Full description

Melasma is an acquired and chronic disorder of hyperpigmentation characterized by symmetrical hypermelanoses of the face. The exact pathogenesis of melasma is still unknown. Several hormones are thought to play a role, including thyroid hormone. Although melasma is not life-threatening, it affects greatly on the quality of life of patients. Study's objectives are to determine proportion of melasma cases in hyperthyroid patients and to compare severity of melasma before and after medications of three months hyperthyroid therapy using mMASI score. An experimental (before and after) study was conducted in Jakarta in August 2019-February 2020. Twenty three newly-diagnosed hyperthyroid patients or had taken hyperthyroid medications of maximum 3 months with melasma were recruited. The severity of melasma were scored with mMASI and dermoscopy of the lesions were collected. The same procedures were done after 3 months of hyperthyroid therapy. The data collected was statistically analyzed using Stata version 15.0
