Abstract
|
|
|
A case of paraganglioma of the retroperitoneum diagnosed by fine needle aspiration cytology is described.
A 60-year-old man presented with abdominal discomfort for 4 months. The smear revealed cellular between with partly rosettoid appearance. Many plexiform capillaries were distributed between the cellular sheets or encircled the cellular
nests
forming zell-ballen pattern. The tumor cells were monotonous and oval to round. The cytoplasm was amphophilic, finely granular and poorly defined. The nuclei were round and had evenly dispersed chromatin and small nucleoli. Cells
having
large or spindle nuclei were sometimes observed. The tissue sections showed typical findings of paragnglima. The cytoloqical differential diagnoses included islet cell tumor of the pancreas and carcinoid tumor. The clinical and
histoloigic findings as well as cytologic findings were helpful to confirm the diagnosis.
