Mesenteric masses are infrequent lesions ranging from benign cyst to aggressive malignancies and often present as diagnostic and therapeutic challenge. The mesentery is a frequent recipient of metastasis from the gastrointestinal tract, pancreas, and biliary cancers. Primary mesenteric tumours are relatively rare, mostly mesenchymal in origin and benign in nature. Examples include gastrointestinal stromal tumours and smooth muscle tumours. Pleomorphic leiomyosarcoma of mesocolon is extremely rare with a reported incidence of 1:350,000. So accurate preoperative diagnosis of mesenteric soft tissue tumours is generally difficult. It accounts for less than 1% of the malignant tumours found in colon. Leiomyosarcoma is a malignant tumour arising from smooth cell lineage. These tumours occur most commonly in middle aged individuals. We describe a case of pleomorphic leiomyosarcoma arising from the colonic mesentery in a 27-year-old male patient, with massive lower gastrointestinal bleed (LGI bleed) causing drop in haemoglobin level from 9 mg/dl to 6 mg/dl. Ultrasonography and CECT abdomen suggestive of (17.5×11.6×10.6) cm mass in left side upper abdomen in splenic hilar region. Left hemicolectomy with excision of mass with splenectomy and distal pancreatectomy done. The diagnosis was based on histopathological evaluation using immunohistochemistry (IHC). Histopathological report suggestive of pleomorphic leiomyosarcoma with SMA and vimentin positivity on immunohistochemistry but CD 34 and CD 117 were negative, differentiating it from GIST.

Epidemiological Characteristics

Introduction. Lung cancer represents the most common malignant tumour among men, and appears more and more frequently among women in many countries worldwide. The aims of this descriptive epidemiological study were to evaluate the mortality trends of all malignant tumours and lung cancer in Central Serbia from 1990 to 1999, and to estimate the incidence, mortality and the basic demographic characteristics of lung cancer in Central Serbia in 1999. Material and methods. The source of data concerning cancer cases in 1999 was the Cancer Registry of Central Serbia, while data of the Republic Statistics Institute were used for the analysis of mortality trends for the period 1990-1999. All rates were standardized by the direct method, to the world standard population. Confidence intervals for mortality rates were assessed with 95% level of probability. Linear regression coefficient was determined by Fisher's test. Results. The mortality rates showed rising tendencies for both lung cancer (y=-1876.26+0.96x, p=0.028 for men; y=654.78U).33x, p-0.001 for women) and all malignant tumours (y=-4139.88+2.15x, p=0.163 for men; y=3649.68 + 1.88x, p=0.016 for women), with statistically significant increase being observed for all trends, except all malignant tumours among men. In the year 1999, lung cancer ranked first among men and third among women, with 29.2% and 10.3% of cancer mortality respectively. The age-specific mortality rates were much higher in men in all age groups. Mortality increased with age and the highest rates were found in the age group 70-74 for both sexes. The highest incidence and mortality rates were reported in Belgrade, Moravicki and Sumadijski district. .

Abstract Objectives. Early detection of malignant tumour is a prerequisite for a successful treatment. Here we investigate if thymidine kinase 1 is more sensitive than imaging technology to discover small invisible malignant tumours.Material and Methods. The cellular concentration of TK1 was determined by a novel automatic chemiluminescence analyzer of magnetic particle immune sandwich minimum. The primary and secondary antibodies linked to the magnetic beads were chicken anti-human thymidine kinase 1 IgY-polyclonal antibodies (IgY pAb). The minimum number of cells able to be detected by the novel detection technology using an automatic chemiluminescence analyzer were determined based on the cellar TK1 concentration of low and high TK1 cell lines of known cell count.Results. The TK1 concentration of malignant cell was found to be 0.021 pg/cell. Assuming 200 pg of total protein/cell, TK1 corresponds to 0.01 % of the total protein/cell. The concentration of TK1 in human blood serum of malignant patients is in the range of 2-10 pmol/l (pM), corresponding to about 50 x106 growing cells in the body that release TK1 into 5 litre blood. The limit visibility by imaging of a tumour is about 1 mm in diameter, corresponding to about 109cells of a cell diameter of 1µm. Conclusion. TK1 is more sensitive than imaging.

Background:Tumours and tumour like lesions of the colon and rectum have overlapping clinical presentation and may be difcult to diagnose on clinical grounds alone. Histopathological examination although helpful to arrive at correct diagnosis, at times may be difcult and may require ancillary tests such as immunohistochemistry. Materials and Methods: A prospective cross sectional study enrolled 125 cases of colorectal biopsies after histopathological conrmation of tumours and tumour like lesions. The specimens were received at the Department of Pathology, DMCH, Laheriasarai, Bihar from December 2019 to November 2020. Results: Out of 125 cases, 32 cases were benign tumours, 36 cases were malignant tumours and 57 cases were tumour like lesions. Most common age range was 51-60 years with mean age of 38 years. Males comprised 76.74% and females 23.26% with ratio of 3:1. Juvenile polyp was the commonest lesion. Among benign tumours, tubular adenoma was the most common (19.2%), adenocarcinoma was most common malignant tumour (25.6%) and juvenile polyp was the most common tumour like lesion (27.2%). Left side was most common side (66.67%) and rectum was the most common site (48.8%). Conclusions: The commonest indications for colorectal biopsies were tumours and tumour like lesions. Juvenile polyp was the most common tumour like lesion, tubular adenoma was the most common benign tumour and adenocarcinoma was the most common malignant tumour. Histopathological examination is a gold standard for conrmation of all tumour and tumours like lesions of colon and rectum.

ABSTRACT Typhoid fever is caused by gram-negative organism Salmonella typhi. The usual presentation is high-grade fever, but complications like gastrointestinal (GI) hemorrhage and perforation are also seen frequently. With the advent of antibiotics, these complications are rarely seen now. We present a case of a young female who was admitted with a diagnosis of typhoid fever presented with a massive GI bleed from ulcers in the terminal ileum and was managed conservatively without endotherapy and surgery.

Introduction and Aim: Various non-neoplastic and neoplastic lesions occur in the kidney. Pathological assessment of gross and microscopic features in nephrectomy specimens is essential for diagnosis and predicts the prognosis in malignant tumours. Materials and Methods: Case records of 46 nephrectomy specimens received between two-year periods were retrieved. Detailed gross and histopathological and immunohistochemical features were studied, and malignant tumours were analysed using CAP protocol. Results: Out of 46 nephrectomy specimens, 17 were non-neoplastic and 29 neoplastic. Males constituted 32 cases and females 14 cases. The commonest non-neoplastic kidney lesion was chronic pyelonephritis with hydronephrosis (29%). The mixed epithelial and stromal tumour was the frequently encountered benign tumour (50%). Renal cell carcinoma was the most common malignant tumour in adults (70%) and Wilms tumour in children (4%). Conclusion: Histopathological examination of nephrectomy specimens helps in diagnosing, staging, and planning the management.

Soft tissue tumours of the elbow are mostly benign. Malignant tumours in this area, although uncommon, often present unique clinical and histopathological characteristics that are helpful for diagnosis. Management of soft tissue tumours around the elbow may be challenging because of their rarity and the proximity to neurovascular structures. Careful staging, histological diagnosis and treatment are essential to optimize clinical outcome. A missed or delayed diagnosis or an improperly executed biopsy may have devastating consequences for the patient. This article reviews the most common benign and malignant soft tissue tumours of the elbow and discusses the clinicopathological findings, imaging features and current therapeutic concepts.

The prognostic value of long intergenic non-protein coding RNA 460 (LINC00460) overexpression in human solid malignant tumours remains unclear. Therefore, we conducted the meta-analysis to systematically review and assess the evidence for the correlation between LINC00460 overexpression and clinicopathological features and overall survival (OS) of patients with solid malignant tumour. An electronic search of PubMed, EMBASE, Web of Science, CNKI, Cochrane Library, Chinese Biological Medical Literature database and WanFang database was applied to select eligible articles. Pooled ORs or HRs with their 95% CIs were calculated to estimate the effects. 9 eligible studies with a total of 935 patients were enrolled in this meta-analysis. The results revealed that high LINC00460 expression was associated with positive lymph node metastasis (positive vs negative: OR=2.97, 95% CI 1.74 to 5.05, p=0.812), advanced tumour-node-metastasis stage (III+IV vs I+II: OR=2.82, 95% CI 1.64 to 4.85, p=0.193) and poorer differentiation (high vs low: OR=0.60, 95% CI 0.36 to 0.99, p=0.569). Additionally, the overexpression of LINC00460 could predict a poorer OS (HR=1.57, 95% CI 1.39 to 1.77) and the shorter disease-free survival (HR=2.32, 95% CI 1.25 to 4.31). Furthermore, according to subgroup analysis and meta-regression results, the heterogeneity of current meta-analysis may be attributed to the differences of cancer type and follow-up months. High expression of LINC00460 could predict poor prognosis in patients with solid malignant tumour. LINC00460 may serve as potential prognostic biomarker for clinical outcomes in various human solid malignant tumours.

Background: The current WHO classification has categorized soft tissue tumours into benign, malignant and so-called intermediate neoplasms. Soft tissue sarcoma comprises <1% of adult cancers. The aim of the study was to clinically correlate soft tissue neoplasms and study the histomorphological features of various malignant soft tissue tumors.Methods: This was a retrospective study conducted in a tertiary care hospital in Mangalore, India from January 2019 to June 2020. Clinical details of all cases of soft tissue neoplasms retrieved from the medical records of our institution. Data collected included age, gender, presenting symptoms, site and size of soft tissue neoplasms and clinical diagnosis. Pathological diagnosis of these tumours was made and details recorded.Results: A total of 113 cases of soft tissue neoplasms were collected. 94.4% benign and 18.6 %. malignant tumours were present. 77% cases presented with swelling whereas 23% presented with pain. Majority of benign soft tissue tumours were located in the trunk (36.9%) and the most common type was lipomas (66.38%). Malignant soft tissue tumours showed male to female ratio of 1.33:1. Most predilection was noted for the extremities (42.8%) and leiomyosarcomas were the most common type (38%).Conclusions: The incidence of malignant soft tissue tumours is rare. Majority of the cases were noted in the extremities. Leiomyosarcoma was the most common type, in our study. Lipomas were the most common benign soft tissue tumours, and majority of the benign tumours were located in the trunk.

Mucosa-associated lymphoid tissue (MALT) lymphoma of the parotid gland is a rare entity among head and neck tumours. We report a case of a patient with a medical history of diffuse large B-cell Non-Hodgkin Lymphoma with complete remission following chemotherapy, who presented seven years afterwards with a progressive painless hard swelling of the right parotidgland. Ultrasonography followed by contrast-enhanced MRI features was consistent with a malignant tumour. Consequently, fine and core needle aspiration biopsy were performed under ultrasound guidance and the final histopathological result was MALT lymphoma of the parotid gland. The most important particularity of the case is the sequential development of two different histopathological types of Non-Hodgkin Lymphoma, both of B-cell lineage.
