Concurrent beau lines, onychomadesis, and retronychia following scurvy
1Duke University School of Medicine, Durham, North Carolina, USA.
Abstract:
Beau lines, onychomadesis, and retronychia are nail conditions with their own characteristic clinical findings. It has been hypothesized that these 3 disorders may share a common pathophysiologic mechanism of slowing and/or halting nail plate production at the nail matrix. We report the case of a 41-year-old woman who presented with concurrent Beau lines, onychomadesis, and retronychia 6 months following a diagnosis of scurvy. Simultaneous presentation of these 3 nail conditions is not commonly reported, and our case supports a shared pathophysiologic basis.

Accessory Structures of the Skin: Nails
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

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...
