Based on previous diagnostics I would proceed with a biopsy ( a larger sample) as well as a culture and sensitivity. If there is growth on the sample, I would proceed with a longer duration of antibiotics as indicated. It may be worthwhile in the interim to start a low dose of steroids to reduce any inflammatory/allergic response, but I would only start after collecting a good biopsy and culture. This could be an infection, but it is also possible that it is a type of neoplasia like lymphoma or mast cell and a larger sample is likely needed to determine.
