Cutaneous changes in hypothyroidism

The association of thyroid disorders with skin manifestations is complex. Both hypothyroidism and hyperthyroidism are known to cause these changes. In order to study this association of skin changes in relation to hypothyroidism, a study was carried out in the Out Patients Department of Dermatology of Dayanand Medical College and Hospital, Ludhiana, over a period of 3 months from Jan - March 2005. Thirty two patients were enrolled in the study and parameters were noted regarding history, general symptoms, cutaneous signs and associated diseases. We found gain in weight (71.85%) and lethargy (65.62%) to be the most common complaints. On cutaneous examination dry, coarse texture of the skin (56%), telogen effluvium (40.62%) and pigmentary disorders (37.5%) were most common findings. Other associated disorders were vitiligo, melasma, pemphigus, alopecia areata, xanthelasma palpebrum, etc.
