So, there are a number of things this could be. 1) This could be an allergic response to something in her environment or an insect, 2) This could be a fungal or bacterial infection that could be primary OR secondary to trauma or an allergy. Ideally I would do a prep on a slide and look under the microscope to see if there is a significant bacterial or yeast population. Regardless, however, I think she would benefit from some topical treatment depending on what is seen under the microscope. If it seems to be spreading, and the area is swollen, some injectable or oral medications may be indicated.
