pylori infection. Also, after combining the recombinant vector with nanoparticles we observed a better immune response was observed. In future studies this recombinant construct can be used as a biomarker and therapeutic approaches in eukaryotic systems.

Breast is a rare primary localization with few cases described in the literature. We present an updated and systematic review and discuss the possible mechanisms of spreading, diagnostic and treatment options. MATERIALS AND METHODS We performed a literature search in PUBMED using the key words ‘hydatid disease’, ‘cystic echinococcosis’ and ‘breast echinococcosis’ without time limitation. Only studies reporting breast cystic echinococcosis were included. RESULTS Overall, 121 cases with cystic echinococcosis and 2 with alveolar echinococcosis were reported. A total of 52 cases were included in the analysis. The mean size of cysts was 5.5 cm (range 1.7-12). The most common clinical presentation was painless lump presented from 4 months to 19 years before the final diagnosis. Most cases had isolated breast CE, few cases had synchronous localizations – femoral, thigh and lung, and previous liver CE. Most were active CL and CE1-2 cysts (72%). Ultrasound was used in 83%, followed by mammography (35%). Fine needle aspiration was reported in 27 cases with positive finding in 59%. CONCLUSIONS In cases with cystic breast lesions from endemic regions we recommend the US as a gold standard. CT and MRT are more accurate but expensive tools without the potential to change the surgical tactic. In contrast to the other localizations of CE, complete excision of the cysts is the best diagnostic and treatment approach.

JM-8 A dermal, solid, grayish-yellow, desmin-negative trichrome-bluish tumor measured 1.5 cm in diameter pT1a (edition 8 pTNM). It was composed of spindle cells. It was consistent with dermatofibrosarcoma protuberans (ICD-O3 8832/3) in areas of low mitotic activity, low atypia and sustained CD34 positivity. CD34-negative texture with high mitotic index and atypia was consistent with the high grade sarcoma apparently of fibrous origin, given category of poorly differentiated fibrosarcoma. The high grade component was graded (G3) and scored according to French Federation of Cancer Centers Sarcoma Group (FNCLCC) total score of 6 points tumor differentiation 3 points + Mitotic count 3 points (up to 26 mitoses/ 10HPF in high-grade fields), + no necrosis 0 points. In low grade sarcomatous component ADAMTS20 (NM_025003 c.1661C>T, p.P554L) NF1 (NM_001042492 c. 2173G>T, p.E725X) and PKHD1 (NM_138694 c. 11074C>T, p.R3692X) were revealed with following allelic frequencies 25%, 27% and 17%. In high grade component allelic frequencies of the same mentioned mutations were 30%, 30% and 14% respectively. In the light of our findings, none of detected mutations can be regarded as a mutation that would definitely induce phenotype of high malignancy, because ADAMTS20, NF1 and PKHD1 mutations were detected both in high grade sarcoma and in low grade areas of dermatofibrosarcoma protuberans. It also points that these mutations appeared on early stages of tumor development.INTRODUCTION Testicular cancers detected in older males are mostly testicular lymphomas. Primary testicular lymphoma (PTL) is a rare, clinically aggressive form of extranodal lymphoma. In population-based studies, the incidence of PTL is 0.09-0.26/100.000. The vast majority of PTL are diffuse large B-cell lymphoma (DLBCL). CASE PRESENTATION We present a case of PTL diagnosed in a 68-year-old male patient and also, we discuss the incidence, clinical presentation, prognostic factors and management of this rare pathology in the light of current literature. Histopathological and immunohistochemical exams of the patient confirmed the diagnosis of DLBCL after radical orchiectomy. According to the internal prognostic index (IPI), patients’ IPI score was evaluated as 5 and according to Ann Arbor staging, patients’ stage was interpreted as grade 3E. Cyclophosphamide, vincristine, etoposide, and prednisolone chemotherapy was planned for the patient and until now, the patient received his first chemotherapy regimen. DISCUSSION Primary testicular lymphoma should be kept in mind for every patient who admits with a testicular mass, especially in advanced age. Misinterpreatation of the clinical findings can delay the definitive diagnosis. Primary testicular lymphoma should be managed with a multi-disciplinary team including urologists, medical and radiation oncologists.

One of the most frequently used qualitative occlusal indicators is the articulating paper. Its reliability is often disputed because this indicator could produce false positive results or fail to register any occlusal contacts. AIM To compare the number and size of the recorded contacts on a tooth surface obtained with articulating paper and foil. MATERIALS AND METHODS Typodonts of upper and lower jaw with intact dental arches Frasaco A-3Z were fixed in a Girbach arcon articulator. Articulating contacts were marked with 12-micron Bausch articulating foil and 200-micron Bausch articulating paper under the same load. For each study a new sheet of the occlusal indicators was used, and 10 repetitions were made for each one. After every marking, the lower jaw was dismounted from the articulator and the distribution of the markings was videographed using a camera. The number of occlusal contacts was entered in a table.
