Giant juvenile fibroadenoma in a 15-year-old Nigerian female: A case report with review of literature

Introduction Breast mases in female adolescents are rare and consist mainly of developmental lesions and benign tumours.1 The benign tumours seen are mostly fibroadenoma which is the most common breast tumour seen in adolescent females.2 It may present as solitary or multicentric tumour.3 It may also vary in size and is designated as giant juvenile fibroadenoma “GJF” if it is greater than 5cm, 500g or replaces at least 80% of the breast tissue.3 GJF accounts for 1-8% of breast lesions in the adolescent population.3,4 Overall, giant fibroadenoma accounts for 0.5-2% of all fibroadenomas.4 We present a case of GJF in a 15-year-old female who was managed in our clinical setting.
