1Clear: Lesion contains primarily clear connective tissue.
2Woody: Lesion contains organized connective tissue and fat.
3Nodular: Lesion contains nodules, a central foci, and granulomatous inflammation.
4Metallic: Lesion contains mineralized remnants of muscle cells, typically bloody color.
5Cystic: Lesion contains fluid.
