Mixed Adeno-Neuroendocrine Carcinoma; Case Series of Ten Patients with Review of the Literature

Aims: Mixed adeno-neuroendocrine carcinoma is a rare entity, diagnosed with immunohistochemical studies. Literature mainly includes case reports and series which are very few. In our study, we aimed to report a case series from a tertiary hospital with demographics of the patients, detailed tumor and clinical findings and follow-up plus survival conditions. Methods: Pathology database was explored for patients with the pathological diagnosis of 'mixed adeno-neuroendocrine carcinoma' and patients were identified retrospectively and evaluated in means of demographics, histopathological examination, tumor properties. Results: Ten patients had been diagnosed with mixed adeno-neuroendocrine carcinoma in our center, diagnosed at a mean age of 64.7. Stomach was found to be the most common localization. Five patients (50%) were diagnosed as grade 3. Following surgery, median follow-up was 15 months with a median survival time of 20.6 months. Conclusion: This case series may contribute to the literature on the pathological and clinical aspects of the mixed adenoneuroendocrine carcinoma of the gastrointestinal system.

Importance of the neutrophil-to-lymphocyte ratio in muscle-invasive and non-muscle invasive bladder tumors.

INTRODUCTION: To research the importance of the neutrophil-to-lymphocyte ratio (NLR) in muscle-invasive bladder cancers (MIBC) and non-muscle invasive bladder cancer (NMIBC). METHODS: Data of 198 patients who underwent TUR-TM in our clinic were retrospectively evaluated. Patients were divided into two groups: group-I (MIBC) and group-II (NMIBC). The neutrophil and lymphocyte counts, NLR, hemoglobin and hematocrit values, tumor numbers, sizes and degrees of patients were recorded. Within the inter-group comparison, Mann-Whitney U test was used for the values stated with measuring, whereas a Chi-square test was used for the values stated with counting. The cut-off value for the NLR was determined with ROC curve. RESULTS: The NLR values of group-I and group-II were found as 4.14 ± 2.76 and 3.36 ± 2.88, respectively (p = 0.03). Whether the NLR carries a differential property was evaluated with ROC curve. The cut-off value was estimated as 3.96 according to the Youden index. With this value, sensitivity was found as 50%, specificity was 22.8% and AUC was 0.615 (p = 0.03). DISCUSSION: According to the data in this study, it can be said that Ta-T1 tumors are likely to be invasive by 50% if the NLR value is greater than 3.96.

[Giant renal cystic echinococcosis: case report]. / Dev Böbrek Kistik Ekinokok Hastaligi: Olgu Sunumu.

Echinococcosis is endemic in many parts of the world. Although echinococcosis can be present in all parts of the human body, urinary tract involvement develops in only 2-4% of all cases, and isolated renal cysts are extremely rare. There are no specific clinical symptoms or signs that will reliably confirm the diagnosis of renal echinococcosis. Routine blood tests are generally normal except for eosinophilia, which is found in only 20% of the cases. Radiological studies have a more important place in the preoperative diagnosis of renal hydatic disease. However, there is no specific sign on plain urography or intravenous urography, and ultrasound or computed tomography cannot always show a echinococcosis as a specific lesion. Echinococcosis should be included in the differential diagnosis of cystic lesions in solid organs or other anatomic sites, especially in endemic countries. We presented a patient with isolated giant renal cystic echinococcosis mimicking a complicated cyst who was treated successfully with nephrectomy.

Sclerosing cholangitis-like changes in hepatobiliary tuberculosis.

Atypical presentations of tuberculosis might cause difficulties in diagnosis, especially in developing countries. Primary hepatobiliary tuberculosis is a rare condition and the diagnosis of this condition necessitates a high index of suspicion. In this report, we present a case with obstructive jaundice, dilated intrahepatic bile ducts and lymphadenopathies in the porta hepatis. Endoscopic retrograde cholangiopancreaticography showed irregularities, strictures and dilatations both in the intra- and extrahepatic bile ducts resembling sclerosing cholangitis. The liver biopsy showed caseous granulomatous hepatitis and Langhans giant cells compatible with tuberculosis, and a lymph node biopsy obtained from the left cervical region demonstrated caseating confluent granulomas with abundant acid-fast bacilli. The present case shows that primary hepatobiliary tuberculosis may mimic primary sclerosing cholangitis and should be considered in the differential diagnosis of patients with sclerosing cholangitis-like changes on endoscopic retrograde cholangiopancreaticography.

Diffuse colorectal angiodysplasia misdiagnosed preoperatively as ulcerative colitis in a child: report of a case.

Angiodysplasia is primarily a disease of the elderly, and it is rarely encountered in the pediatric population. We report a case of diffuse colorectal angiodysplasia, diagnosed postoperatively in a 13-year-old boy who underwent hand-assisted laparoscopic total proctocolectomy and ileal pouch anal anastomosis (IPAA) for assumed corticosteroid-resistant ulcerative colitis. The findings of preoperative repeated colonoscopies and biopsies had been consistent with active colitis. Distinguishing ulcerative colitis from angiodysplasia is not usually difficult in patients with rectal bleeding. To our knowledge, this is the fi rst case report of such a challenging diagnostic problem.

Rectal angiolipoma: a case report and review of literature.

Angiolipoma is a rare vascular variant of the benign lipomatous tumors and is generally seen in subcutaneous tissues. We report a 70-year-old female with abdominal distension not related to rectal small polypoid mass with peduncule described as angiolipoma by histologically, and review the literature.

A rare cause of sudden vision loss in a young male: papillary fibroelastoma of the aortic valve.

Cardiac papillary fibroelastoma (CPF) is a rare cardiac neoplasm predominantly affecting the cardiac valves. Although it is most commonly an incidental finding, it can result in life-threatening complications, such as coronary and cerebral embolism, acute valvular dysfunction, and sudden death. In this report, we describe a case of a patient with aortic valve papillary fibroelastoma, which presented with sudden vision loss due to branch retinal artery occlusion. To the best of our knowledge, this is the third case of CPF-related retinal artery embolism in English literature.
