L51.9
DESCRIPTION
A self-limiting and commonly recurrent inflammatory eruption of the skin. Sometimes involves mucous membrane (but not more than one surface) and without systemic symptoms. Usually lasts for 10-14 days before complete recovery occurs.
Symmetrically distributed crops of target lesions (dark centre, an inner, pale ring surrounded by an outer red ring) occur on the extremities and in particular on the backs of the hands and forearms, palms and soles. This condition is usually due to an infection, commonly herpes simplex or mycoplasma.
REFERRAL
