ovarian dermoid cyst 500x H&E staining, detail view showing the cross section of hairs, and of the foreign body giant cell.

The radiologist informed that a hair came out from the needle while preparing the smears... This and the benign squamous cells, both anucleated and nucleated, point to the confirmed diagnosis of mature teratoma, or ovarian dermoid cyst. The other ovary showed also a benign teratoma, but with some less mature areas.
