Askin tumor

Askin E Hasturk, Teoman Etikcan, Suat Canbay
Ependymomas are the most common gliomas of the conus and lower cord, with the cervical cord being the second most common location. These tumors can extend upward 3-4 vertebra, and some ependymomas can extend up over 15 segments. Depending on many factors, such as tumor size, lateralization, kyphotic deformity, and lordosis state, there are several posterior surgical options, including laminectomy, laminectomy and lateral mass screw-plate, and laminoplasty. In this study, we discuss a case of intradural intramedullary cervicothoracic ependymoma with long-segmental localization, as well as the general surgical principles of its excision with step-by-step demonstrative figures...

BACKGROUND: Women with recurrent ovarian cancer have a poor prognosis and short survival. However, some women are long-term survivors and it is unclear whether they share specific common characteristics. CASE REPORT: We present the case of a 63-year-old woman with histologically-proven recurrent ovarian cancer and a survival time of 16 years after the diagnosis of recurrence. She underwent initial debulking surgery in 1994, followed by 6 cycles of adjuvant chemotherapy with cisplatin and paclitaxel...

A young male labourer developed pain at the site of blunt trauma over back of chest followed by fever, cough with expectoration, breathlessness and hemorrhagic pleural effusion in the side of injury. What could have been passed as a sequel of trauma turned out to be the consequences of an underlying rare and aggressive malignant tumor of the chest wall known as Askin tumor or Primitive Neuroectodermal Tumor (PNET). CT thorax with guided FNAC, debulking operation, histopathological examination followed by immunohistochemistry of the tumor tissue led to the final diagnosis...

BACKGROUND: Fine-needle aspiration (FNA) biopsy of lung lesions is a highly accurate method for diagnosing and staging of lung cancers, particularly in patients with advanced cancer. Although, the majority of FNA cases of non-small cell lung carcinoma (NSCLC) can be subclassified by hematoxylin and eosin (H&E) sections, immunohistochemical (IHC) markers are usually necessary for difficult cases. Our previous study has shown that both P40 and P63 demonstrate differential sensitivity and specificity in the subclassification of squamous cell carcinoma (SqCC) using tumor tissue microarrays (TMA)...

Ewing's sarcoma/primitive neuroectodermal tumor/Askin's tumor (Ewing`s sarcoma family of tumors: ESFT) is the most common type of malignant tumor of bone and soft tissue in children and young adults, and morphologically is a member of a group of small round cell tumors. We report, here, on the establishment of two human ESFT cell lines, FU-PNET-3 and FU-PNET-4, from the iliac and the chest wall, respectively, the cells of both cell lines were tumorigenic in immunodeficient mice. Histologically, both original and xenograft tumors and cultured cells were composed of small round cells with positive immunoreactivity for CD99 and Nkx2...

BACKGROUND: Distinction between tumor and treatment related changes is crucial for clinical management of patients with high-grade gliomas. Our purpose was to evaluate whether dynamic susceptibility contrast-enhanced (DSC) and dynamic contrast enhanced (DCE) perfusion-weighted imaging (PWI) metrics can effectively differentiate between recurrent tumor and posttreatment changes within the enhancing signal abnormality on conventional MRI. METHODS: A comprehensive literature search was performed for studies evaluating PWI-based differentiation of recurrent tumor and posttreatment changes in patients with high-grade gliomas (World Health Organization grades III and IV)...

Primitive neuroectodermal tumors (PNETs) are highly malignant small round blue cell tumors of neuroectodermal origin belonging to either central nervous system, autonomic nervous system or peripheral Askin's or Ewing's group of neoplasms. The latter generally arise in soft tissues of trunk or axial skeleton in children and early adolescents. However in adults this entity is very uncommon. Of all peripheral entities, primary PNET of lungs without chest wall or pleural involvement in adults are extremely rare and have been scarcely reported in world literature as single case reports...

The Ewing sarcoma family of tumors (ESFT) encompasses a group of highly aggressive, morphologically similar, malignant neoplasms sharing a common spontaneous genetic translocation that affect mostly children and young adults. These predominantly characteristic, small round-cell tumors include Ewing's sarcoma of the bone and soft tissue, as well as primitive neuroectodermal tumors (PNETs) involving the bone, soft tissue, and thoracopulmonary region (Askin's tumor). Extraosseous ESFTs are extremely rare, especially in the head and neck region, where literature to date consists of sporadic case reports and very small series...

BACKGROUND: Adult granulosa cell tumor of the ovary (AGCT) is a rare functional sex-cord-stromal ovarian neoplasm characterized by low malignant potential and late relapse. Evidence-based management options for women with recurrent AGCT are limited. CASE REPORT: We present the case of a 60-year-old woman with the fifth recurrence of AGCT initially diagnosed 19 years ago. After initial surgery in 1996, the patient underwent four additional surgical interventions for recurrent disease in 2005 (abdominal wall), 2009 (abdominal wall), 2010 (paravesical), and 2011 (paravesical)...

Askin's tumor is a primitive neuroectodermal tumor (PNET) developing from the soft tissues of the chest wall and mainly occur in children and adolescents. The management approach is complex and requires a multidisciplinary team. We report a case of locally advanced Askin's tumour in a child because of its rarity and also to highlight the importance of keeping the possibility of PNET tumours in mind while dealing with cases of chest wall tumour in children.

Askin tumor is a rare neoplasm of thoracopulmonary region. But it mimics other common pediatric disorders, such as empyema, lymphoma, and tuberculosis, posing a great diagnostic and therapeutic challenge to the treating clinicians. So it is of utmost importance to make an early diagnosis and proper referral/treatment in such cases. We highlighted diagnostic challenge, treatment, and favorable outcome of a case that presented to us.

Personalized treatment of lung cancer requires an accurate subclassification of non-small cell lung carcinoma (NSCLC) into adenocarcinoma (ADC), squamous cell carcinoma (SqCC), and other subtypes. In poorly differentiated tumors especially on small fine-needle aspirate specimens, the subclassification could be difficult in certain cases. Our previous study using resected tumor tissue has shown that the combination of commonly used individual markers (thyroid transcription factor 1 [TTF-1], P40, and Napsin A) into a novel triple marker has high sensitivity and specificity in subclassification of NSCLC and also the advantage of using minimal tumor tissue...

PURPOSE: Adolescent and young adult (AYA)-aged central nervous system (CNS) tumor survivors are an understudied population that is at risk of developing adverse health outcomes, such as obesity. Long-term follow-up guidelines recommend monitoring those at risk of obesity, thus motivating the need for an eating behavior questionnaire. An abbreviated online version of the Three-Factor Eating Questionnaire (TFEQ-R18v2) has been developed, but its applicability to this population is not yet known...

Askin's tumor is a peripheral primitive neruoectodermal tumor within the thoracopulmonary region, which primarily occurs in children and young adults. In addition, Askin's tumor is commonly misdiagnosed, as it is rare and easily mistaken for other small round-cell tumors. The present study aimed to investigate the clinical characteristics, prognostic factors and treatment outcomes of patients diagnosed with Askin's tumor. Computed tomography (CT) scans, histopathology and immunohistochemical analysis were used for diagnosis...

In this retrospective study, surgical results of four patients with sacral tumors having disparate pathologic diagnoses, who were treated with partial or total sacrectomy and lumbopelvic stabilization were abstracted. Two patients were treated with partial sacral resection and two patients were treated with total sacrectomy and spinopelvic fixation. Fixation methods included spinopelvic fixation with rods and screws in two cases, reconstruction plate in one case, and fresh frozen allografts in two cases. Fibular allografts used for reconstruction accelerated bony union and enhanced the stability in two cases...

High-dose therapy (HDTx) with autologous stem cell rescue has been widely applied in very-poor-risk pediatric solid tumors. Promising data have become available with the use of high-dose busulfan, whereas high-dose (HD) thiotepa is less commonly used. We report retrospectively our single-institution experience from 1986 to 2012 of single and tandem HDTx with special emphasis on HD-thiotepa as the backbone of HD regimen in Ewing family tumors, including all 24 patients in the Helsinki University Hospital referral area in population-based fashion (Ewing sarcoma 9, Askin tumor 9, peripheral neuroectodermal tumor 6)...

BACKGROUND: Ewing sarcoma peaks in incidence in adolescence. Infants <12 months old have rarely been reported. We aimed to compare clinical features, treatment, and survival of infants <12 months to those of older pediatric patients with Ewing sarcoma. PROCEDURE: We utilized the SEER database to identify patients <12 months of age diagnosed with Ewing sarcoma between 1973 and 2011. We used Fisher exact tests to compare clinical features and treatment modalities between these patients and patients aged 1-19 years...
