Giant fibroadenoma presenting like fungating breast cancer in a Nigerian teenager

Background:Giant fibroadenoma of the breast is a rare benign breast tumour which seldom grows to a giant size, it is even rarer for this benign tumour to grow rapidly, ulcerate spontaneously and present like a fungating breast tumour in a way mimicking breast cancer.
Case Presentation:This is a presentation of a 14 year old premenarchal girl with a massive ulcerating and fungating left breast mass that was initially thought to be a fungating locally advanced breast carcinoma on clinical examination. Further examination of the morphology of the resected surgical specimen and histological examination confirmed it to be giant fibroadenoma of the breast. It was successfully managed by partial mastectomy and breast reconstruction with an excellent result and a high degree of patient satisfaction was achieved.
Conclusion:Though a rare clinical entity benign breast tumour can present like a fungating breast cancer and this must be bore in mind especially in young adolescent patients presenting with ulcerating breast tumour.
