Nodular chondrodermatitis pathology

Histology nodular chondrodermatitis

Nodular chondrodermatitis helicis scan power view shows a wedge shape dermal alteration that extends to the superficial cartilage (Figure 1). the epidermis can show a focal Zone of orthokeratosis and scale Cortex moderate overlying epidermal hyperplasia (Figure 2). There will often be superficial epidermis ulceration. There is a zone of eosinophilic fibrinoid material that covers the affected area of cartilage, with blurring of the superficial cartilage and altered staining (Figure 3). There may be adjacent perichondrial thickening.

Differential diagnosis nodular chondrodermatitis

Pseudocyst of the atrium: although there may also be hyalinized degeneration above the affected collagen, a noepithelial lined cystic A space is formed within the collagen in the pseudocyst of the atrium.
