case_images: Pap-stained smear slides showed numerous papillary groups of epithelioid cells in a background of lymphoid cells [Figure 1]. Psammomatous calcifications were also noted.
case_images: The Papanicolaou stain cytology smear slide shows that the epithelioid cells were relatively uniform. The cells had a high nuclear-to-cytoplasmic ratio. The nuclei were predominantly oval and exhibited fine nuclear chromatin. Quite prominent nuclear grooves and irregular nuclear membrane were also noted (x400)

case_images: The needle core biopsy showed extensive deposits of tubular and papillary groups of tumor cells with psammomatous calcification in the background of lymphoid tissue [Figure 4].

case_images: The tumor cells were immunoreactive for estrogen receptor (ER) and WT-1 [Figures 5 and 6], whereas they were nonreactive for thyroid transcription factor-1 (TTF-1) and thyroglobulin.
