Abstract:
Cutaneous sinus tract on the head and neck area in a child may originate from dental disease. A high degree of clinical suspicion and complementary tests are often needed, as the diagnosis is usually not straight forward. Anatomical correlation is also useful in tracing the affected tooth or teeth. We present the case of a boy with a facial sinus tract that originated from periapical abscesses of maxillary molars.
