It has been reported that some patients have been misdiagnosed with Ewing's Sarcoma, when in fact the correct diagnosis in their specific case was Neuroblastoma.
Neuroblastoma is a type of cancer that forms of nerve cells while the embryo develops in pregnancy, so this cancer type is found in infants and children. This cancer can be found anywhere in the body where there are nerves. Symptoms include lumps in the neck, chest, abdomen that may appear blue or purple, bulging eyes or dark circles under the eye, fatigue, pale skin, trouble breathing, weakness and movement problems. Since this type of cancer is so rare it can be easily missed by doctors and the majority of symptoms are very similar to other common diseases of childhood.
