Ovarian cyst form 40 years old lady. it was 18 C.M in diameter, unilocular and filled with serous fluid.
on Aspirate you can see :
– Simple columnar epithelium ( the red spindly cells ” lets say pseudo-spindly always remember this is not a cross section “).
– the dispersed round cells in between on might think they may represent the intercalated cells and then the diagnosis will be serous cyst But at high magnification you will see that they are full of foamy mucin with pushed nucleus typical of goblet cells.
– the foamy macrophages ” last pic ” indicating the cystic nature of this aspirate
so we have 2 components the serous and mucinous and the proper diagnosis will be seromucinous cyst
please note that we can’t commet on the malignancy of such neoplasm unless we have H & E sections to asses invasion
