Kualitas pewarnaan Diff-Quick bergantung pada beberapa faktor diantaranya adalah metode fiksasi yaitu fiksasi kering dan fiksasi basah. Kedua metode tersebut memiliki kekurangannya masing-masing, fiksasi kering dapat menyebabkan pecahnya sel sedangkan fiksasi basah lebih memakan waktu dan biaya dalam pengerjaannya, namun fiksasi kering lebih sering digunakan karena lebih cepat dan murah. Tujuan penelitian untuk membandingkan hasil pewarnaan Diff-Quick sediaan sitologi yang difiksasi dengan metode fiksasi kering dan metode fiksasi basah. Jenis penelitian adalah penelitian eksperimen. Sampel diperoleh dari RS K.R.M.T. Wongsonegoro Semarang berjumlah 36 sediaan yang dibagi menjadi tiga kelompok yaitu kelompok kontrol, kelompok fiksasi kering, dan kelompok fiksasi basah. Ketiga kelompok tersebut diwarnai dengan Diff-Quick. Pewarnaan sediaan fiksasi kering memberikan hasil 4 sediaan kurang baik, 5 sediaan baik, dan 3 sediaan sangat baik sedangkan pewarnaan sediaan fiksasi basah memberikan hasil 0 sediaan kurang baik, 8 sediaan baik, dan 4 sediaan sangat baik. Hal ini menunjukkan hasil pewarnaan sediaan yang difiksasi basah memiliki kualitas yang cenderung lebih baik dan lebih konsisten dibanding hasil pewarnaan sediaan fiksasi kering. Meskipun secara statistik melalui uji Post-Hoc menunjukkan tidak ada perbedaan, kualitas pewarnaan Diff-Quick sediaan sitologi yang difiksasi dengan metode fiksasi basah lebih baik dari pada fiksasi kering.

ABSTRACT Cytodiagnostic fine needle aspiration biopsy specimens from toxic goitres were studied for signs of lymphoid infiltration. Comparison with histological sections of specimens obtained by surgery showed that an excess of lymphoid cells in the aspirate smears corresponded to a large number of lymphoid foci in these sections. Excess of lymphoid cells in the fine needle aspirates was also positively correlated with the occurrence of circulating thyroid antibodies against thyroglobulin and/or cytoplasmic antigen, but not with the presence of the long-acting thyroid stimulating factor, LATS. It also varied with age in that it was most common in the youngest patients and in patients between 40–55 years, while lymphoid infiltration was seldom seen in patients over 55 years. A finding of practical clinical interest was that in toxic goitres with cytological signs of lymphoid infiltration hyperthyroidism had less tendency to recur after treatment with thiocarbamide drugs than in those without such signs.

<b><i>Background:</i></b> Fine-needle aspiration biopsy (FNAB) in breast lesions offers accurate results in differentiating benign and malignant lesions. However, its role is unclear when core-needle biopsy (CNB) is available, the latter providing additional information regarding tumor grade, invasion, and hormone receptor status in malignant lesions. In benign breast lesions, especially in BIRADS category 4a and 4b, FNAB, and CNB provide similar pathological information, whereby FNAB may serve as a more rapid and cost-effective investigation. The study was planned to reevaluate the diagnostic accuracy of FNAB in BIRADS category 4a, 4b, and 4c lesions. <b><i>Materials and Methods:</i></b> FNAB and biopsy reports of all patients with breast lesions sent between September 1, 2018, and November 30, 2020, were collected and the International Academy of Cytology (IAC) Yokohama category and BIRADS score were recorded for each case. The rate of malignancy and the accuracy of FNAB in diagnosing malignancy were calculated for each BIRADS 4a, 4b, and 4c subgroup. <b><i>Results:</i></b> A total of 249 cases of BIRADS 4 lesions had corresponding cytology and histopathology diagnoses. FNAB showed high diagnostic accuracy in all BIRADS groups. A benign categorization was associated with a very low number of false-negative diagnoses, especially in BIRADS 4a lesions. <b><i>Conclusion:</i></b> The study reconfirms the excellent accuracy of breast FNAB using the IAC Yokohama system in diagnosing breast malignancies. Furthermore, BIRADS 4a lesions found to be belonging to the cytological benign category may be excluded from CRB and kept on clinical follow-up.
