Aplasia cutis congenita


Title




Other Names:
Aplasia cutis congenita nonsyndromic; Congenital defect of skull and scalp; Scalp defect congenital
Categories:
Congenital and Genetic Diseases; Skin Diseases

Summary Summary


Listen
Aplasia cutis congenita is a condition in which there is congenital (present from birth) absence of skin, with or without the absence of underlying structures such as bone.[1] It most commonly affects the scalp, but any location of the body can be affected.[2] While most people with aplasia cutis congenita have no other abnormalities, some people have congenital malformations involving the cardiovascular (heart), gastrointestinal, genitourinary, and central nervous systems.[1] The cause of this condition is unclear and appears to be multifactorial (many different factors appear to play a role); contributing factors may include teratogens, genes, trauma, and compromised blood flow to the skin.[1]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause


Listen
There is no one cause for all cases of aplasia cutis congenita.[2][3] The condition is thought to be multifactorial, which means that several factors likely interact to cause the condition.[1][3] Factors that may contribute include genetic factors; teratogens (exposures during pregnancy that can harm a developing fetus) such as methimazole, carbimazole, misoprostol, and valproic acid; compromised vasculature to the skin; and trauma.[1][3][1] Some cases may represent an incomplete or unusual form of a neural tube defect.[4] Familial cases of aplasia cutis congenita have been reported.[1][4] Cases that appear to be genetic may be inherited in an autosomal dominant or autosomal recessive manner.[4]

Treatment Treatment


Listen
Treatment of aplasia cutis congenita varies depending on the condition of the infant. Conservative treatment is preferred.[5] Small areas usually heal on their own over time. Gentle cleansing and application of bland ointments or silver sulfadiazine can help prevent infection. If infection occurs, antibiotics can be used.[3][6] Recently, a variety of specialized dressing materials have been developed and used.[3] Larger lesions may require surgery.[3][6] Ultimately, the decision to use medical, surgical, or both forms of therapy depends primarily on the size, depth, and location of the skin defect.[3]

    Prognosis Prognosis


    Listen
    The long-term outlook (prognosis) for people with aplasia cutis congenita is usually excellent. If the condition is associated with other abnormalities or malformations, the prognosis then depends on the nature and severity of the other condition(s).[3]

    Major complications of aplasia cutis congenita are rare, but can include hemorrhage, secondary local infection, meningitis, or sagittal sinus thrombosis. Larger affected areas associated with underlying bony defects can cause death due to central nervous system infection, or hemorrhage from the sagittal sinus. Complications can also result from associated abnormalities or malformations, when present.[3]

    If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

    If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

    You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

    Healthcare Resources

    • To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from MedlinePlus Genetics.

    Related diseases are conditions that have similar signs and symptoms. A health care provider may consider these conditions in the table below when making a diagnosis. Please note that the table may not include all the possible conditions related to this disease.

    Conditions with similar signs and symptoms from Orphanet
    Differential diagnoses include traumatic lesions, localized scalp infections, dermoid cyst (facial, cervical, nasal or involving the central nervous system), isolated encephalocele, meningocele and nodular neuronal heterotopia. As the child grows and scarring occurs, sebaceous nevus, nevus psiloliparus, localized scleroderma and other types of cicatricial alopecia should be considered. Hypertrophic scars can be mistaken for scalp tumors. ACC can occur in association with inherited epidermolysis bullosa and with epidermal and organoid nevi (didymosis aplasticosebacea). It may also form part of numerous syndromes including: chromosomal abnormalities (mainly trisomy 13), Adams-Oliver syndromes, Johanson-Blizzard, SCALP syndrome, focal facial dermal dysplasia, oculocerebrocutaneous syndrome, scalp-ear-nipple syndrome, Toriello-Lacassie-Droste syndrome, aplasia cutis congenita-intestinal lymphangiectasia syndrome, aplasia cutis-myopia syndrome, cutis verticis gyrata-thyroid aplasia-intellectual disability syndrome, and others.
