Squamous cell carcinoma is a common malignant condition affecting the oral cavity and may involve the surrounding maxillofacial regions. Treatment commonly involves resection of the tumor, followed by prosthetic rehabilitation of the resection defect. This clinical report presents a 62-year-old Asian male patient who had previously undergone surgical resection, resulting in a post-surgical Aramany Class II maxillary defect. The patient\'s medical history included severe trismus, characterized by restricted mouth opening, as well as a diagnosis of maxillary sinus verrucous squamous cell carcinoma. This report provides a comprehensive account of the rapid fabrication of an interim obturator using digitally assisted dentistry techniques.

The advent of tissue engineering and the clinical applications with cultured epidermal autograft (CEA) have improved the prognosis of severely burned patients. Marjolin ulcers (MUs) are a well-known complication of burns. These malignant neoplasm transformations of burn scars are usually squamous cell carcinomas with a higher incidence of regional metastases. Radical surgery remains the treatment of choice. To identify cases of malignant transformation occurring at sites of CEA in a cohort of 68 massively burned patients. A retrospective single-centre study was performed from April 2017 to June 2019 at the Military Hospital of Clamart (France). A total of 34 patients treated between 1991 and 2013 (including one post-mortem) were included. Four cases of squamous cell carcinoma occurred in areas previously covered by CEA. The data from clinical and histopathological examination as well as treatment modalities are presented. One patient died as a result of the evolution of his squamous cell carcinoma, and two others required salvage amputation due to locoregional recurrence. The prevalence of these CEA-MUs is estimated at between 5.9% and 11.7% and the person-time incidence rate of CEA-related MUs is about 5.9 per 1,000 persons-years. In our study, the average time to malignant transformation seems considerably shortened (32-35 years for \"classic burn MU\" versus 15.7 years for CEA-MU). This first documented case series of CEA-MUs demonstrates the need to inform caregivers and educate patients. Further studies are needed to specify the true incidence of CEA-graft site malignancy.

Although the majority of laryngeal malignancies are the conventional squamous cell carcinomas (SCC), a wide variety of malignant epithelial tumors can affect the larynx. Current treatment guidelines are designed to guide clinicians in management of conventional laryngeal SCC. Less is known about the biological behavior and responsiveness to therapy and overall outcomes of other malignant epithelial lesions. Because a spectrum of disease biology is represented by these rare phenotypes, an understanding of the basic biology can help direct management to optimize clinical outcome in this group of patients. This review provides a critical analysis of literature relating to the diagnosis, management, and outcome of patients with non-conventional squamous malignant epithelial neoplasms of the larynx. Particular attention is paid to features which are at variance with the conventional SCC and how these impact on management of these rare tumors.

OBJECTIVE: Verrucous carcinoma of the larynx (VCL) is a rare entity with reportedly favorable prognosis. Current analyses are limited primarily to case reports and case series, thus making a population-based analysis useful in characterizing frequency, incidence, and survival trends to guide clinical diagnosis and decision making.
METHODS: Analysis of the National Cancer Institute\'s SEER (Surveillance, Epidemiology, and End Results) database.
METHODS: Cases of VCL diagnosed between 1973 and 2011 were searched in the SEER database. Analysis was carried out with respect to patient demographics, tumor characteristics, incidence, treatment modality, and survival.
RESULTS: In sum, 516 patients with VCL were identified. Males composed 88.4% of cases. Whites accounted for 88.4% of cases, with 8.1% of cases occurring in black patients. Most cases (79.7%) arose in the glottis, a statistically significant predilection when compared with other laryngeal malignancies (P < .0001). Incidence of VCL decreased from 2000 to 2011, with an annual percent change of -5.4%. Overall 1-, 5-, and 10-year disease-specific survival for VCL was 97.5%, 88.0%, and 77.4%, while 1-, 5-, and 10-year relative survival was 98.1%, 85.5%, and 74.2%, respectively. Surgery seemed to confer better prognosis when compared with other treatment modalities.
CONCLUSIONS: This large population-based analysis of VCL demonstrates that this entity has a good prognosis, arises in the glottis, and is decreasing in incidence. Five-year survival seems highest when surgery is utilized. However, this finding may be subject to selection bias in high-stage lesions.
