Abstract
Oral Carcinoma cuniculatum(OCC) is rare variant of squamous cell carcinoma. The histopathological features of this type of carcinoma makes it special in the literature of Pathology. The appearance of deep invading epithelial islands with pool of keratin cores very similar to rabbit burrows gives the term cuniculatum to the carcinoma. Here we present a case of OCC on the lateral surface of the tongue. Early diagnosis of such case is very important to distinguish it distinctly from the other entities of squamous cell carcinoma like verrucous carcinoma. The knowledge of existence of such entity of squamous cell carcinoma occurring in the oral cavity is very important to facilitate correct treatment planning and management.

Abstract
We report on a case of carcinoma cuniculatum (CC) of the maxillary gingival mucosa. A 60-year-old woman presented with an exophytic gingivo-palatal mass with slow growth and osteolytic evolution. A first performed biopsy was negative for malignancy. The diagnosis of CC was established on the surgical representative biopsy. CC is a rare low-grade variant of squamous cell carcinoma that is usually found in the foot or in oral cavity. The pathognomonic microscopic feature of CC is an endo- and/or exophytic lesion composed by a well differentiated squamous epithelium infiltrating into underlying stroma forming a complex pattern of keratin cores and keratin filled "rabbit warren" crypts. CC is a locally evolutive carcinoma with a usually good prognosis usually without lymph node or distant metastatic evolution.

Abstract
Purpose Oral carcinoma cuniculatum is a rare well-differentiated variant of oral squamous cell carcinoma. The purpose was to systematically review its unique features to differentiate it from other variants as verrucous carcinoma, papillary squamous cell carcinoma and well-differentiated squamous cell carcinoma. Materials and Methods A systematic review was performed using MEDLINE, Dentistry and Oral Sciences Source and PubMed databases and any existing articles related to the research subject missed in the search strategy to screen ones reporting cases occurring exclusively in the oral cavity in English literature. Variables analyzed included clinical, etiologic, imaging, histopatholgical features, treatment, follow-up and survival rates. Results From 229 hits, 17 articles with 43 cases were included in the systematic review. Clinically it showed a female predilection with pain and/or ulceration of a relatively long duration and exudation being the most common symptoms. Histologically, it showed more endophytic features comprising well-differentiated squamous epithelium with absent or minimal cytological atypia and multiple keratin filled crypts or cuniculus. Inflammatory stromal reaction and discharging abscesses were reported in most of the cases. Bone destruction was predominant in most imaging features. Complete surgical resection with a safety margin was the treatment of choice in most of the cases with few recorded recurrence cases. Conclusion Apprehensive knowledge of oral carcinoma cuniculatum unique features is essential to avoid its misdiagnosis and provide proper treatment especially for recurrent cases.

Abstract
Squamous cell carcinoma (SCC) is the second most common type of skin cancer after basal cell carcinoma (BCC). The overall prevalence of BCC is 3 times higher than that of SCC, but this can vary when looking at specific locations such as the hand, where SCC is much more common than BCC. Carcinoma (or epithelioma) cuniculatum is a rare variant of SCC. It was originally described as a verrucous carcinoma of the soles. Exceptionally, it can arise in other parts of the skin. We report a rare case of carcinoma cuniculatum of the right thenar region with bone and lymph node involvement.

Abstract
Carcinoma cuniculatum (CC) is a rare variant of squamous cell carcinoma first described in 1954. Cases of CC in the head and neck are exceedingly rare, with 66 cases reported since 1977. These tumors are generally low-grade, well-differentiated and locally aggressive malignancies. Patients are often subjected to a long period of misdiagnoses given the clinical similarity of these entities to odontogenic cysts and abscesses. We report a case of a carcinoma cuniculatum of the mandible with very advanced local involvement of disease, highlighting the unusual characteristics of this rare tumor that are important for clinicians to recognize. Clinical presentation, histology, risk factors, treatment options, and prognosis are also reviewed.

Abstract
Carcinoma cuniculatum (CC), a rare, well-differentiated variant of squamous cell carcinoma, is uncommon in head and neck sites but when it does occur is most common in the oral cavity. Here we report a rare case of CC involving the larynx. A 49-year-old man presented with 10 months of worsening hoarseness and, despite multiple biopsies, no diagnosis of malignancy could be established. Eventual partial excision of the lesion and histologic review of prior specimens confirmed the diagnosis of CC. Focally, a transition to respiratory epithelium indicated the presence of an associated saccular cyst. Total laryngectomy was performed and 6 months later the patient is free of disease. Only two prior cases of CC have been reported in the larynx. Diagnosis of CC is challenging given the low grade histologic features and awareness of this entity for both treating physicians and the pathologist is important to reach a diagnosis of malignancy. This case highlights the challenges in diagnosis of CC, especially in unusual locations and when associated with other lesions such as a saccular cyst. Awareness of this rare tumor type combined with close communication between treating clinicians, radiologists and pathologists should allow earlier diagnosis and treatment.

Abstract
Carcinoma cuniculatum (CC) is a rare, distinct clinico-pathological variant of squamous cell carcinoma (SCC) that is defined histologically by the characteristic infiltrative pattern of a deep, broad, and complex proliferation of stratified squamous epithelium with keratin cores and keratin-filled crypts. Herein, we present a case report of CC of the oral tongue and discuss its diagnosis, management, and outcome, as well as briefly review the world literature. To our knowledge, this is the first documented case of CC of the tongue to be reported in the English literature. We draw attention to its clinico-pathological features and highlight that awareness of this entity as a distinct variant of SCC facilitates its correct management.
