Giant Malignant Phyllodes Tumour of Breast- A Clinical Dilemma and Surgical Challenge

Abstract

Phyllodes tumour is an uncommon tumour of the breast. It is fibroepithelial in origin and mostly benign. Giant phyllodes tumours are described as tumours with size more than 10 cm and are extremely rare. Differentiating malignant and benign tumours pathologically is difficult and needs clinical judgement and high index of suspicion. A 50-year-old female presented with complaint of swelling in the left breast. On further evaluation, it was diagnosed as phyllodes tumour on biopsy. She underwent left mastectomy and excision of pectoralis major muscle due to clinical and radiological suspicion of malignancy. Postoperative histopathology report revealed malignant phyllodes tumour. Cases of giant phyllodes tumour should undergo adequate imaging and image guided biopsy with high index for suspicion for malignancy. They should be operated as per the principles of oncosurgery as there is a high probability of such huge tumours harboring malignancy.
