Ewing’s Sarcoma of the Peritoneum: a Rare Location for Extraskeletal Ewing’s Sarcoma

A 38-year-old male presented to the emergency department with abdominal pain and bulge. He had a history of irritable bowel syndrome for 1 year with complaint of dyspepsia. Physical examination revealed a distended abdomen with a huge palpable mass located in the paraumblical region. Laboratory findings revealed a high white blood cell count with neutrophil predominance. Contrast-enhanced computed tomography (CT) showed a 23-cm, oval-shaped, grossly necrotic, low-attenuation mass with peripherally located dominant vessels. Magnetic resonance imaging (MRI) with diffusion weighted imaging (DWI) suggested a highly malignant tumor with prominent diffusion restriction especially at the periphery of the mass. On surgery, macroscopic examination showed a macrolobulated, hypervascular, reddish brown mass attached to the parietal peritoneum with a stalk. Ewing’s sarcoma (ES) was diagnosed on histopathological examination with small round cells.     

An extremely rare manifestation of Behcet’s disease: urethrovaginal fistula

Behcet’s disease (BD) is a rare chronic, relapsing, multisystemic disorder characterized by mucocutaneous, ocular, vascular and central nervous system manifestations. However, the etiopathogenesis of the disease remains unknown, and diagnosis is basically dependent on clinical manifestations. Sometimes BD may be diagnosed with rare clinical entities. Herein, we presented an extremely rare case of urethrovaginal fistula which has been diagnosed as manifestation of BD. After surgical treatment of fistula, there was no complication in 6 months following surgical repair and the follow-up period has been going on.     

Jejunal perforation in mentally retarded patient due to an ingested chicken bone

We report a mentally retarded case with jejunal perforation by ingested chicken bone. Foreign body ingestion constructs a health threat for mentally retarded people. Under guidance of the literature, travel of the bones in the gastrointestinal tract, diagnosis and treatment strategies are evaluated.     

Investigation of UCH-L1 levels in ischemic stroke,intracranial hemorrhage and metabolic disorder induced impaired consciousness

Objective

We aimed to determine the levels of ubiquitin C-terminal hydrolase-L1 (UCH-L1) in patients admitted to the emergency department with impaired consciousness due to metabolic or neurological reasons.

Association of <Emphasis Type="Italic">Escherichia</Emphasis><Emphasis Type="Italic">coli</Emphasis> O157:H7 with necrotizing enterocolitis in a full-term infant

Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency of the neonate. NEC is predominantly seen in premature infants; however, in rare instances it can affect full-term infants as well. Although the pathogenesis of NEC remains elusive, it is well established that bacterial colonization is required for development of this disease. In this report, we present a case of a full-term infant, who developed a very aggressive form of NEC and was found to have Escherichia coli (E. coli) O157:H7 both in stool and blood cultures. Unfortunately, despite aggressive surgical and intensive care management, this infant suffered pan-intestinal necrosis and expired. We were not able to establish the route of transmission. To our knowledge, this is the first report of the association of E. coli O157:H7 with NEC.     

Malignant Struma Ovarii: A Case Report

We present a case of a 40-yr-old woman diagnosed with a primary malignant struma ovarii. The patient was admitted with the complaint of pelvic pain and a large pelvic mass in the mid-portion of lower abdomen on gynecological examination. Pre-operative tumor markers and routine biochemistry were unremarkable. She was treated with total abdominal hysterectomy and right salpingo-oopherectomy. Post-operatively, she was diagnosed with a malignant struma ovarii through the usage of histopathological criteria similar to the guidelines for primary thyroid gland disease. The patient was subsequently performed left salpingo-oopherectomy and retroperitoneal pelvic lympadenectomy for re-staging. Although, left ovary and lymph nodes were histopathologically normal, she was offered thyroidectomy but she refused to accept the offer. Thyroglobulin level was monitored in the post-operative period. She is free of the disease for 18 months.     

The Relationship of the BRAFV600E Mutation and the Established Prognostic Factors in Papillary Thyroid Carcinomas

It has been shown that BRAF(V600E) mutation in papillary thyroid carcinomas (PTC) is associated both with pathogenesis and poor prognosis. In this study, we aimed to investigate the relationship of the BRAF(V600E) mutation and the established prognostic factors in a cohort of Turkish patients with PTC. Forty-six cases of papillary thyroid carcinoma have been evaluated for the presence of BRAF(V600E) mutation. BRAF(V600E) has been examined by restriction fragment length polymorphism. BRAF(V600E) mutation status has been compared with well-known histopathological and clinical prognostic parameters such as invasion of thyroid capsule, extrathyroidal extension, and the presence of lymph node and/or distant metastasis. We have found that BRAF(V600E) mutation was present in the majority of our cases (40/46). Considering the stage of the disease, five of the negative cases were in stage 1 while the remaining one was in stage 2. Only one BRAF(V600E) negative case has shown extrathyroidal extension and lymph node metastasis. All four patients with distant metastasis had BRAF(V600E) mutation. Statistical analyses revealed that there are no significant relationship between the BRAF(V600E) mutation and the established prognostic factors. We found a relatively higher BRAF(V600E) mutation rate in classical type PTC than in other similar studies. We think that the limited number of our cases may either weaken or mask some potentially important relationship between BRAF(V600E) mutation and the established prognostic factors.
