Solitary localised- This suggests a localised contact dermatitis if red and scaly with a broken surface or a fixed drug reaction if red and non scaly with slight hyperpigmentation. If recurrent vesicles preceded by localised pain then herpes simplex is the likeliest diagnosis.

You can try a manequin in the Diseases by Site link opposite to look at skin diseases by site or better still go to Global Skin Atlas Diagnosis and use the Specific Search Site function for a comprehensive list of diseases occuring at a specific site..
