Area of Science:

• Genetics and human pathology
• Dermatology and oncology

Background:

• Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant genetic disorder.
• It is characterized by a spectrum of developmental abnormalities, including skeletal anomalies, multiple basal cell carcinomas, and jaw keratocysts.

Observation:

• The syndrome exhibits variable phenotypic expression and incomplete penetrance.
• NBCCS can arise de novo (spontaneously) in individuals without a family history.
• The prevalence is estimated at 1:60,000, with 50-65% of cases having affected relatives.

Findings:

• A case study of a recently diagnosed patient with NBCCS is presented.
• The diverse clinical manifestations of the syndrome are discussed in detail.
• This highlights the importance of recognizing the varied presentation of NBCCS.

Implications:

• Early diagnosis and management of NBCCS are crucial for preventing complications.
• Understanding the genetic basis and variable expressivity aids in patient counseling and risk assessment.
• Further research can improve diagnostic strategies and therapeutic interventions for NBCCS patients.
