Although a picture of it would help to give you more specific answers, this growth should be ideally examined by your veterinarian to have a definitive diagnosis. Your vet will examine it and possibly perform with an FNA (fine needle aspiration) or a biopsy. Differentials would include skin cyst, infections or benign or malignant type of tumors. From your description this mass could be a lipoma ( a benign type of tumor, coming from fat tissue).
