The diagnosis is usually confirmed by histopathology. Most of GCTs are benign, but some lesions may exhibit malignant criteria. This study is a retrospective case series including all children with histopathologically documented multiple GCTs who attended the dermatology department of the university hospitals between February 2008 and March 2021. The objective of our study was to raise awareness to this unrecognized and rare entity in such age group. The study included 9 patients (6 girls and 3 boys) with multiple GCTs. Their age ranged between 5 and 13 years. The lesions were skin-colored to light brown, firm, smooth-surfaced nodules. Most of the lesions were on the extremities, and their mean diameter was 160.5 mm2. None of the lesions exhibited any malignant criteria on histopathology. No extracutaneous or mucosal lesions were detected. Dermatologists should be aware of this rare condition in children because early recognition allows more conservative resection of the tumor and less invasive reconstruction of the defect. Our study highlights that multifocality does not necessarily indicate malignancy or other systemic comorbidities. Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.
