A case of lichen myxedematosus with clearly exacerbated skin eruptions after UVB irradiation.
We report a 48-year-old male with typical lichen myxedematosus, liver dysfunction, and diabetes mellitus. His skin eruptions were clearly exacerbated after accidental over-irradiation by UVB. These findings were clinically and histologically confirmed. The pathogenesis is still unknown, but we consider it to be due to Koebner phenomenon.
