Oral Carcinoma Cuniculatum: A Case Report

Abstract

We report a case a of oral carcinoma cuniculatum, an exophytic variant of oral squamous cell carcinoma that has bland cytomorphologic features, and a peculiar and characteristic growth pattern. Despite the lack of cytologic atypia, the tumor exhibited locally aggressive and infiltrative behavior with bone and cutaneous involvement. Pertinent benign and malignant mimics, and helpful differentiating features are also discussed.
