<p>A rare form of squamous cell carcinoma (SCC), carcinoma cuniculatum (CC) is distinguished by its deeply infiltrative growth pattern that resembles rabbit burrows (cuniculi) along with minimal cytological atypia. Because of the “rabbit burrow” appearance, the term cuniculatum was derived from the Latin word “cuniculus,” which means burrow. It creates keratin-filled crypts as it invades the underlying tissue, which are crucial for differentiating this tumour from other types of squamous cell carcinoma (SCC). Since less than 100 head and neck cases have been documented in literature till date, hence little is known about the clinical and pathologic range of this entity. A rare and little-known form of SCC that exhibits locally aggressive behaviour is oral CC. Due to a lack of knowledge about this variant and the lack of cytologic anaplasia, CC is prone to repeated negative biopsies and incorrect diagnosis. It is therefore necessary to be aware of this clinicopathologic entity in order to properly diagnose and treat it. Therefore, this present case report describes one such case of 36-year-old male who reported to the department with the chief complaint of growth on lower left gingivobuccal sulcus, which was initially incised and given a inconclusive histopathological diagnosis, underwent repeat excision of the lesion which turned out then to be a case of Oral CC. Although the lesion has a recurrence rate of less than 20%, proper surgical excision and correct histopathological diagnosis is necessary to prevent recurrence.</p>
