Liposarcoma, a malignant tumor originating from fat cells, is rare occurrence in the retroperitoneal region. Surgical resection standard method for treating this cancer. This type of classified into common subtypes, which include well-differentiated liposarcoma and dedifferentiated liposarcoma. A 53-year-old male patient presented with lower left quadrant (LLQ) pain melena two weeks. Further diagnostic evaluation, including colonoscopy, revealed 50 mm polyp hepatic flexure or distal...
Acquired reactive perforating collagenosis (ARPC) is an uncommon dermatosis characterized by transepidermal elimination of altered collagen. It commonly seen in patients with diabetes mellitus and/or chronic renal insufficiency. Rarely, it has been reported association malignancy and other conditions. We report a 30-year-old woman insulin-dependent who presented multiple, discrete, violaceous, hyperkeratotic papules on the extensor aspects both legs, characteristic ARPC. Four months later,...

Abdominal injury often divided into two categories: blunt penetrating injuries. This study aims to determine epidemiological clinical characteristics these types abdominal injuries in patients registered with National Trauma Registry Iran (NTRI).

COVID-19 virus is thought to complicate underlying conditions, including acalculous cholecystitis. Two patients with gangrenous gallbladder are reported who were not involved severe pneumonia.We present two non-critically ill presenting Both had and undergo cholecystectomy. Upon surgery, one of the showed patchy gangrene on other, a fully gallbladder.There may be possibility for cholecystitis develop ischemic gallbladder.
Several biomarkers have been investigated to predict the biological behavior and prognosis of patients with bladder cancer. We evaluated role two important markers including BCL2 CK20 in evaluating tumors.This cross-sectional study was performed on 30 suffering from one neoplasms bladder. To evaluate expression markers, neoplastic tissue sample initially extracted immunohistochemistry staining employed.The positivity patients' specimens found be 53.3% 10.0%, respectively. There no...
ABSTRACT Introduction: There are some evidences for the relationship between expression of epidermal growth factor receptor (EGFR) gene and clinical histopathological behavior high grade glioma. However, such a can take quite different forms in societies. We aimed to evaluate EGFR status glioma its with patterns tumor. Methods: studied immunohistochemichal 30 brain surgical resection specimens grades. All samples were from pathology department Sina Hospital Tehran-Iran 2020 2021. Results:...
Although percutaneous nephrolithotomy (PCNL) is a gold standard treatment of large kidney stones, vascular injuries like pseudoaneurysm (PA) and arteriovenous fistula (AVF) may occur due to renal punctures. These endovascular complications need urgent intervention be diagnosed managed early. In this case series, 14 patients who had hematuria after PCNL were by using angiography identify the pathology. Among them, we identified 10 with PA 4 AVF, 1 patient both subscapular hematoma PA....
Traumatic diaphragmatic injury is known to present with the spectrum of symptoms, and most patients would have some symptoms due abdominal organ herniation. Majority injuries tend on left hemidiaphragm but right-sided also occur mostly subtle, delayed presentation buffering effect liver.A 65-year-old male presented emergency department a complaint nausea vomiting reported no bowel movement or passing flatus for 5 days. Upon further questioning, he recalled that fell from tractor while...
Introduction: Changes in body composition after different bariatric surgeries have been studied extensively, but most of them emphasized on Roux-en-Y gastric bypass. Only a few studies assessed the effects sleeve gastrectomy (SG). Also, effect one anastomosis bypass (OAGB) is not fully apprehended. Furthermore, there no agreement how much fat-free mass (FFM) loss tolerable weight interventions. Therefore, we decided to assess reduction fat (FM) and FFM at 1, 3, 6, 12 months two types surgery...
Abstract Background Almost all cases of renal hydatid cysts need surgical intervention for treatment. We report a case isolated cyst treated successfully only with medical therapy. Case presentation This is 79-year-old veterinarian presented right flank pain, hydatiduria and positive echinococcus granulosus serology. A 70*50 mm daughter in mid-portion kidney on was changed into 60*40 without at last follow-up. Due to patient’s refusal surgery, our patient received treatment including...
and importance: COVID-19 has been associated with thrombotic events in a variety of organs systems, pulmonary embolism being the most prevalent. Splenic infarction, renal intestinal ischemia have all documented recently as abdominal visceral infarctions.A 59 years old female patient history disease was admitted to our hospital due her left upper quadrant flank pain. She had heel color change few days. We perform an ultrasound it shown vein thrombosis. So, heparin infusion started for her....
Splenic artery aneurysms (SAAs) account for more than half of all visceral aneurysms. Small SAAs are usually asymptomatic, but giant likely to cause symptoms and result in life-threatening complications; these treatment can be challenging. includes laparotomy, laparoscopy, or endovascular techniques.
Abstract Background Special attention has been recently paid to the expression of SOX10 marker, which is actually responsible for coordinating signaling process Wnt/B-catenin evolutionary pathway and therefore cell proliferation differentiation in tumor cells. We aimed study this marker different types gastric adenocarcinomas find its relationship with histopathologic features tumor. Methods This cross-sectional was performed on patients adenocarcinoma (diffuse or intestinal type) whose...
Lymphovascular tumoral invasion is a typical histopathological feature of gastric carcinomas and supports the recognition high-risk patients for recurrence. We aimed to study CD31 expression in diverse subtypes show its association with histopathologic findings carcinoma assess prognosis.This cross-sectional was conducted on 40 established adenocarcinoma from radical gastrectomy. The were classified according pathology assessments. Tumoral tissues assessed by immunohistochemical staining...
Application of central venous catheters become more common however a rare complication, embolization, can occur which lead to high mortality rate. Therefore, cardiovascular foreign bodies should be immediately remove with safe and effective method algorithm. So, we investigate the results body retrieval in our center based on designed In this case series study, patients who had embolization were managed by Our approach was time duration system also its location.
