Diagnostic accuracy of fine needle aspiration cytology of bone lesions: A study of Tertiary Care Institute.

AIMS AND OBJECTIVES: The aim is to study the spectrum and cytomorphological features of bone lesions and find out the diagnostic accuracy of Fine needle aspiration cytology (FNAC) on the same. MATERIALS AND METHODS: The study was a cross-sectional study conducted in the Department of Pathology and Orthopedics in a tertiary institute in north India over a period of 1 year in 55 patients. All the patients were subjected to FNAC of bone lesions followed by tru-cut or open bone biopsy. Cytosmears were stained with May Grunwald Giemsa and Hematoxylin and Eosin were done on biopsy specimens. Sensitivity and specificity were calculated in percentage with a 95% confidence interval with reference to biopsy specimens. RESULTS: Two peaks were observed; one between 11 and 40 years with 32 cases and another at 51 and 60 years with 12 cases. The male to female ratio was 1.4:1. In the present study, inflammatory lesions were present in 17 (31%) cases, 2 were tumor-like conditions; 10 (18%) cases of primary benign tumors, 26 (47.2%) cases were malignant. Out of these, 15 (27.2%) were primary malignant bone tumors and 11 (20%) were secondary in nature. The sensitivity, specificity, and diagnostic accuracy of the FNA of bone lesions were 55.17%, 79.04%, and 73.46%, respectively. CONCLUSION: Although there are a few limitations of FNAC such as low cellularity, small representative sample, and hemorrhagic aspirate, it can still be used as an initial diagnostic modality with proper clinical context for the management of bone lesions.

Synchronous Primary Endometrial and Fallopian Tube Carcinoma with Metchronous Renal Pelvis Carcinoma in One Patient: "Triple Cancer- A Rare Occurrence".

Triple primary cancers in one patient are a very rare finding and occur in only 0.5% of patients with cancers. Here, we report the case of triple malignancy in a 62-year-old woman who developed synchronous primary endometrial endometroid type and serous type of fallopian tube carcinoma, which is again a rare finding after 4 years of diagnosis of transitional cell carcinoma of the right renal pelvis.
