Epidermis, including hair follicles & glands, is derived from ectoderm. Many severe burns and scalds affect babies and young children. These very painful burns look pink, moist and soft. Pathophysiology. The four stages of wound healing are: Hemostasis Phase. The dermis forms two layers and is composed of connective tissue—the papillary layer and the reticular layer. These basal cells form a single layer and adhere to one another as well as to more superficial squamous cells through desmosomal junctions (Murphy, 1997). Benign and malignant characteristics of breast lesions at ultrasound allow the classification as either malignant, intermediate or benign based on work published by Stavros et al.
