Fine needle aspiration cytologic findings and differential diagnosis of solitary pseudorheumatoid nodule.
The cytologic findings in fine needle aspirates of two solitary pseudorheumatoid nodules are presented. The main characteristic of the smears was a necrotic granular and filamentous background accompanied by a granulomatous inflammatory infiltrate. The differential diagnosis is analyzed. The results in these cases indicate that the diagnosis of a solitary pseudorheumatoid nodule may be made by fine needle aspiration cytology after a critical evaluation of the cytologic and clinical data and with the help of special stains and microbial culture.
