An 18 year old female presented with the history of pain in abdomen, breast engorge-ment, swelling over both legs and breathless-ness for three month. On clinical examination diagnosis of fibroadenoma breast was made. Ultrasonography of abdomen showed bilateral ovarian mass. Bilateral salpingo-ophrectomy was done and specimen was sent for histologi-cal examination. Two lobulated solid masses of tissues the larger one measuring 13¥8¥5 cm and smaller one measuring 10¥7¥5 cm in size received. Microscopic examination showed monomorphic population of discohesive, hyperchromatic small round cells had high N:C ratio, coarse chromatin, conspicuous nucleoli and scant to moderate amount of basophilic cytoplasm, lying in sheets and separated by fibrous strands and diffusely infiltrating the ovarian stroma. Fine needle aspiration from breast lump and leg swelling showed predomi-nant population of blast cells. Myeloperoxidase was strongly positive and diagnosis of granulo-cytic sarcoma was confirmed
