Background: There is little clinical analysis of benign and malignant neoplasms in genital skin in Korea.
Objectives: This study was to investigate clinical features and proportion of neoplasms occurring in genital skin.
Methods: We retrospectively reviewed all patients with tumors located on genital skin from 2010-2019. The patients were divided into 19 benign and 9 malignant tumor categories.
Results: A total 366 were analyzed, including 178 (48.3%) patients with benign neoplasm and 188 (51.4%) with malignant neoplasm. The mean age was 58.2 years and 56.8% of patients were male. 191 patients (52.2%) showed no symptoms The most common benign neoplasm was bowenoid papulosis (n = 49), followed by seborrheic keratosis (n = 33), epidermal cyst & steatocystoma multiplex (n = 28), melanocytic nevus (n = 18), and angiokeratoma (n = 17). The most common malignant neoplasm was extramammary Paget’s disease (EMPD) (n = 68), followed by squamous cell carcinoma (n = 54), squamous cell carcinoma in situ (n = 28), basal cell carcinoma (n = 12) and malignant melanoma (n = 11). The most common benign and malignant neoplasm was epidermal cyst and squamous cell carcinoma in female, and bowenoid papulosis and EMPD in male, respectively. Each neoplasm showed specific predilection location.
Conclusion: This study would be useful evidence and information in dermatological practice.
