Dyskeratotic cells in the epidermis with a mild lymphocytic infiltrate. (D) Patient no. 1 after therapy (H&E stain; magnification × 200). Improvement of the epidermal features. (E) Patient no. 6 before therapy (Sirius red stain; magnification × 200). Compact, severely thickened collagen in the superficial dermis. (F) Patient no. 6 after therapy (Sirius red stain; magnification × 200). The collagen is less compact. (G) Patient no. 6 before therapy (CD68 stain; magnification × 200). A few macrophages are present in the superficial dermis. The arrows in panel G indicate CD68-positive macrophages. (H) Patient no. 6 after therapy (CD68 stain; magnification × 200). The macrophages have disappeared. The microscope used was a Nikon Eclipse E800M with a Nikon Plan apo 20 × objective. The camera used was a digital Nikon FDX-35.
