The sections show skin with epidermal hyperplasia, parakeratosis and a thickened granular cell layer. The subepithelial tissue has a scattered perivascular lymphocyte predominant inflammatory infiltrate that extends to the cartilage. The cartilage shows focal ischemic changes and perichondral inflammation. Focal chondral necrosis and microabscess formation is identified. Maturing granulation tissue is seen adjacent to the cartilage. | |||
