Dentinogenic ghost cell tumour (DGCT) is a very rare aggressive benign odontogenic tumour with high recurrence rate and a potential to transform into malignancy. It can render facial disfigurement. The tumour is most frequently encountered in males than females with a ratio of 2:1. The peak incidence is in patients aged 40 - 60 years and the posterior mandible is slightly more affected than the maxilla. Segmental resection is a recommended surgical treatment and long-term postsurgical follow up is essential. This paper discusses a case of a 20-year-old African female patient who was diagnosed with a DGCT.
