What it looks like: Actinic keratoses are pre-cancerous changes to the skin caused by sun damage, explains Dr. Zeichner. “The rash feels like sandpaper when you run your fingers over it.”
The pathophysiology is not yet well understood. Leukocytoclastic vasculitis is proposed to be the underlying cause resulting in reactive lymphedema. [2] Prolonged standing with full knee extension and minimal movement for a prolonged period of time is postulated to induce a temporary failure in pumping the venous and lymphatic systems in the calf region leading to acute gravity-dependent ...
Adult human bodies photographed whose naturally-occurring pubic, body, facial, but not head hair have been deliberately removed to show anatomy. Retouched with anterior and posterior views. There are functionally infinite variations in human phenotypes, though society reduces the variability to distinct categories.
Melanin is the protein that creates skin, eye and hair color. More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3.
Yellow nail syndrome, also known as "primary lymphedema associated with yellow nails and pleural effusion", [1]: 849 is a very rare medical syndrome that includes pleural effusions, lymphedema (due to under development of the lymphatic vessels) and yellow dystrophic nails. [2]
