Abstract
Giant Fibroadenoma is commonly seen in young women. Here, we are reporting the case of an elderly lady who was diagnosed with Cystosarcoma Phylloides clinically and by FNAC. Simple mastectomy was performed and histopathology revealed a Giant Fibroadenoma. This report focuses on the rarity of the age of presentation, confusing clinical features, role of FNAC and histopathology, the need to differentiate them and the modalities of treatment.
