Abstract:
Biopsy for reticulate eruptions such as livedo reticularis and livedo racemosa representing an underlying vasculitis or vessel occlusion presents a challenge for most clinicians. Sampling errors frequently occur due to the difficulty in selecting the most appropriate and histologically representative site for biopsy. Here we describe a new technique where ultrasound is used to guide the biopsy with pinpoint accuracy to the affected vessel.

Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
