Abdominal palpation discovers tumor mass occasionally; therefore visualization is possible by using imaging technologies. Ultrasound (US) and computed tomography (CT) enables precise localization and tissue sampling by fine needle aspiration (FNA) for cytology analysis and additional diagnostic technologies. Material and methods: Data of 761 FNA of intraabdominal mass performed with CHIBA needle in last 10 years were analyzed. Tumor mass suitable for FNA were punctured in liver (335), pancreas (124), spleen (32) kidney (21), adrenal gland (7) and retroperitoneal and mesenterial lymph nodes (242). Smears were stained according to May-Grünwald-Giemsa and according to cytochemistry and immunocytochemistry methods. For differentiation of malignant lymphomas flow-cytometry immunofenotypisation, cytogenetic and/or molecular analysis (PCR) were additionally performed. Results: Out of total of 761 specimens malignant tumor was diagnosed in 532 (70%). Nonepithelial tumor was diagnosed in 154 (20%) - 21 sarcoma, 6 melanoma, 7 embriogenic tumors and 120 malignant lymphomas. Subtypes of sarcoma were determined based on cytomorphology and immunocytochemistry - 4 gastrointestinal stromal tumor (GIST), 3 liposarcoma, 2 rhabdomysarcoma, 2 leiomyosarcoma, 2 angiosarcoma, 1 fibrosarcoma and 7 samples were without subtype. Conclusion: US or CT guided FNA of abdominal tumor mass followed by cytoanalysis (cytochemistry and immunocytochemistry methods, flow-cytometry immunofenotypisation, cytogenetic and/or molecular analysis) is trustworthy diagnostic procedure for distinguishing non-epithelial from epithelial tumor and moreover for subtypisation of non-epithelial tumors. dinko.skegro@kb-merkur.hr
Clinical Cytology - Posters FINE NEEDLE ASPIRATION CYTOLOGY OF CHONDROID SYRINGOMA Škoro M1 , Trutin Ostović K1 , Čikara I2 , Müller D3 , Novak NP1 , Virag M4 1Dubrava University Hospital, Department of Clinical Cytology and Cytometry, Zagreb, Croatia 2Dubrava University Hospital, Department of Diagnostic and Interventional Radiology, Zagreb, Croatia 3 Dubrava University Hospital, Department of Patology, Zagreb, Croatia 4 Dubrava University Hospital, Department of Maxillofacial Surgery, Zagreb, Croatia Aim: The aim of this case report is to show importance of FNA cytology in preoperative investigation and differential diagnosis of rare skin lesions. Methods: FNA cytology is a safe diagnostic procedure that may be used for diagnostic purposes. We present a 63 year-old man with painless, subcutaneous nodule on the neck of five years duration. Ultrasonography showed a small subcutaneous, inhomogeneous mass with hypervascularisation. Radiologist required an ultrasound-guided FNA biopsy. During that procedure the lesion started to abundantly bleed. Results: The smears were cellular with numerous clusters of small, monomorphic epithelial cells embedded in a PAS positive myxoid stroma. The nuclei were round to oval with fine, evenly distributed chromatin and cytoplasm was dense, moderate in amount , with well-defined cell borders. The combination of epithelial elements and myxoid stroma suggested a diagnosis of chondroid syringoma. Conclusion: Chondroid syringoma is rare, benign appendageal tumor. Because of its unremarkable clinical presentation it is often overlooked. FNA cytology plays important role in the preoperative investigation of skin tumors such as chondroid syringoma. It may be useful to determine pathology before histological examination. marija.skoro@kbd.hr 139 4 th Croatian Congress of Clinical Cytology / 1 st Croatian Symposium of Analytical Cytology / 2 nd Croatian Symposium of Cytotechnology
