Please take a moment to look at the mottled skin pictures.

Understanding What is Mottled Skin

Mottled skin is technically called Livedo reticularis. The blood vessels start to spasm and the circulation process becomes abnormal. The skin takes on a purple marbled appearance.

You can usually decipher a netlike pattern and there are typically discernible borders. If you are wondering what is mottled skin? Then it is a symptom of a condition or underlying cause.

The Definition of Mottled Skin

It is a symptom or side effect of something. Frigid temperatures can cause it, but once you warm up the skin returns to its normal look. If you have mottled skin then you should seek medical help to determine the cause.

Pancreatitis: This inflammatory disorder causes in many body parts such as on stomach and on thighs.

Low Platelet Count: The mottling can occur on arms and on palms of hands but is nothing to worry about.

Age: The elderly have cardiac conditions, poor circulation, and other vascular problems that cause blue extremities.

Poor Circulation: Circulation disorders can occur in young and old alike. It often goes hand in hand cardiovascular diseases.

Rheumatoid Arthritis (RA): RA is an inflammatory disease that also attacks the blood vessels. With RA, the mottled pattern is dark and highly noticeable.

Cutis Marmorata in Newborn

Cutis Marmorata refers to mottled skin on a newborn. Lacy blue and red patterns form in baby when exposed to cold. Rewarming of the skin eases the physiologic response to cold. It happens because of an immature neurological and vascular system. The vessels alternate between constriction and dilation. You will notice it the most on the palms of hands and feet. If the disorder persists past infancy, it can show Down’s syndrome (trisomy 21), Cornelia de Lange syndromes, and Edwards (trisomy 18). Infants developing sepsis also display the telltale rash.

Cutaneous Marmorata Telangiectasia Congenita (CMTC) in Infants

Cutis marmorata telangiectatica congenita (CMTC) occurs at birth and is a congenital defect of the blood vessels that causes it to dilute them. The baby looks like it was wrapped in a blue fishnet because of the markings on the skin.

The look like bluish patterns is the crucial factor that lets the obstetrician know there is something wrong at birth.

  • Selenium sulfide available at drugstores as a shampoo
  • Itraconazole (brand name Onmel or Sporanox)
  • Ketoconazole (brand name Ketoconazole or Nizoral)
  • Fluconazole (brand name Diflucan)
