- Abstract
Objective To gather all patients with squamous cell carcinoma and try to classify them according to their triggering factors. Methods This is a cross-sectional study that was carried out during the period from 2014-2023 where all patients with squamous cell carcinoma were collected and analyzed into groups according to their triggering factors. Nearly all patients were Fitzpatrick skin type III and IV. Full demographic and clinical data were studied and evaluated. A histopathological assessment was done as a confirmatory measure. Results Full analysis and evaluation were carried out for 95 cases of squamous cell carcinoma and classified into the following groups: lower lip sunlight-induced SCC in 44 (46.3%) cases, ordinary SCC without triggering factor in 22 (23.1%), lichen planus induced SCC in 17 (17.89%) and burninduced in 12 (12.63%) patients with SCC. Conclusion Cutaneous squamous cell carcinoma is not a common tumor but is frequently triggered by sunlight exposure, lichen planus and old burn scar.
