Objective: To describe the clinical characteristics of contact dermatitis patients examined and treated at Thai Binh Dermatology Hospital, Facility 1, in 2021. Method: A cross-sectional descriptive study of 52 contact dermatitis patients examined and treated at Thai Binh Dermatology Hospital, Facility 1, from March 2021 to September 2021. Results: The most common site of contact dermatitis was the face (65.4%). The highest proportion of disease duration was less than 15 days (44.2%). The most frequently reported symptom was itching (86.5%). Contact dermatitis was predominantly observed in female patients (76.9%). The most affected age group was 15–29 years (26.9%). The most common occupational group affected was freelancers (26.9%), while retirees had the lowest incidence (1.9%). The leading cause of contact dermatitis was cosmetics (50%), whereas dyes and fabric finishing agents accounted for the lowest percentage (1.9%). The most common skin lesions were erythema (86.5%), followed by scaling (46.2%). There was a significant difference between irritant contact dermatitis and allergic contact dermatitis, with allergic contact dermatitis being more prevalent (76.9%). Conclusion: The clinical characteristics of contact dermatitis are diverse and unevenly distributed across gender, age, occupation, and causative allergens. The findings provide a foundation for developing appropriate and effective treatment strategies to reduce recurrence and improve patient care.
