It had then progressed to current size involving the whole breast with dull aching pain. On Inspection there was a lump of 25 x 25 cm involving whole of breast. The overlying skin was tense, shiny, visible dilated veins present. No visible discharge, ulceration, overlying skin is erythematous and striae were present over lump. On palpation temperature of the left breast was raised slightly. Breast tissues were not felt separately from the lump. The lump was involving overlying skin but not the underlying pectoralis muscle. On pressing the lump, no nipple discharge was present. It was oval in shape, had irregular surface with soft to firm areas in between. The consistency was firm to hard. After clinical history, general physical and local examination, provisional diagnosis of phyllodes tumor was made. Biochemical Investigations were within normal limits.  On Trucut biopsy of left breast, histo-pathological features were suggestive of fibroepithelial tumors and on imprint smear cyto-morphologic features were suggestive of ductal carcinoma left breast lump. On mammography bilateral breast, a large rounded ill defined mass occupying all of the quadrants of left breast with a radio-lucent halo. Diagnosis of phyllodes tumor (BIRADS IV) b left breast and BIRADS I right breast was made. Patient was admitted in surgery ward and total left mastectomy was done. The patient had an uneventful recovery. She was free of recurrence 3 months after surgery. We concluded that accurate preoperative pathological diagnosis is very important for management of phyllodes tumor, and allows correct surgical planning and avoidance of reoperation.
