Background:Fine needle aspiration cytology (FNAC) has a high rating in the assessment of breast lesions. Various methods have been used to diagnose cytology of breast lesions.Aims:Present study was undertaken to evaluate the feasibility of application of systematic pattern analysis based on morphology in diagnosing breast aspirates.Materials and Methods:This is a retrospective study of FNAC of the breast done over a period of 4 years in a tertiary care centre. A total of 225 cases of breast lesions for which FNAC was done with histological follow-up were included in the study. Breast aspirates were provisionally diagnosed based on systematic pattern analysis. Aspirates were grouped into six categories based on predominant cellular pattern, and correlation between cytological and histological diagnosis was assessed.Results:Application of pattern analysis on FNAC of breast lesions in our study had a sensitivity of 94.5%, specificity of 98%, diagnostic accuracy of 97%, positive predictive value of 95.8%, and negative predictive value of 97.4%.Conclusions:Systematic pattern analysis based on morphology of FNAC smears was found to be highly reliable and could be easily reproducible in the assessment of breast masses.

Fine needle aspiration cytology (FNAC) of the thyroid is a simple, accurate, fast, economical and safe method for the diagnosis of thyroid lesions on FNA. The objective of this study was application of pattern analysis in the interpretation of thyroid lesions. Two hundred and thirty three cases of thyroid lesion were reviewed, which had histopathological correlation. Smears were classified based on primary (predominant) and secondary (next dominant) pattern and categorized. The variation between combined and final cytological diagnosis was correlated with the histopathological diagnosis. The sensitivity, specificity and diagnostic accuracy for the diagnosis of malignancy were 90.47, 100 and 99.14%. Our study demonstrates the feasibility and applicability of pattern analysis in diagnosing thyroid lesions, which could be easily reproducible.

Giant Cell Tumours Of Tendon Sheath (GCTTS) are the second most frequent soft tissue tumours affecting the hand with an overall incidence of 1 in 50,000 individuals. These tumours are usually localized and solitary, with multiple GCTTS occurring rarely. Multi-centric origin is considered unusual and very few cases of multiple GCTTS have been reported till date. Here, we report a rare case of a 26-year-old female who presented with multiple painless swellings on palmar aspect of little finger of right hand since six months. Clinical diagnosis of Dupuytren's contracture was given. Intraoperative examination revealed multiple separate nodules, firmly attached to the flexor tendon synovial sheath. Histopathology showed features of GCTTS.
