Insights
Bilateral lip pits, a rare congenital condition, typically occur with other syndromes. This case highlights an extremely rare nonsyndromic presentation, crucial for accurate genetic counseling.
Area of Science:
- Medical Genetics
- Developmental Biology
- Craniofacial Anomalies
Background:
- Lip pits are congenital indentations of the lip, often inherited as an autosomal dominant trait.
- They are frequently associated with cleft lip/palate and various genetic syndromes like Van der Woude's syndrome.
- Nonsyndromic lip pits are exceptionally rare, with few documented cases.
Observation:
- This report details a unique case of bilateral lip pits presenting without any associated systemic or craniofacial anomalies.
- The patient exhibited symmetrical indentations on both sides of the upper lip, a rare occurrence in isolation.
Findings:
- The presented case is a rare instance of nonsyndromic bilateral lip pits.
- This finding underscores the importance of considering isolated lip pits in differential diagnoses.
Implications:
- Accurate identification of lip pits, whether syndromic or nonsyndromic, is vital for effective genetic counseling.
- Understanding the spectrum of lip pit presentation aids in diagnosing and managing associated conditions.
- This case expands the known clinical variability of lip pit anomalies.
Abstract:
Lip pits are a rare congenital anomaly that presents on the upper or lower lip or the commissure of the lips. Lip pits are an autosomal dominant trait occurring almost always in association with cleft lip or palate. They most commonly occur in association with developmental disturbances such as Van der Woude's syndrome, popliteal pterygium syndrome, oro-facial-digital syndrome, Marres-Cremers syndrome, and Hirschsprung disease. Its occurrence in nonsyndromic individuals is extremely rare with only a handful of cases reported. The identification of lip pits with other associated anomalies is crucial for genetic counseling; we report a case of nonsyndromic presentation of bilateral lip pits.
