A Neglected Case of a Benign Phyllodes Tumor Presenting as a 10.5 kg Breast Mass

Phyllodes tumor is a type of fibroepithelial neoplasm involving the breast. This tumor is rarely reported in adolescents and the elderly and has a peak incidence in middle-aged women. Histologically, phyllodes tumors are classified as benign, borderline, or malignant. Phyllodes tumor though rare can mimic breast carcinoma and can grow rapidly to massive size. Hence, carcinoma breast should always be kept as a differential diagnosis. Phyllodes tumors can present in different sizes and consistency. Giant forms can lead to postural deformities and back pain. There can be associated skin changes and ulceration due to pressure necrosis. Core needle biopsy is mandatory for the confirmation of diagnosis. It helps in decision-making for further management of the tumor. There is always a risk of recurrence in these tumors. An adequate resection margin is required to avoid any chances of relapse. Most of the phyllodes tumors do not have lymph node metastases and they rarely spread. However early and prompt surgical management is needed to avoid any possibility of malignant transformation. Here we report a neglected case of phyllodes tumor in a 68-year-old tribal woman with a huge left breast mass for 12 years.
