Analysis of oral and maxillofacial pathology lesions over an 18‐year period diagnosed at Kuwait University

Abstract

Aims The aim of the present study was to determine the range, frequency, prevalence, and distribution of oral lesions submitted for histopathological diagnosis at the oral pathology laboratory at Kuwait University. Methods A retrospective analysis was conducted of all cases submitted to the oral pathology laboratory over an 18‐year period. Age, sex, histopathological diagnosis, and location of the lesions were recorded. Lesions were classified into 10 diagnostic categories. Results Of the 697 biopsies examined, the average age of the patients ranged from 1 to 93 years with a mean age of 37.83 ± 16.62 (mean ± SD). The most common diagnostic category was mucosal pathologies (N = 205, 29.4%), followed by odontogenic cysts (N = 158, 22.7%) and reactive lesions (N = 97, 13.9%). The three most common histopathological diagnoses were hyperkeratosis (N = 70), dentigerous cyst (N = 48), and mucocele (N = 44). Twenty‐five malignant neoplasms were diagnosed, the majority of them in males. A significant association was observed between age and the group of lesions of the oral cavity (P ≤ 0.001). Conclusions The present study provides the first set of data from Kuwait that covers a wide range of oral lesions. Mucosal pathologies were the most frequently diagnosed lesions and the majority of diagnoses were benign.

Diagnóstico histopatológico de lesiones orales de la mesorregión agreste del estado de Pernambuco

“…Entre as neoplasias malignas diagnosticadas, o carcinoma epidermóide foi a lesão mais prevalente, responsável por 91% dos casos. Resultados que corroboram os encontrados em outros estudos similares (2,10,14,15,(17)(18)(19)20). Este dado chama a atenção porque, apesar das limitações do estudo, foi possível encontrar um número significativo de casos, o que demonstra a necessidade de mais políticas públicas que atinjam o interior sobre prevenção do câncer oral e consumo de tabaco e álcool.…”

Oro-facial malignancy in north of Iraq: a retrospective study of biopsied cases

“…A limited number of studies were conducted in different Middle East countries regarding histopathologically confirmed orofacial lesions, and few studies estimated oral malignancies relative frequency [6][7][8][9][10][11][12][13][14]. Oral squamous cell carcinoma (OSCC) is the commonest oral malignancy.…”

Evaluation of cysts and odontogenic tumors over a period of 8 years in a reference medical hospital in Brazil

“…Additionally, identifying the frequency of oral and maxillofacial lesions is essential for establishing the diagnosis and treatment of the patient. (Joseph et al, 2019); knowledge of the location, age, and gender predilections of different diseases of the oral cavity is useful with regard to determining their demographic data; and, finally, it is essential for the planning and execution of public health programs. (Alhindi et al, 2019).…”
