Caucasian Skin Under Tropical Sun: A Case Series of Nonmelanoma Skin Tumors

Background: Skin tumors, particularly nonmelanoma skin tumors (NMSTs), are a growing global concern. While the incidence is well-documented in populations with fair skin, limited research explores NMST in diverse populations. Aims: This case series aims to study the clinical profile and management of premalignant and malignant NMSTs among Caucasians residing in South India. Methods: This was a retrospective observational study. All Caucasian patients diagnosed to have NMSTs in our outpatient department over a period of 5 years were identified. Their clinical details and histopathology reports were reviewed. A total of 76 patients were taken up for final analysis. Results: The median age of the study population was 64 years, consisting of 49 males and 27 females. Actinic keratosis was observed in 57 patients, while 19 presented with malignant skin tumors, including basal cell carcinoma, keratoacanthoma, and squamous cell carcinoma. The majority of lesions were found in sun-exposed areas. Actinic keratoses were mostly treated using cryotherapy, while the malignant skin tumors were surgically excised. Conclusion: Caucasians in South India exhibit a notable incidence of premalignant and malignant NMSTs, underscoring the necessity for heightened vigilance and preventive strategies. Dermatologists play a pivotal role in raising awareness and implementing effective measures for the diverse populations residing in tropical regions.
