<bot>: Thanks for consulting in Healthcare. We should differentiate next diseases:1. Iron deficiency anemia caused lack of iron in the food.2. Lupus erythematous, which we exclude after blood test3. Lungs problems;bronchoectasis4. Polycythemia, a condition where the blood is too thick5. Fungal infection A blue spot on the neck is more often Mongolian blue spot, congenital, a benign, flat, congenital birthmark with wavy borders and irregular shape. Do you know it is also extremely prevalent among other East, Asian peoples? Mongolian blue spot usually disappear till the end of first year.  What should you do. If I were your doctor I would check your daughter blood test: hemoglobinum, RBC etc, iron, liver test, check lungs function, consult at dermatologist. Best regards Chat Doctor.
