Phyllodes tumour of the breast, earlier called cystosarcomaphyllodes, is a rare fibroepithelial breast neoplasm that occurs in all age groups from adolescents to elderly. Phyllodes tumour occurring during pregnancy and associated with lactating breast is extremely rare. Giant phyllodes tumours or giant fibroadenomas are those measuring more than 10 cms in diameter and weighing more than 500 gm. Phyllodes tumour typically exhibits an exclusive intracanalicular growth pattern of fibroepithelial cells with classical, deep leaf-like stromal projections into dilated lumens from which its name “phyllodes” is derived. A 32-year-old primigravida at 38 weeks of gestation, presented with massive and heavy swelling of the left breast, growing over the last eight months. Physical examination revealed a massively enlarged left breast with palpable, firm, nodular mass measuring 10 x 20 cm and occupying whole of the left breast. A trucut biopsy demonstrated a fibroepithelial lesion suggestive of benign phyllodes tumour. Simple mastectomy was performed six days after the delivery of the baby by caesarean section. The histopathological report confirmed the diagnosis as benign phyllodes tumour with ductal hyperplasia and no atypia. We are reporting this case because of its massive size, associated with lactating breast and difficulty in histopathological differentiation from Giant fibroadenoma.
