Papid Growing Fibroadenoma in an Adlescent

Area of Science:

• Oncology
• Endocrinology
• Pathology

Background:

• Fibroadenomas are common benign breast tumors, particularly in young women.
• Rapid growth of fibroadenomas can cause patient concern and necessitate intervention.

Purpose of the Study:

• To report a case of rapidly growing fibroadenoma in a pediatric patient.
• To investigate the potential factors contributing to the accelerated tumor growth.

Main Methods:

• Clinical examination and ultrasound for initial diagnosis.
• Surgical excision (lumpectomy) for tumor removal.
• Histopathological analysis and immunohistochemical staining for estrogen receptor expression.

Main Results:

• A 13-year-old girl presented with a rapidly enlarging left breast mass.
• The fibroadenoma increased 50% in volume over four months, correlating with menstrual cycles.
• Immunohistochemistry confirmed positive estrogen receptor staining in glandular epithelial cells of the fibroadenoma.

Conclusions:

• The estrogen sensitivity of the fibroadenoma is a likely cause of its rapid growth.
• This case highlights the importance of considering hormonal influences in benign breast tumor behavior.
