Abstract

Objectives: Oral carcinoma cuniculatum (OCC) is a rare variant of squamous cell carcinoma (SCC). It has similar clinicopathological characteristics to SCC and verrucous carcinoma (VC). We present a case series of OCC and analyse its unique features, diagnosis, and management. Patients and Methods: We retrospectively reviewed the medical records of oral cancer patients treated by Oral and Maxillofacial Surgery department from 2009 to 2020 with OCC biopsy findings. The clinicopathological characteristics and management of the OCC cases were analysed. Results: Four patients were identified with histologic findings of OCC, including three on the alveolar ridge mucosa and one on the tongue. Imaging revealed that two of the lesions located in the maxilla had osseous lysis. All four patients were all treated with radical excision, and the histopathology showed findings of SCC cuniculatum. It was decided that no further treatment was necessary. None of the patients has experienced recurrence during follow-up. Conclusion: OCC is a distinct entity that is more locally aggressive than VC but is associated with good prognosis. Radical surgical removal is considered appropriate for OCC. Emphasis should be given on an early diagnosis, as it remains challenging.
