BACKGROUND: @entity765 have a tendency to recur locally, and traditionally they have been treated surgically. No treatment is sometimes indicated, however; this requires a morphological diagnosis that is not based on a surgical specimen. In this study we aimed to identify the diagnostic accuracy of needle and core biopsy for the morphological diagnosis of desmoid. METHODS: We compared the diagnostic accuracy of fine-needle aspiration (FNA) and core needle biopsy (CNB) in 69 and 26 @entity1 , respectively, who had had surgical resections for desmoid. We also reviewed 15 additional cases that had been incorrectly diagnosed as desmoid on FNA but which had different diagnoses after surgery. RESULTS: FNA-based diagnoses of desmoid/ @entity81 were rendered in 35 of 69 cases, and other benign spindle cell proliferations in 26 cases and spindle cell sarcoma in the remaining 4 cases. All 26 CNBs were either suggested to correspond to desmoid (24) or other benign spindle cell lesions (2). Of the 15 FNAs incorrectly diagnosed as desmoid, 2 were found to be @entity242 . INTERPRETATION: FNA is fairly reliable for recognition of the benign nature of desmoids. Occasional over- and under-diagnosis of @entity5 can occur, however. CNB appears to be more reliable.
