Fine needle aspiration biopsy cytology in the diagnosis of inflammatory lesions.
In 42 fine needle aspirations (FNA), the cytologic findings were interpreted as either suppurative or granulomatous inflammation. The majority of these FNAs were performed in patients with a known history of malignancy in whom recurrent or residual malignancy was suspected clinically. In 13 cases, a specific microbiologic diagnosis was made on the basis of the aspirate, either by cytology or by culture. In the remaining 29 cases, no specific diagnosis was possible. Open biopsies were later performed in 9 of the 29 cases, revealing the presence of actinomycosis of the parotid in one case and of carcinoma of the breast in a second. Five additional patients in whom only inflammation was diagnosed on the aspirate subsequently proved to have tumor at the FNA site. FNA therefore is not absolutely reliable for the exclusion of malignancy and requires correlation with other data and appropriate follow-up. Aspiration did, however, rapidly provide solutions to otherwise confusing clinical problems in the majority of instances.
