A thread has been done on that before.
2. Chloasma (Melasma in pregnancy). -Sun avoidance and protection with sunscreen and counseling on the fact that it is managed rather than cured

3. Inflammatory Linear Verrucous Epidermal naevus (ILVEN). Some people got it precisely!
4. Acute Paronychia. Some were mentioning Felon. Paronychia is at the proximal nail fold and a felon is at the distal finger pulp. Acute because of the short duration and pain

5. Ichthyosis vulgaris. The history I gave. Condition usually Aut. Dominant. May be associated with atopic dermatitis.
6. Herpes Zoster. Nobody should miss this. Brought it here because I still got a consult for it last year which was surprising.
