Abstract:
We report on the prenatal sonographic appearance of epidermolysis bullosa (EB). The third viable pregnancy of a consanguineous couple was found at 23 weeks to have dysplastic external ears and nose. The neonate was born at 33 weeks and was found to have junctional EB with pyloric atresia. On reviewing the 23-week ultrasound images, skin denudation was evident. This is a report of visualization of skin denudation in EB. When EB is suspected prenatally, special attention should be given to the visualization of skin surfaces.

Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Cells of the Epidermis
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
