Diagnostic Pitfalls: An Odontogenic Cutaneous Sinus Tract Masquerading As Chromoblastomycosis

Odontogenic cutaneous sinus tracts occurring in the facial and neck areas are uncommon and pose a diagnostic difficulty for clinicians due to their potential association with various conditions. This case report details the successful management of a non-healing odontogenic sinus tract in the chin area, which had previously been histopathologically diagnosed and treated as chromoblastomycosis. The patient was presented with a persistent sinus tract with purulent discharge that had not responded to previous treatments. A thorough clinical examination and radiographic imaging revealed an underlying dental infection as the cause of the sinus tract. The excision of the sinus tract was performed, along with extraction of teeth to address the underlying infection. The patient experienced complete resolution of the sinus tract and remained asymptomatic during follow-up visits. This case highlights the importance of a comprehensive approach to diagnose and treat odontogenic sinus tracts, successful outcomes achievable through a combination of surgical intervention and dental management.
