Uncommon vulvar findings in children and adolescents referred to a tertiary center over 14 years:a retrospective study and review of the literature

Abstract

Background and Purpose: Vulvar complaints are particularly common among children and adolescents; the etiologies largely depend on patient age. Most clinicians are not familiar with the normal variations of the female external genitalia, and this results in many unnecessary referrals. The aim of this study was to describe the frequencies of uncommon vulvar findings (other than ambiguous genitalia or vulvovaginitis) in children and adolescents examined in a tertiary referral center over a 14-year period.|
Methods: Records of girls (ranging from newborns up to the age of 18 years) who attended a tertiary Pediatric-Adolescent Gynecology and Reconstructive Surgery Center with vulvovag-inal complaints during the period 2004-2017 were studied retrospectively. Patient age, rea-son for referral, presenting complaints, key aspects of clinical examination, diagnosis and management were recorded for each patient. 
Results: A total of 67 females (37 adolescents and 30 children) were included in the study. Labial minora hypertrophy and labial adhesions were the most common findings in 18 (26.9%) and 17 (25.4%) of the cases, respectively. Less common diagnoses were genital warts in 7 (10.4%) patients, genital trauma in 5 (7.5%) patients, labia minora masses in 5 (7.5%) adolescents, and unilateral labial majora inflammation in 2 (3%) patients. Among the adolescents with labia minora masses, three were diagnosed with vascular malfor-mations, one patient underwent cyst removal, and one suffered labial minora inflammation. Other rare diagnoses included stenosis of the vaginal opening secondary to lichen sclerosus in 1 (1.5%) adolescent and extensive unilateral hemangioma of the vulva in 1 (1.5%) 15-month-old child. Finally, in 11 (16.4%) girls, no pathology was identified.|
Conclusions: Comprehensive external genitalia examination is an important part of periodic health checks in girls (children and adolescents).
