A cutaneous sinus tract due to periapical cyst being very rare may easily be misdiagnosed, leading to incorrect treatment. Identifying the etiology is difficult, but it is the key to effective therapy. The case presented here is a cutaneous sinus tract in the nasolabial region of odontogenic origin. After surgery and extraction of the tooth, the sinus tract healed remarkably (Belmehdi et al. in Contemp Clin Dent 9:314-318, 2018; Latifa et al. in Clin Case Rep 10:e05333, 2022).
