Not : Not enough information for a diagnosis. Many possible causes. Recommend and examination by a dermatologist.

Any : Any non-healing skin lesion over this length of time should be looked at by a dermatologist to evaluate need for biopsy. This could be anything from a benign hyperkeratotic lesion, to a pre-malignant lesion such as actinic keratoses, to malignant basal or squamous cell carcinoma, among other things. The bottom line is it needs to be seen by an experienced clinician.
