BACKGROUND: Oral carcinoma cuniculatum (OCC) is a rare, locally aggressive tumor, which tends to invade underlying bone. We present two cases of OCC, one demonstrating invasion of the mandible and the other limited to the tongue.
METHODS: An 87-year-old male presented with a right-sided buccogingival lesion. Biopsy results led to a diagnosis of verrucous hyperplasia, which was later revised to OCC. Additionally, a 94-year-old female presented with a left lateral tongue lesion. A biopsy showed in-situ and invasive keratinizing squamous cell carcinoma that was later defined as a soft tissue OCC.
RESULTS: Following surgical resection, the diagnosis of OCC was established in both patients. We provide a comprehensive literature review of OCC in the context of both case presentations.
CONCLUSIONS: OCC is a rare entity, which has a tendency to be misdiagnosed. We emphasize the importance of recognizing the common features of OCC in order to aid in accurate diagnosis.
