1. Primary non-Hodgkin lymphoma of the cecum: a case reportMateja Kropivnik, Breda Jamar, Bojana Černelč, 2002, professional article Abstract: Background. Primary lymphoma of the colon is rare, constituting 0.4 % of primary colonic malignancies and usually involves cecum or rectum. The aim of this paper is to present the role and the importance of double contrast bariumenema (DCBE) in the diagnostic process. Case report. A 77 years old malewas admitted because of suspected inflammation in the area of total endoprosthesis of the left hip, inserted ten years before. Listeria monocytogenes was isolated from the aspirate and the patient treated with antibiotics. Twenty years ago the patient underwent nephrectomy because of hypernephroma of left kidney. At the time of admission he had sideropenic anaemia and he was febrile. Conclusion. The patient underwent many diagnostic procedures: ultrasound (US), computed tomography (CT), double contrast barium enema, which showed a tumour in the cecum, small bowel follow-through and scintigraphy. The diagnosis of primary non-Hodgkin lymphoma was established byhistology after biopsy at colonoscopy.

2. Ultrasound-guided aspiration biopsy of subclinical regional metastases of head and neck carcinomaAlenka Višnar-Perovič, Aleksandar Aničin, Živa Zupančič, Bojana Černelč, Alojz Šmid, Dubravka Vidmar, Milan Gorenc, 2000, original scientific article Abstract: Background. Studies concerned with the estimation of ultrasound (US) combined with ultrasound-guided aspiration biopsy (USGAB) in the detection of subclinical regional metastases from the planocellular carcinoma of head and neck are promising, but in few cases. Recently, the authors have pointed out the role of lymph node size parameters in order to decide about the use of USGAB. The aim of this study was to test the reliability of US-USGAB for the detection of subclinical regional metastases in patients with planocellular head and neck carcinomas, including the evaluation of lymph node size parameters. Patients and methods. 121 neck sides with no palpable metastases were examined by US in 77 patients with planocellular carcinomas of head and neck. Depending on the results obtained, USGAB was performed on 64 neck sides.After surgery, the results of US-USGAB were compared with histological findings of the dissected lymph nodes. Results. The study showed 77% overall sensitivity of US and USGAB, and 100% specificity, while the versal / longiyudinal diameter was the best predictor of metastatic lymph node involvement. Conclusion. The results of this study established that USGAB is an appropriate method for detection the subclinical regional metastases on neck, and should be included into routine diagnostic work up in the evaluationof the extent of head and necks carcinomas.

4. Ultrazvočno vodena aspiracijska biopsija s tanko iglo v diagnostiki ledvičnih tumorjevMargareta Strojan Fležar, Bojana Černelč, Helena Gutnik, Alenka Višnar-Perovič, 2011, professional article Abstract: Ultrazvočno vodena aspiracijska biopsija je v Sloveniji že dolga leta standardna metoda za morfološko diagnostiko radiološko težavnih ledvičnih tumorjev. V zadnjih letih se zanimanje za to diagnostično metodo povečuje tudi v Evropi, predvsem za dodatno diagnostiko majhnih tumorjev, ki merijo največ 3 cm. V naši analizi smo potrdili, da je metoda uporabna za diagnostiko majhnih tumorjev, če so vzorci dovolj celularni in reprezentativni za lezijo. V citopatološki diagnostiki so nam v pomoč tudi imunocitokemična barvanja, s katerimi lahko natančneje opredelimo tip ledvičnega karcinoma: svetlocelični, papilarni in kromofobni karcinom ledvičnih celic.
