OBJECTIVE: Scholars have gradually come to appreciate the relevance of serine and glycine metabolism. Recently, researchers have discovered that mitochondrial serine hydroxymethyltransferase 2 (SHMT2) is overexpressed in various types of cancer. However, the function of SHMT2 in glioma is not clear. In this study, we sought to examine the expression of SHMT2 in glioma, the association between SHMT2 expression and clinicopathological characteristics, and the association of SHMT2 expression with prognosis in glioma patients...

Mature cystic teratoma (MCT) is the most common neoplasm of the ovary and includes at least two well- differentiated germ cell layers. Different combinations of mature tissue derivatives with varying arrangements in the tumour cause a wide spectrum of radiological presentation ranging from a purely cystic mass to a complex cystic mass with a considerable solid component. In different imaging modalities, each radiological feature reflects a specific pathologic equivalent that forms because of diverse compositions of histological components...

Human papillomavirus (HPV), in addition to smoking and alcohol, is a cause of oropharyngeal squamous cell carcinoma (OPSCC), particularly of the tonsils and base of the tongue (TSCC and BOTSCC, respectively). Moreover, HPV-positive TSCC and BOTSCC are associated with a better outcome compared with their HPV-negative counterparts (80 vs. 40% 3-year disease-free survival rate, respectively) and their incidence has increased in several countries. Recently, accumulating evidence of HPV in a considerable proportion of cancers of unknown primary (CUP) in the head and neck region and in a small proportion of hypopharyngeal SCCs has been reported...

INTRODUCTION: Lynch syndrome is the most common form of hereditary colorectal cancer, being also responsible for endometrial and other types of cancers. It is associated with germline mutations in DNA mismatch repair genes and microsatellite instability. MLH1 and MSH2 mutations have a "classical" Lynch syndrome phenotype, with MSH2 having a higher association with extracolonic cancer. MSH6 and PMS2 mutations have an atypical phenotype. Clinical expression is heterogeneous, with correlation between mismatch repair mutated gene and phenotypic patterns...

Anti-N-methyl-d-aspartate-receptor (NMDAR) encephalitis is an uncommon autoimmune disorder with a wide spectrum of neuropsychiatric symptoms. There is a great requirement to emphasize the importance of a multidisciplinary team approach in the process of diagnosis and treatment of the potentially fatal condition, including psychiatrists, neurologists, gynaecologists and intensivists. Physicians must be aware that psychiatric and neurological disorders, which are typical features for NMDAR encephalitis in young women with ovarian tumours, may progress into status epilepticus and respiratory insufficiency...

Chemoradiotherapy and/or surgery are both potentially radical treatments for squamous cell carcinomas. Squamous cell carcinomas are considered chemosensitive tumours compared to adenocarcinomas or anaplastic thyroid malignancies. A 76-year-old man was found to have T4bN0M0 primary squamous cell carcinoma of the thyroid with encasement of the internal carotid artery. The disease was deemed unresectable. Therefore, he was treated with radical radiotherapy with concurrent cisplatin-based chemotherapy. We discuss herein the aetiology, diagnosis and management of primary squamous cell carcinoma of the thyroid...

Digital ischemia is a rare paraneoplastic phenomenon associated with several malignant tumours, particularly adenocarcinomas. The underlying pathogenic mechanisms remain unknown and it can be the first manifestation, occur after the diagnosis or during treatment. We report a case of a 50 year old woman presenting with digital ischemia, whose diagnostic workup led to an invasive breast cancer, with significant improvement of digital ischemia after a successful treatment of the neoplasm.

Neurofibromatosis type 2 (NF2) is a rare genetic disorder that occurs in an estimated one in 35,000 people. The condition is often life-limiting and involves tumours growing on the nervous system, typically on the hearing nerves, brain and spine. While the tumours are mainly benign, they can lead to hearing loss, deafness and problems with balance and mobility. Most patients will need surgery or other treatments for NF2-related brain or spinal cord tumours at some point in their lives.

Melanoma in young children is rare, however its incidence in adolescents and young adults is rising. We describe the clinical course of a 15-year-old female diagnosed with AJCC stage IB non-ulcerated primary melanoma, who died from metastatic disease four years after diagnosis despite three lines of modern systemic therapy. We also present the complete genomic profile of her tumour and compare this to a further series of 13 adolescent melanomas, and 275 adult cutaneous melanomas. A somatic BRAF(V)(600E) mutation and a high mutational load equivalent to that found in adult melanoma, and composed primarily of C>T mutations was observed...

Jenny Li, Nicholas Power
Testicular cancer is the most common cancer diagnosis in males aged 15-30 years. For over a century, radical inguinal orchiectomy has been the standard of care for initial treatment of testicular cancer. This approach is preferred over trans-scrotal interventions, in an effort to avoid tumour seeding, spermatic cord invasion, and disturbance to lymphatic drainage. Scrotal violation is defined as any trans-scrotal intervention that may impact spread of disease in testicular cancer, including scrotal orchiectomy, fine-needle aspiration, and testicular biopsy...

INTRODUCTION: Transient jejunal intussusception in an adult is a rare clinical finding as reported in the English literature. The diagnosis is usually a matter of exclusion given the extremely rare nature of this medical condition. PRESENTATION OF THE CASE: A young female presented to our hospital with abdominal pain and distention of six months duration. The episodes were intermittent in nature and resolved with conservative management. The aetiology remained obscure until a computerized tomography(CT) scan diagnosed a small bowel intussusceptionIntraoperatively a small bowel tumour was identified and resected...
