Infected type 1 congenital upper lip sinus in 8 years child: A rare case report

Area of Science:

• Medical Genetics
• Developmental Biology
• Oromaxillofacial Surgery

Background:

• Congenital lip sinus, also known as a lip pit, is a rare developmental anomaly.
• Lower lip sinuses are more common than upper lip sinuses, with limited documented cases of the latter.
• These anomalies can occur independently or be associated with other congenital conditions like cleft lip/palate.

Observation:

• An 8-year-old girl presented with symptoms of infection in a midline upper lip pit.
• The pit was located below the columella at the philtrum, exhibiting pain, swelling, and purulent discharge.
• This clinical presentation is consistent with a Type 1 congenital upper lip sinus.

Findings:

• The patient was diagnosed with a Type 1 congenital upper lip sinus.
• This diagnosis is based on the location and clinical presentation of the lip anomaly.
• The rarity of upper lip sinuses, especially Type 1, makes this case noteworthy.

Implications:

• This case underscores the importance of recognizing rare congenital lip anomalies.
• Accurate diagnosis is crucial for appropriate management and to rule out associated conditions.
• Further documentation of upper lip sinus cases can contribute to understanding their etiology and prevalence.
