How to treat this skin discoloration? Why is my patient experiencing this after getting exposed to the sun all the time, even after applying Sunscreen lotion? Thank you.
Is your patient getting hyperpigmentation or hypopigmentation?
I'm sorry it's unable to figure out from the attached image
Is it only on sun-exposed areas? Are there any other symptoms?
Does it just begins and remains as hypopigmentation?
We could think porphyria cutanea tarda but patient does not have any other symptoms
The rash does look like tinea but again it's only on sun-exposed areas
PLE and Solar Urticaria would also not begin just with hypopigmentation but can heal with post-inflammatory hypopigmentation
Could something in the history be missing from the patient?
