Squamous Cell Carcinoma of the Face in Black Skin: A Serie of 27 Cases in the Dermatology Department of Aristide Le Dantec Teaching Hospital - Abstract
Background: In black-skinned patients, cutaneous squamous cell carcinoma (SCC) occur mainly in the lower limbs, a site with minimal sun exposure. The particularities of the involvement of these tumors on the face, highly attempt by sun radiation are unknowed. Objectives: To identify the epidemiological and anatomo-clinical profile of squamous cell carcinomas of the face in patienst with black skin. Methods: We conducted a retrospective study (from January 1996 to October 2016) of patients with a cutaneous SCC followed in the dermatology department of Aristide Le Dantec Teaching Hospital. Among them, we identified the epidemiological and anatomo-clinical features of the face localization. The data were pooled through Sphinx software and processed by epi-info 7.2. Results: One hundred and twenty-two patients (n=122), 16 men and 11 women, with cutaneous SCC were enrolled. Face involvement corresponding to our sample represented 21.3% (27 cases), accounting for 54% of all cancers of this topography. The mean age of patients was 52 years. The tumor was located on the cheek in 37% (n=10), on the lower lip in 37% (n=10), and on the ears and the eyelids in 11.1% (n=3) each. The nose and the upper lip were involved in 7.4% (n=2) respectively. Pre-existing dermatosis was reported in 14 patients. We noted 7 genodermatoses and 7 acquired dermatoses. Conclusion: In dark-skinned patients, squamous cell carcinoma remains the most common facial skin cancer and mainly occurs on the lower lip and cheeks.
