Question: What are the symptoms of Giant congenital nevus ?
Answer: What are the signs and symptoms of Giant congenital nevus? The Human Phenotype Ontology provides the following list of signs and symptoms for Giant congenital nevus. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Hypertrichosis 50% Hydrocephalus 7.5% Hypopigmented skin patches 7.5% Pruritus 7.5% Sarcoma 7.5% Seizures 7.5% Autosomal dominant inheritance - Broad forehead - Broad nasal tip - Congenital giant melanocytic nevus - Cutaneous melanoma - Deep philtrum - Full cheeks - Long philtrum - Narrow nasal ridge - Open mouth - Periorbital fullness - Prominence of the premaxilla - Prominent forehead - Round face - Short nose - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

Question: What are the treatments for Giant congenital nevus ?
Answer: How might giant congenital nevus be treated? Treatment for giant congenital nevus depends on the age of the affected individual as well as the size, location, and thickness of the nevus. Surgery may be done to remove the nevus, particularly when there is a concern that it may develop into a melanoma. When small nevi are removed, the surrounding skin can often be pulled together with stitches. Larger nevi may need to be removed in several stages and full-thickness skin grafts may be needed to help the skin heal following surgery. Laser treatments may be used for superficial skin imperfections, including reducing pigment and hair, but cannot completely remove the nevus. Affected individuals should self-monitor and continue to have regular skin examinations to check for benign or malignant tumors. Early awareness will allow their physicians to adjust treatment protocols accordingly. Children are most likely to show neurological signs before primary school and can respond well to a range of symptomatic therapies.
