Background and objectives:Objective in this retrospective study is to find out the incidence of different ovarian tumors of girls up to 20 years of age observed in last ten years in North Bengal Medical College and to correlate clinical and gross findings with histopathologic findings and to compare the incidence with other studies and follow-up of patients with malignant ovarian tumors.Materials and Methods:Findings were retrieved from records of different pathological reports and clinical reports.Results:Total 151 cases of ovarian tumors were received in pathology department in which 34 cases were malignant (22.6%). Amongst malignant cases, 66% are of germ-cell origin–dysgerminoma being the commonest. Strikingly we got 9 cases of malignant surface epithelial tumor. As per follow-up records most of the dysgerminoma came in stage IA and recovered fully following chemotherapy and radiotherapy. Amongst other malignant tumors, few lost the follow-up management and others expired due to metastasis.Conclusions:Patients from hilly areas of North Bengal and low socio-economic status led to lower detection rate of ovarian tumors in early stage which are absolutely necessary for proper guidelines of management to reduce mortality.

Background:Diagnosis of retroperitoneal lesions is one of the most difficult areas in surgical pathology. Both primary and metastatic tumors can grow silently in retroperitoneum before the appearance of clinical signs and symptoms. Guided aspiration cytology has shown a promising role in diagnosis of lesions in this region.Aims:This study was undertaken to evaluate the reliability of guided fine-needle aspiration cytology (FNAC) in the diagnosis of retroperitoneal masses and to study the spectrum of retroperitoneal lesions in a rural tertiary care hospital.Materials and Methods:This study was done on 71 patients presenting with retroperitoneal masses over a period of 20 months in a tertiary care hospital. Ultrasound-guided FNAC was done and the smears were stained by MGG and H and E stains. Histopathological corroboration could be done on all neoplastic lesions along with some non-neoplastic lesions.Results:Out of 71 cases, 48 cases (67.6%) were found to be neoplastic. Malignant tumors (35 cases) were more common than benign ones (13 cases). Malignant lesions were predominantly composed of lesions of lymph node (17 cases i.e. 48.57%) followed by sarcomas (5 cases) and germ cell tumors. Some uncommon retroperitoneal lesions like adrenal myelolipoma, renal angiomyolipoma, Burkitt's lymphoma and adrenocortical carcinoma were found in our study. Guided FNAC could diagnose all the malignant lesions with 100% accuracy except in 2 cases of poorly differentiated carcinoma which came out to be non-Hodgkin lymphoma on subsequent biopsies.Conclusion:Guided FNAC is an inexpensive, rapid and reliable method for diagnosis of retroperitoneal masses.

Pure lipoma of the uterus is a rare entity and only a few cases have been reported in the literature. Clinical symptoms and signs are similar to those found in leiomyoma and create preoperative diagnostic confusion. The histogenesis is still unclear. We report the case of a 70 year-old woman with pure lipoma of the uterus with calcification. (J Turkish-German Gynecol Assoc 2010; 11: 113-4) Key words: Lipoma, uterus Abstract ÖzetCase Report 113

Aim: Age, sex, living place (urban or rural), smoking, alcohol consumption, dietary pattern, obesity are considered as risk factors for Colorectal cancer. Our study was done to evaluate the association between these risk factors and colorectal cancer in the population of North Bengal. Materials and Methods:The present study was done over a period of one year as a hospital-based analytical observational type of study with cross-sectional type of study design. All the patients undergoing colorectal endoscopic biopsy at the Department of Surgery, NBMC&H during the study period for various clinical indications comprised the study population. History and clinical examination were done of the patients whose colorectal biopsy were taken and filled-up in a predesigned pre-tested proforma. Significance was tested at 95% confidence interval. Results:There is an increased risk of colorectal carcinoma (CRC) with increasing age in our study population. Odd's ratio for last 2 age groups are statistically significant with 2.83 for

Malignant tumors of the vagina in infants and children are rare, with primary germ cell tumor (endodermal sinus tumor [EST]) being rarer, which carries a dismal prognosis. This tumor is often clinically mistaken as botryoid rhabdomyosarcoma and, on histopathological examination, is often misdiagnosed as clear cell adenocarcinoma. Two cases of EST of the vagina in infants aged 9 and 17 months are reported. Both the patients presented with bleeding per vagina and clinically and by ultrasonography were diagnosed as sarcoma botryoides. Both were diagnosed as primary yolk sac tumors. The serum alfa fetoprotein (AFP) level was 4325 and 9328 ng/ml, respectively. One patient aged 9 months expired 2 months after receiving chemotherapy. The other, aged 17 months, was given chemotherapy followed by surgery with reduction of the AFP levels.
