The typical clinical features are well circumscribed bald patches. Vitiligo is an acquired skin disease of progressive melanocyte loss which is clinically characterized by well-defined milky-white macules. alopecia areata and vitiligo are observed with other autoimmune diseases .among these diseases, the chance of coexistence with autoimmune thyroid diseases is high.OBJECTIVE: To determine whether vitiligo or alopecia areata has statistically significant association with subclinical thyroid dysfunction.PATIENTS AND METHODS: This case control study was carried out on 69 vitiligo, 69 alopecia areata patients and 75 sex and age matched control. Serum samples from both patients and control were collected and assayed for triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH) then we compared the results between cases and control.RESULTS: Thyroid functional abnormalities were found in 18.8%, 13% of vitiligo and alopecia areata patients respectively, subclinical hypothyroidism constitutes 78%, 69% of them respectively .however when were compared with control group, there are no statistically significant differences in thyroid dysfunction between vitiligo or alopecia areata and control.CONCLUSION:There is no statistically significant difference in thyroid dysfunction between vitiligo or alopecia areata and control. Thyroid function test is unnecessary for alopecia areata or vitiligo patients unless the patient had signs and symptoms of thyroid disease, old age or severe clinical subtype of disease.
