Enormous variability in skin colour and patterning is a characteristic of teleost fish, including Salmonidae fishes, which present themselves as a suitable model for studying mechanisms of pigment patterning. In order to screen for candidate genes potentially involved in the specific skin pigment pattern in marble trout (labyrinthine skin pattern) and brown trout (spotted skin pattern), we conducted comparative transcriptome analysis between differently pigmented dermis sections of the adult skin of the two species.

Birds have various plumage color patterns, and spot is a common phenotype. Herein, we conducted genome-wide association studies (GWAS) in a population of 225 ducks with different sized black spots to reveal the genetic basis of this phenomenon.

Evidence of increasing age includes wrinkles and sagging skin. Aging skin appears thinner, more pale, and clear (translucent). Thus, skin is at higher risk for injury. Large pigmented spots (called age spots, liver spots, or lentigos) may appear in sun-exposed areas. The blood vessels of the skin become more fragile. This leads to bruising, bleeding under the skin. Women’s skin gradually produces less oil beginning after menopause. This can make it harder to keep the skin moist, resulting in dryness and itchiness. The sweat glands produce less sweat.

In tuberous sclerosis, the earliest cutaneous sign is an ash leaf spot. These lesions are often present at birth and are usually multiple; however, detection may require Wood's lamp examination, especially in fair-skinned individuals. The pigment within them is reduced but not absent. The average size is 1–3 cm, and the common shapes are polygonal and lance-ovate.
