Carcinoma cuniculatum (CC) is an extremely rare neoplasm of the oral cavity. It is essentially a well-differentiated variety of squamous cell carcinoma and shows lower metastasis risk. The histological features of CC can mimic that of papillary squamous cell carcinoma or verrucous carcinoma. CC commonly affects the plantar region of the foot, and very few cases have been described in the oral cavity. The classical histological characteristics noted are infiltration of underlying connective tissue by squamous epithelium with keratin cores and keratin-filled crypts. Herewith, we present a case of CC of the right maxilla in a young Dravidian male patient who works in a battery factory. The case presented a diagnostic challenge both clinically and histopathologically before it was completely resected using a total maxillectomy technique. The case delineates the diagnostic challenge and management of the disease.
