Paranasal fibrosarcoma of nasal cavity and paranasal sinuses is a very rare malignant tumor. It is usually presented with nasal obstruction and epistaxis. In this clinical report, clinical symptoms, pathogenesis, and treatment principles of a paranasal fibrosarcoma originating from the right maxillary sinus and obstructing the right nasal passage are discussed.A 55-year-old male patient was admitted to the authors clinic with complaints of nasal obstruction and epistaxis lasting for 2 years. Anterior rhinoscopy revealed a mass lesion which obstructed the right nasal passage and caused frequent epistaxis. An opacity consistent with soft tissue lesion which was originated from the right maxillary sinus and filled the right nasal passage was observed in paranasal tomography. Magnetic resonance imaging revealed that the mass lesion was contrasted. Tumor was seen to erode orbital floor, and lateral and anterior walls of the maxillary sinus. Biopsy result was reported as papilloma. The patient was treated with Denker approach as anterior wall of the maxillary sinus was eroded by the tumor lesion and the mass lesion was excised. The patient received postoperative radiotherapy as pathological diagnosis was reported as paranasal fibrosarcoma.

Objective: This study aimed to compare cytomorphology of ThinPrep Papanicolaou (TP PAP) method with the macroscopic-microscopic findings of the nodules on fresh thyroidectomy specimens.Study Design: A total of 75 thyroid surgical specimens were included in our study. Fine Needle Aspiration Biopsy (FNAB) of specimens was performed by a pathologist. Aspirate was taken into TP liquid and stained with PAP. We defined cytological findings, compatible with macroscopic-microscopic findings. Results:In cytologic evaluation 108 nodules were diagnosed benign, while 18 nodules were malignant and 2 cystic nodules were insufficient. Cytological diagnosis was compatible with histologically benign a total of 110 nodules, and 18 malignant nodules. Nuclear groove/irregular nuclear membrane, nuclear overlap/crowding, nuclear enlargement, nuclear pseudoinclusion, pale/fine chromatin are determined as statistically significant cytological parameters in malignant cases. Conclusion:FNAB and the histo-morphological and TP PAP cytological slides were evaluated by pathologists at every stage of biopsy process. It is clearly understood how important it is to obtain adequate cells from the benign or malignant thyroid nodules with this method. Although controversial opinions among the cytopathologists regarding the association using TP method are present, in this study we revealed that TP method is easy to use for FNAB.

Phone: +90 364 223 03 00 ÖZ Amaç: Çorum ilinde bölgesel tümör istatistiklerinin oluşturulmasına katkıda bulunacak güvenilir bilgiler sağlamak amacıyla bu ilde tanı konulan kanser olgularının yaş, cinsiyet ve organ dağılım frekanslarını belirlemeyi amaçladık. Gereç ve Yöntem:Bu tanımlayıcı retrospektif çalışmada Çorum ilinde hizmet veren bir üniversite hastanesi ve iki özel hastanenin patoloji bölümlerinin arşiv kayıtları incelendi. Toplam 138.973 kayıtlı patoloji raporu tarandı. Primer odakları bilinen metastatik kanserler çalışma dışı tutuldu. Kanser tanısı alan toplam 2184 olgunun en sık görülen 10 kanser tipine göre cinsiyet, yaş ve sistem/organ dağılımları belirlendi.Bulgular: Erkek/kadın oranı 1.44 olup ortalama yaş 64.26 yıldı. Kanser erkeklerde en sık 70-79 yaş aralığında (%35,27) görülmekteyken ikinci en sık aralık 60-69 yaş aralığıydı (%23,88). Kanser kadınlarda en sık 70-79 yaş aralığında (%24,16) görülmekteyken, ikinci en sık aralık 60-69 yaş aralığıydı (%22,60). En sık görülen ilk beş kanser sırasıyla cilt (%33,60), prostat (%13,87), mide (%9,07), mesane (%8,61) ve meme kanseriydi (%7,88).Sonuç: Çorum ilinde tanı konulan kanser olgularının organ/sistem dağılımı Türkiye genelindeki verilerden farklıdır. Güvenilir verilerin elde edilebilmesi için kanser kayıt merkezlerinin gelişimi, aktif kanser kayıt sistemine geçilmesi ve tüm sağlık kuruluşlarından elde edilecek kanser verilerinin tek bir organizasyon altında birleştirilmesi gereklidir.Anahtar Sözcükler: Epidemiyoloji, Kanser, Türkiye ABSTRACTObjective: In order to help obtain accurate knowledge and to contribute to the establishment of data for regional tumor statistics, we aimed to determine the frequency distribution of cancer cases that was diagnosed in Çorum province. Material and Method:In this descriptive study, we retrospectively reviewed the archive records of the pathology departments' of one university hospital and two private hospitals serving in the province of Çorum. A total of 138,973 recorded pathology reports were reviewed. Metastatic cancers with a known primary source were excluded. A total of 2184 cases with a diagnosis of cancer were recorded by gender, age, and system/organ and classified to 10 most frequent types of cancer both in general and in terms of gender distribution. Results:The male to female ratio was 1.44 and the mean age was 64.26 years. The cancer is most commonly encountered between 70 and 79 years of age (35.27%) in males whereas the second most common interval was 60 to 69 years of age (23.88%). In females, the cancer is most commonly encountered between 70 and 79 years of age (24.16%) whereas the second most common interval was 60 to 69 years of age (22.60%). The top five cancers were skin (33.60%), prostate (13.87%), stomach (9.07%), urinary bladder (8.61%) and breast (7.88%). Conclusion:Distribution of organ/system involvement of cancer cases that were diagnosed in Çorum is quite different from the data regarding Turkey in general. Development of cancer registry centers, upgrading to an active registry system...
