The dermatologist is right in that hypothyrodism does not perse cause depigmentation, but then the association of hypothyroidism,vitiligo, and pernicious anemia as a part of autoimmune disorder is emphasized, more as an association than a direct cause. Indeed idopathic guttate hypomelanosis is a possiblity here.
Hello,
Your aches and joint pains can be due to thyroid issues but for these white spots, the possibilities of pityriasis versicolor and idiopathic guttate hypomelanosis need to be ruled out. Thyroid diseases will cause dry, itchy skin but unlikely to cause hypopigmented spots. Pityriasis versicolor is caused by an overgrowth of a yeast fungus and are found mainly on sun exposed areas. To confirm the diagnosis you need to get it examined from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Oh yes, I did go through your other symptoms like depression which fairly well clinch the diagnosis.
they did just discover nodules on my thyroid, i didnt realize thyroid stuff could mess up skin - thank you!
Whith the sudden appearence of these hypopigmented macules, and your history of fatigue, you should get your Thyroid profile ,and CBC to rule out deficiency especially B-12.
