Background: Granular cell tumors (GCTs) are rare soft tissue lesions that can involve the female genital tract, including the vulva. Although malignant tumors are aggressive and uncommon, benign and atypical lesions still have associated risks, including recurrence and multisite development.
Cases: Four cases of pediatric vulvar GCT are presented, including 1 atypical and 3 benign tumors. The atypical lesion occurred in a 3-year-old girl, to our knowledge, the youngest reported patient with GCT of the vulva. Follow-up information is available for 3 patients, ranging 0-12 years.
Summary and conclusion: GCTs are an important differential diagnosis in patients with vulvar lesions. In the pediatric population, the tumors' risk of recurrence and multisite development require gynecologists to advocate for complete resection, careful follow-up, and thorough examination for additional tumor sites.
