Woolly hair nevus - Case report

Area of Science:

• Dermatology
• Genetics
• Pediatrics

Background:

• Woolly hair nevus is a rare congenital condition characterized by abnormal hair shaft structure.
• Mongolian spots are benign, congenital hyperpigmentations typically found in the lumbosacral area.
• The co-occurrence of these two distinct conditions is infrequently documented.

Purpose of the Study:

• To report a unique case of woolly hair nevus associated with a Mongolian spot.
• To contribute to the limited literature on the simultaneous presentation of these dermatological findings.
• To highlight the importance of recognizing rare congenital anomalies.

Main Methods:

• Clinical case presentation.
• Dermatological examination.
• Review of relevant medical literature.

Main Results:

• A patient presented with clinical features consistent with woolly hair nevus.
• The same patient also exhibited a Mongolian spot.
• No other significant congenital anomalies were identified.

Conclusions:

• The co-occurrence of woolly hair nevus and Mongolian spot, while rare, can be observed.
• This case underscores the variability in congenital dermatological presentations.
• Further research may elucidate potential shared etiologies or associations.
