not genetic patterned balding as it is not located in the patterns for such balding

4- This is a clean scar sitting inside normal hair, likely a form of alopecia that has a clear “cut” border

It turns out that this lesion was biopsied, and the diagnosis was definitive for Citrical Alpecia (scarring alopecia). This man had this for many years, and it was stable, suggesting that the disease had already done its damage and could be, therefore, transplanted as was done with good immediate results. The problem with such diseases is that:

1- It could return at the site and kill all of the transplanted hair

2- it could appear at another site and do the same damage

3- if the disease was active during the transplant, it would either immediately kill the new hairs as they started to grow or slowly kill off the new hairs over time.
