Changes in skin morphology six weeks after 5 × 15 Gy radiotherapy. H&E stained section of the skin epidermis and dermis of non-irradiated control rats (a) and 5 × 15 Gy irradiated rats (b). The histologic examination demonstrates alopecia and a dense network of collagen fibers with few cells, increased fibrosis, of the dermis after irradiation. Furthermore, the stratum corneum, the outermost layer of the epidermis, is thicker after irradiation. Scale bar indicates 200 μm
