The @entity11469 ( @entity157 ) is distinguished from other @entity157 ( @entity157 ) by its unique clinical and pathologic features. Cytological features for this @entity5 on fine needle aspiration (FNA) of @entity5 have been described earlier. We present here a unique case of metastatic @entity157 diagnosed by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of mediastinal adenopathy. A 32-year-old @entity1 with a history of oral contraceptive use presented with @entity390 and severe @entity490 but no ascites or stigmata of @entity82 . She had a past history of resection of a @entity409 . Serial computed tomography scans revealed @entity3329 and the @entity1 was referred for endoscopic ultrasound (EUS). A transesophageal EUS-FNA was performed and tissue was collected for cytological evaluation by an on-site pathologist with no knowledge of prior history. Based on morphology correlated with prior history received later, a final diagnosis of metastatic @entity157 in the retrocardiac lymph node was rendered on the EUS-FNA samples. There are very few reports in the literature where a diagnosis of @entity157 is rendered at unusual sites. This case highlights that EUS-FNA is a relatively non-invasive, rapid, accurate and effective modality in obtaining tissue from otherwise hard-to-reach areas. It also suggests that metastasis of @entity157 can be observed in mediastinal nodes and that diagnosis based on cytological features can be rendered even when the @entity5 is identified at unusual locations.
