Observation: A 19-week-old patient seen in an oral dermatology clinic had small labial commissures pits associated with auricular abnormalities. Similar clinical elements were found in the family medical history. A diagnosis of branchio-oto-renal syndrome (BOR) was quickly evoked. Commentary: BOR syndrome is a rare disease. This autosomal dominant pathology is characterized by facial lesions and renal abnormalities. Diagnosis is based on many clinical criteria. An optional genetic study can sometimes assist in diagnosis.
