최근 10년간 두피 종양에 대한 임상적 및 통계적 고찰(2004년∼2013년)

Abstract

Background: The incidence of scalp tumors has increased, despite medical advances and environmental improvement. However, few studies have reported the clinical and histopathologic features of scalp tumors. Objective: The purpose of this study was to evaluate the clinical and histopathologic features of scalp tumors. Methods: We retrospectively reviewed the clinical and histopathologic features and occurrence rates of scalpdiseases in 418 patients whose lesions were biopsied in the department of dermatology between January 2004 andDecember 2013. Results: The mean age of patients exhibiting scalp tumors was 44.9 years old. The male to female ratio was 1:0.69. The most common benign scalp tumor diagnosed was seborrheic keratosis (22.6%) followed by epidermal inclusioncyst (15.3%), intradermal nevus (8.7%), sebaceous nevus (7.1%), actinic keratosis (5.2%), pyogenic granuloma(3.0%), neurofibroma (2.5%), compound nevus (2.2%), epidermal nevus (1.1%), dermatofibroma (1.1%), and hemangioma(1.1%). The most malignant scalp tumor diagnosed was basal cell carcinoma (34.6%) followed by squamouscell carcinoma (32.7%), metastatic cancer (11.5%), angiosarcoma (7.7%), Bowen’s disease (7.7%), lymphoma (3.8%),and apocrine adenocarcinoma (1.9%). Conclusion: This study provides data on the incidence of scalp tumors. The results of our study were different fromprevious studies possibly owing to regional differences between reported patient populations. We advise physiciansto appropriately diagnose and treat scalp tumors at the earliest suspicion of malignancy.
