Acrocyanosis is common initially after delivery in the preterm and full term newborn. [13] Intervention is typically not required as it is seen as a normal finding. Acrocyanosis can also return in a newborn if a baby is cold, such as after a bath, and is considered normal as well. [14]
Cold agglutinin-mediated acrocyanosis differs from Raynaud phenomenon. In Raynaud phenomena, caused by vasospasm, a triphasic color change occurs, from white to blue to red, based on vasculature response. No evidence of such a response exists in cold agglutinin disease. Other symptoms
Secondary cold agglutinin syndrome occurs when autoantibodies bind to red blood cells, rendering them subject to attack by the complement system. [17] It is a result of an underlying condition potentially associated with either monoclonal cold-reacting autoantibodies or polyclonal cold-reacting autoantibodies [16] predominantly caused by infection or lymphoproliferative disorders. [16]
Symptoms of AIHA may be due to the underlying anemia; including shortness of breath or dyspnea, fatigue, headache, muscle weakness and pallor. [10] In cold agglutinin disease (cold antibody type), agglutination and impaired passage of red blood cells through capillaries in the extremities causes acrocyanosis and Raynaud phenomenon with a rare complication of gangrene [4]
The diagnosis is made by the clinical picture and the chest X-ray, which demonstrates decreased lung volumes (bell-shaped chest), absence of the thymus (after about six hours), a small (0.5–1 mm), discrete, uniform infiltrate (sometimes described as a "ground glass" appearance or "diffuse airspace and interstitial opacities") that involves ...
Of these, 5 (25%) had died at or before 30 months of age. Of the survivors, 1 (5%) was severely disabled and the remainder had either suffered mild disability or were making normal progress in school. [11] A 2006 Dutch study followed 155 cases and found that 27 individuals (17%) had died at an early age.
A Mongolian spot, also known as slate grey nevus or congenital dermal melanocytosis, is a benign, flat, congenital birthmark with wavy borders and an irregular shape. In 1883, it was described and named after Mongolians by Erwin Bälz, a German anthropologist based in Japan, who erroneously believed it to be most prevalent among his Mongolian patients.
