Chapter 103 - Neonatal dermatology part II Flashcards
Single minor congenital anomalies occur in approximately ___% of all newborns
15
___ or more minor congenital anomalies is unusual and warrants a complete thorough physical examination to rule out other congenital abnormalities
3
For midline nasal and facial lesions, ___ is indicated to rule out intracranial connection before skin biopsy is performed
radiologic evaluation
High risk factors of occult dysraphism (5)
2 or more lesions of any kind One lesion + spinal cord dysfunction Lipoma Tail Dermal sinus
Intermediate risk factors for occult spinal dysraphism (4)
Atypical sacral dimple (>/=5mm diameter in location, >/=2.5 cm away from anus)
Aplasia cutis congenita
Overting hamartoma
Deviated gluteal cleft
Low risk for occult spinal dysraphism (5)
Port wine stain Hypertrichosis Pigmented nevus Simple sacral dimple (<5mm diamter, 2.5 cm or closer to the anus) Mongolian spot
For high risk for occult spinal dysraphism, ___ is recommended
MRI
For intermediate risk for occult spinal dysraphism, ___ is recommended
Ultrasonography if younger than 4 mos old then MRI if abnormal
MRI if older than 4mos
Congenital anonalies that arise along planes of embryonic fusion of the face and scalp
Dermoid cysts
Treatment for dermoid cyst
Surgical excision
Dermoid cysts are not always apparent at birth.
True or False
True
Firm, skin-colored to erythematous nodules on the nose composed of heterotopic neural tissue
Nasal glioma
Most common presentation of spina bifida
Myelomeningocele
Neural tissue of spinal cord is present
Midline, formed when the meninges and CSF herniate through a defect in the calvarium or vertebrae
Meningocele
Herniation of neural tissue along with meninges and CSF through a calvarial defect
Encephalocele
Vestigial appendages that may be composed of adipose tissue, blood vessels, muscle fibers, and nerves
Human tails
Examples of pseudotails
Sacrococcygeal teratoma
Myelomeningocele
Both true human tails and paeudotails are associated with spinal dysraphism and warrants MRI examination
True or False
False, only true human tails
Most common branchial cleft anonaly
Branchial cysts
2nd branchial arch - sternocleidomastoid on lateral aspect of the neck
Definitive treatment for branchial cleft anomalies and thyroglossal duct cysts
Surgical excision
Congenital neck anonalies that present as midline mass arising anywhere fron suprasternal notch to posterior tongue
Thyroglossal duct cysts
Present with persistent drainage from umbilicus or with an umbilical mass
Urachal and omphalomesenteric remnants
Failure of regression of urachus or fistula between bladder and umbilicus
Urachal cyst
Umbilical polyp or fistula between ileum and umbilicus
Omphalomesenteric duct
Common abnormalities of umbilicus that presents with persistent friable granulation tissue involving umbilicus after separation of umbilical cord
Umbilical granuloma
Treatment for umbilical granuloma
AgNO3 chemical cautery
Distort central facial features
Nasal glioma
Associated with dermal pit or sinus with significant risk of intracranial extension
Nasal dermoid cysts
Firm subQ mass at birth
Nasal glioma
Nasal glioma is not associated with intracranial connection.
True or False
True
Ring of darker and/or coarser terminal hairs on the scalp typically surrounding ACC, dermoid cyst, encephalocele, meningocele, or heterotopic brain tissue
Hair collar sign
Localized areas of absence of the skin and sometimes the underlying subQ tissues and bones
Aplasia cutis congenita
