Analysis of lung adenocarcinomas for actionable mutations has become standard of care. Here, we report our experience using next generation sequencing (NGS) to examine AKT1, BRAF, EGFR, ERBB2, KRAS, NRAS, and PIK3CA genes in 1006 non-small cell lung cancers in a clinical diagnostic setting. NGS demonstrated high sensitivity. Among 760 mutations detected, the variant allele frequency (VAF) was 2-5% in 33 (4.3%) mutations and 2-10% in 101 (13%) mutations. A single bioinformatics pipeline using Torrent Variant Caller, however, missed a variety of EGFR mutations...

BACKGROUND: Primary melanoma of the vagina (PMV) is a rare entity. The prognosis of women with PMV is poor and there is no standardized therapy for this type of malignancy. We present the case of a 72-year-old woman with PMV (cT2, pN0, M0). CASE REPORT: Imaging studies showed no evidence of regional or distant metastases. Molecular analysis demonstrated wild-type B-Raf proto-oncogene, serine/threonine kinase (BRAF). Staging laparoscopy with pelvic lymphadenectomy and subsequent radiotherapy with 60 Gy delivered as pelvic teletherapy and vaginal brachytherapy was applied...

Recent large scale genomic studies from the Clinical Lung Cancer Genome Project have identified different driver gene mutations in the subtypes of non-small cell lung carcinoma (NSCLC). These findings not only lead to remarkable progress in targeted therapies for lung cancer patients, but also provide fundamental knowledge for the subclassification of NSCLC. More recently, the advancement and clinical application of immunotherapy have reinforced the need for the accurate subclassification of NSCLC. In 2015, the World Health Organization (WHO) and the International Association for the Study of Lung Cancer (IASLC) updated their guidelines for the subclassification of lung cancers...

INTRODUCTION: Anti-tumor necrosis factor (anti-TNF) treatments are effective in controlling disease activity in many immune-mediated diseases such as psoriasis and ankylosing spondylitis (AS). Although side effects such as infection and skin reactions are predictable in anti-TNF treatment; susceptibility to psoriasis is considered as a paradoxical side effect. CASE REPORT: We report a case of forty-year-old male patient with 7 years of AS was taking anti-TNF therapy...

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)...

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...

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.
