Abstract
BACKGROUND

A giant juvenile fibroadenoma (GJF) is a rare, benign breast tumor that affects females < 18 years of age. GJFs are generally suspected based on a palpable mass. GJFs influence breast shape and mammary gland development via the pressure effect from their enormous size.

CASE SUMMARY

Herein we report a case involving a 14-year-old Chinese female with a GJF in the left breast. GJF is a rare, benign breast tumor that usually occurs between 9 and 18 years of age and accounts for 0.5%-4.0% of all fibroadenomas. In severe cases, breast deformation may occur. This disease is rarely reported in Chinese people and has a high clinical misdiagnosis rate due to the absence of specific imaging features. On July 25, 2022, a patient with a GJF was admitted to the First Affiliated Hospital of Dali University. The preoperative clinical examination and conventional ultrasound diagnosis needed further clarification. The mass was shown to be an atypical lobulated mass during the operation and confirmed to be a GJF based on pathologic examination.

CONCLUSION

GJF is also a rare, benign breast tumor in Chinese women. Evaluation of such masses consists of a physical examination, radiography, ultrasonography, computer tomography, and magnetic resonance imaging. GJFs are confirmed by histopathologic examination. Mastectomy is not selected when the patient benefits from a complete resection of the mass with breast reconstruction and an uneventful recovery.

Keywords: Giant juvenile fibroadenoma, Fibroadenoma, Breast tumor, Ultrasonography, Case report

Core Tip: Giant juvenile fibroadenoma (GJF) is a rare benign breast tumor below 18 years of age and can be suspected mainly through palpable masses in clinical practice. Breast ultrasonography shows left masses > 5 cm with benign features (Breast Imaging Reporting and Data System score 3) through the preferred examination for breast imaging in this GJF case. The breast mass of GJF patients in this report showed a lobulated shape and many lobular ducts. Therefore, it is necessary to differentiate GJF from phosphotyrosine binding by histopathology. Clinicians should be aware of this diagnosis for a better approach and early conservative treatment instead of blindly performing mastectomy.
