Cytomorphologic features of XXXX : a comparative study.

@entity511 @entity5 @entity83 @entity705 @entity421 @entity84 @entity81
OBJECTIVE: To perform a comparative analysis of fine needle aspiration cytology (FNAC) features of @entity5 and their significance in diagnosis. STUDY DESIGN: A retrospective evaluation of 17 @entity5 diagnosed by FNAC was done. Cytologic features were detailed and compared among different @entity5 types and with available histology. RESULTS: The 17 cases comprised @entity83 (5), @entity705 (1), @entity84 (2), @entity511 (7). @entity84 and chondromyxoid @entity81 were specifically diagnosed in all 4 cases by FNAC due to characteristic cytology. However, the cytologic appearance of @entity83 overlapped significantly with that of well-differentiated @entity511 , but the correct diagnosis was made by interpreting cytology with clinicoradiologic correlation. The cytologic features of high chondroid fragment cellularity, irregular cell arrangement in fragments, prominent nucleoli, and moderate to severe nuclear hyperchromasia and mitotic activity were limited to @entity511 . The single error consisted of a case of @entity421 , chondroblastic type, that was interpreted as @entity511 . CONCLUSION: FNAC smears interpreted in the light of clinical and radiologic findings demonstrated high diagnostic accuracy. It is important to be aware of the cytology of uncommon @entity5 such as @entity84 and chondromyxoid @entity81 as well as of the overlap of cytologic features between @entity83 and @entity511 to avoid diagnostic pitfalls.
