Friend, when the skin turns black it is called hyperpigmentation. This usually occurs secondary to an inflammatory process secondary to infections, allergies, etc. What happens is that inflammatory cells (macrophages) release melanin during the inflammatory response, melanin is what causes the black color. The black color will most likely not go away, it is not harmful just a consequence of inflammation. This pigment change can also occur secondary to hormonal disorder like hypothyroidism, cushing's etc.
Before going in for a biopsy I would recommend you discuss with your vet about doing some blood work to make sure this hyperpigmentation is not secondary to a hormonal disorder like hypothyroidism. If all blood work is normal then the next step would be to consider a biopsy.
