FINE-NEEDLE ASPIRATION IN DIAGNOSIS OF METASTATIC ENDOMETRIOID ADENOCARCINOMA TO THE THYROID GLAND: A RARE ENTITY
Sumiti Gupta MD, *Renuka Verma MD, Rajnish Kalra MD and Rajeev Sen MD
Tumor metastasis to the thyroid gland is uncommon, most of these cases are discovered during an autopsy. But the number of cases seems to have increased in recent years may be related to more frequent use of fine-needle aspiration in any suspected case. In both clinical and autopsy series, renal cell, breast and lung carcinomas are the most frequent sources of metastases. They usually occur when there are metastases elsewhere, sometimes many years after the diagnosis of the original primary tumor and show poor prognosis in general. Clinical presentation with a palpable thyroid or functional disturbances in thyroid is uncommon. Metastasis of uterine cancer to the head and neck is extremely rare. Here we present a case of isolated metastasis of endometrioid adenocarcinoma to the thyroid gland diagnosed on FNAC in a 75-year-old woman presented with rapidly increasing swelling in thyroid region.
Keywords: Metastasis, thyroid gland, adenocarcinoma, endometrioid, fine-needle aspiration.
