Neonatal diagnosis of circumferential skin creases.

BACKGROUND: Circumferential skin creases is a rare and heterogeneous disorder characterized by multiple and redundant skin folds, which can present as an isolated feature or in association with other phenotypic anomalies. Here, we report the case of a newborn who immediately captured our attention because of his phenotype. CASE: A male Caucasian infant was born at 39 weeks and 4 days of gestational age with an instrumental delivery, after a pregnancy characterized by threat of preterm birth at 32 weeks. Fetal ultrasounds were reported to be normal. The patient was the first child of non-consanguineous parents. Anthropometry at birth: weight 3.590 kg (0.57 SDS); length 53 cm (1.73 SDS); cranial circumference 35.5 cm (0.83 SDS). Clinical examination soon after birth revealed multiple, asymmetric and deep skin folds involving forearms, legs and lower eyelids (right > left). These folds seemed not to cause any physical discomfort. In addition, hypertrichosis, micrognathia, low-set ears and a thin, down-turned border of upper lip were observed. Cardio-respiratory, abdominal and neurological examination was unremarkable. There was no family history of similar appearance or other physical abnormalities. Given the clinical picture, an array-CGH was performed, which was normal. A genetic counseling was requested and Circumferential Skin Creases disorder was diagnosed based on the typical cutaneous involvement and, given the absence of other clinical signs, it was supposed a benign evolution, with skin folds tending to disappear over time. In addition, the baby's DNA was requested for a targeted genetic analysis, which resulted negative. CONCLUSIONS: This clinical case underlines the need of performing a detailed neonatal physical examination in order to realize a timely diagnostic approach. Our patient presented with multiple skin folds, facial dysmorphism but normal systemic and neurological examination. Anyways, since Circumferential Skin Creases may be associated with later neurological symptoms, a regular reevaluation is recommended.

The clinical approach plays a pivotal role in neonates with evidence of a skull mass, together with the need of monitoring unclear cases. Indeed, apparently transient alterations of the skull may be neural tube defects, which need prompt treatment.
