Leiomyoma is a mesenchymal tumor which arise from any structure or organ containing smooth muscle, but is frequently seen in the female genital tract. Renal leiomyoma is extremely rare benign lesion with low incidence (1:1000), has been reported mostly in adults and very few cases have been described in the pediatric age-group. It is often asymptomatic and can be diagnosed when reaches large sizes. Hereby, we present a case of renal leiomyoma in a smaller size, in the pediatric age group. •Renal leiomyoma is extremely rare benign lesion in the pediatric age.•Leiomyoma may rarely arise from almost every part of the genitourinary system.•Leiomyoma must be considered in differential diagnosis of benign-looking renal mass.•Definitive diagnosis requires histological examination.
