A glow-up went wrong for this US woman who became the first recorded patient with dermatomyositis from getting her nails done.

The uncommon, idiopathic condition is characterised by acute inflammatory myopathy and cutaneous manifestations such as Gottron papules, Gottron sign and heliotrope rash.

In this case, the UV lamp used to cure the nail polish caused the rare inflammatory myopathy, Pennsylvanian doctors wrote in JAAD Case Reports.

The patient, 34, developed erythematous papules on the dorsal aspects of her hands a day after her manicure, before embarking on a planned week-long vacation in the sun.
