ABSTRACT
Gastrointestinal tract is the most common site for the development ofextra nodal lymphoma. This study was done to analyze clinical and pathological features as well as the treatment outcome of this disease. We carried out analysis of25 cases of primary gastrointestinal (GI) lymphomas during period from March 2001 to February 2003 at Gujarat Cancer & Research Institute. Out of 25 cases of primary GI lymphoma, nine cases of gastric lymphoma, nine cases of small intestinal lymphoma and seven cases of large intestinal lymphoma were identified. A male to female ratio of 2.6:1 was observed. Peak incidence was observed infirst and second decades of life (range 4-63 years). Abdominal pain and abdominal lump were the two most common presenting symptoms. Diffuse large B-cell type and Burkitt's lymphoma were the most common histologic variants, accounting for equal proportions (36% each). All the patients were treated with either surgery alone or in combination of surgery, chemotherapy and radiotherapy depending on the site, stage and histology. Anti H-pylori kit was used in early stage GI maltomas. 18 cases of GI lymphoma were evaluable, and out of these, 66.6% (11 cases) attained complete remission with a median follow up time of 12 months. The disease free survival was 50% (9 cases), and the overall survival was 72.2% (13 cases). In conclusion, although there are considerable therapeutic controversies, surgery with adjuvant chemotherapy and radiotherapy yield good survival. Clinical and histopathologic characteristics and prognosis of our cases with primary gastrointestinal lymphoma were usually similar to the cases in western countries with some differences in the incidence and histologic subtypes.

Teratoid Wilms' tumor with raised serum alpha-fetoprotein level is an unusual type of tumor. We, here, describe a twelve month old boy presenting with lumbar mass. Clinical features, radiological findings, gross examination, and histomorphological features are studied, and various differential diagnoses like Wilms' tumor with heterologous elements, intrarenal teratoma and metastatic germ cell tumor are taken into consideration.

The aim of this study was to assess the usefulness of fine needle aspiration cytology (FNAC) as a diagnostic method in lung tumour as well as to determine the incidence of lung cancer in various age and sex group and in relation with smoking. Hundred cases of lung tumours were investigated. Out of 100 patients, 88 were male and 12 were female. The age of patients varies from 23-78 years most of the patient were in the age group of 50-70 years. The most common tumour was squamous cell carcinoma (45%) followed by adenocarcinoma (22%), small cell carcinoma (16%) and large cell carcinoma (8%). Eighty out of 100 patient had history of smoking. Diagnostic accuracy of cytology with final histopathological report was established with accuracy rate of 95%.

The aim of this study was to assess the usefulness and accuracy of cytologic smears by making crush preparation as a diagnostic method, in central nervous system tumors. 278 patients with central nervous system tumors were investigated. In 98 cases, material was obtained intraoperatively during craniotomy and in 180 cases stereotactic biopsies were done. In all the cases crush preparations were made, and cytologic diagnosis was correlated with final histologic diagnosis. 244 out of 278 patients showed correlation with histopathological diagnosis. So, in present study diagnostic accuracy was 87.76%. In 18 cases no definite diagnosis was made due to inadequate material. Majority of the patients were in age group 31 to 40 years (72 cases). The youngest patient was three years old and the eldest was 87 years old. The most common tumor in intracranial cavity was astrocytoma (56.68%), followed by meningioma (6.88%), medulloblastoma (5.66%) and ependymoma (5.56%). The most common tumor in intraspinal cavity was ependymoma (38.46%), followed by meningioma (23.07%) and schwannoma (23.07%). In conclusion, crush preparation is an effective, simple, rapid, relatively safe and reliable technique for the diagnosis of central nervous system tumors. Diagnostic accuracy of cytology with final histopathological report is established with accuracy rate of 87.76%.

A case of primary chondrosarcoma of the left lung in 50 year-old man is presented. The tumor was diagnosed as primary chondrosarcoma of the lung after exclusion of any primary lesion elsewhere. Histologically, tumor consisted of predominantly chondromatous lesion. Immunohistochemistry showed that tumor cells positive for S-100 protein and vimentin, and negative for epithelial markers. On the basis of clinical, histological and immunohistochemical studies, the tumor was diagnosed as a primary chondrosarcoma of the lung.

The authors describe a case of primary mucinous carcinoma of urachus in 65 years old male. Patient presented with hematuria with suprapubic mass. The patient underwent total cystectomy with en bloc excision of the tumor mass and umbilicus. Histological examination showed features of mucinous carcinoma of urachus. A clinicopathological study and brief review of literature is presented.

Cytological grading of breast cancer is not well established despite histological grading having gained a strong foothold. In our study we have analyzed 50 cases of breast carcinoma which included invasive ductal carcinoma, invasive lobular carcinoma, mucinous carcinoma, stromal sarcoma, apocrine carcinoma, papillary carcinoma. Papanicolaou smears were graded according to established Hunt's, Simplified Black and Modified Black grading systems. They were then compared with the Scarff Bloom Richardson grading system. Simplified Black grading system has been recommended for cytological grading of breast neoplasia because of its lucidity and its reproducibility. Cytological grading of breast neoplasia is important for neo adjuvant chemotherapy and also for predicting the prognosis of the patient on FNAC alone. Incorporation of other parameters like apoptosis and bcl-2 is also recommended.

Adult granulosa cell tumor (GCT) of the ovary is the most common malignancy amongst the sex cord stromal tumors. Clinical stage, age, tumor size, residual disease and several histologic factors have been reported to be of prognostic significance. There were 839 ovarian malignancies at our institute during the period from 1998 to 2002. Out of 54 granulosa cell tumors, 40 cases were evaluable which includes 37 cases of adult GCT and 3 cases of juvenile GCT. They were studied retrospectively. Majority of patients presented with abdominal symptoms and FIGO stage I. All patients were treated surgically and 62.1% of adult GCTs were given post-operative chemotherapy. Clinical stage, presence of residual disease and tumor volume were the most important prognostic factors. Age of patient, menstrual status, post-operative chemotherapy, mitosis or histological patterns were of little significance in our study.
