I think your differential is good Nitin, the images also made me think of FRS but I could not see the elastotic material which is usually prominent. I think this is more like a reactive condition, there are open comedones, milia and there is an area of the stratum corneum with compact hiperkeratosis and an area that reminds me of a cornoid lamellae (secondary, not due to a poroketarosis). I thought and option could be that this lesion is related to steroid injections but CPC is essential as I think we cannot make a more specific diagnosis only with this images.

I have checked and apparently there are some rare cases of FRS without solar elastosis so the differential that you originally mentioned Nitin stands

Agree with above comment and favour FRS because there are vellus hair cysts and comedones, and sun exposition with elastosis has been debated...

Yes Favre Racouchot first thought too. Absence of elastotic material certainly unusual and the other diffetential that comes to mind is of nevus comedonicus.(some cases can present later in life). Clinical correlation essential.

Agree with Favre-Racouchot syndrome. I think elastotic material is present. I can see it in last figure, for example, if I enlarge it.

How about nevus comedonicus in the differential

Nevus comedonicus. Patient without significant sun exposure and solitary long standing lesion from youth. Clinically not FRS. No steroid history.
