title: Skin findings in thyroid diseases.
abstract: BACKGROUND
  In cases of thyroid diseases, many of the symptoms arise on the skin. In this study, we aimed to detect and compare the skin findings and accompanying dermatoses of patients with thyroid diseases.
  
  
  METHODS
  220 patients with thyroid diseases, who did not have any medical cure, and 90 healthy individuals as a control group attended our study. All of the cases were examined, and the skin findings and/or dermatoses were recorded. The skin findings in the patients and the control group were compared statistically.
  
  
  RESULTS
  Among 220 cases, in 125 (56.8%) skin findings were detected. The most frequently observed skin findings were chronic urticaria (6.8%), vitiligo (6.8%), diffuse alopecia (6%), acne vulgaris (5%) and acne rosacea (3.6%). No significant difference was detected statistically between the patients and control group in terms of skin findings. When compared for the presence of each dermatosis, chronic urticaria, vitiligo and pruritus were found to be significantly higher in the patient group with thyroid diseases than in the control group. In terms of the presence of skin findings, no statistical difference was detected between autoimmune hyperthyroidism and non-autoimmune hyperthyroidism, between autoimmune hypothyroidism and non-autoimmune hypothyroidism, or between autoimmune euthyroidism and non-autoimmune euthyroidism. Chronic urticaria, vitiligo, and diffuse alopecia were found to be significantly higher in patients with autoimmune thyroid diseases than in the control group. Vitiligo and diffuse alopecia were found to be higher in autoimmune hyperthyroidism patients than in the control group. Vitiligo was found to be significantly higher in autoimmune hypothyroidism patients than in the control group.
  
  
  CONCLUSIONS
  To our knowledge, no report investigating the skin findings among thyroid diseases exists in literature. We believe this study would provide data for further studies.
