Gastroesophageal (GE) malignancies make up a significant and growing segment of newly diagnosed cancers. Approximately 80% of patients who have GE cancers die within 5 years of diagnosis, which means that effective treatments for these malignancies need to be found. Currently, targeted therapies have a minimal role in this disease group. Intensive study of the molecular biology of GE cancers is a relatively new and ongoing venture, but it has already led to a significant increase in our understanding of these malignancies...

Leiomyosarcoma, a rare tumor subtype, accounts for 1% of all uterine malignancies, but contributes to a significant proportion of uterine cancer deaths. Surgery is considered the mainstay of treatment for all soft tissue sarcomas, including uterine variants. However, uterine leiomyosarcoma is challenging to diagnose preoperatively and can mimic the appearance of benign uterine leiomyomas. Recently, concerns have grown in this regard, as surgeons have utilized uterine morcellation and myomectomy procedures unknowingly in the setting of occult uterine sarcoma...

Tetralogy of Fallot (TOF) is the most frequently diagnosed congenital cyanotic heart disease. It is often associated with additional findings, such as atrial septal defect (i.e., pentalogy of Fallot) or right sided aortic arch. Association of this pentalogy of Fallot with situs inversus totalis is rarely reported in paediatric literature and it can cause technical challenges to intracardiac repair. We report the case of pentalogy of Fallot with dextrocardia and situs inversus presenting as parieto-occipital abscess in a 12-year-old child...

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a chronic affliction characterized by numerous liver and kidney cysts. There is a gradual but progressive renal and liver impairment which may require combined liver-kidney transplantation. Compression of the retrohepatic Inferior Vena Cava (IVC) by an enlarged polycystic liver may impede clear visualization on pre-operative imaging and miss an underlying thrombosis or obliteration. This may result in an intra-operative surprise. Management can be challenging requiring modification of conventional surgical approach...

Infective endocarditis by Methicillin Resistant Staphylococcus aureus (MRSA) bacteraemia is a common association and carries a high mortality. However, rising Minimum Inhibitory Concentrations (MICs) for vancomycin amongst MRSA strains is an emerging threat which carries poor prognosis and higher mortality. Here, we report a case of 41-year-old young non-addict gentleman presenting with fever of 3 days duration following recovery from an acute kidney injury necessitating haemodialysis. Systemic examination revealed signs of mitral regurgitation and left sided cerebellar signs...

Neurosurgical interventions are rarely associated with meningitis with a very low incidence rate ranging from 1.1% to 2.5%. Gram negative bacillary meningitis first described in the 1940's, previously uncommon has been increasing in the recent past associated with advanced age, immunosuppression and neurosurgery. Enterobacter meningitis though relatively uncommon is recently increasing in incidence and treatment is frequently complicated due to resistance to antibiotics making this a challenging, difficult to treat infection that may be associated with adverse clinical outcomes...

BACKGROUND: The cytology of oral squamous cell carcinoma (SCC) is challenging because oral SCC cells tend to be well differentiated and lack nuclear atypia, often resulting in a false negative diagnosis. The purpose of this study was to establish practical cytological parameters specific to oral SCCs. METHODS: We reviewed 123 cases of malignancy and 53 of non-neoplastic lesions of the oral mucosa, which had been diagnosed using both cytology and histopathology specimens...

BACKGROUND: Distinguishing a benign enchondroma from a low-grade chondrosarcoma is a common diagnostic challenge for orthopaedic oncologists. Low interrater agreement has been observed for the diagnosis of cartilaginous neoplasms among radiologists and pathologists, but, to our knowledge, no study has evaluated inter- and intraobserver agreement among orthopaedic oncologists grading these lesions using initial clinical and imaging information. Determining such agreement is important since it reflects the certainty in the diagnosis by orthopaedic oncologists...

: Thyroid cancer with cranial metastasis in a pregnant woman is very rare. In the literature, most cases are diagnosed early from neurogenic signs or symptomatic thyroid gland. Pregnancy also contributes to a hesitation toward early surgical and medical treatments. We reported a scalp tumor in a physically healthy 37-year-old pregnant female with a follicular thyroid carcinoma (FTC) with lung, bone and cranial metastasis in initial presentation. Silent neurogenic and physical examinations make an early diagnosis very challenging...

: A male patient presented at the age of 30 with classic clinical features of acromegaly and was found to have elevated growth hormone levels, not suppressing during an oral glucose tolerance test. His acromegaly was originally considered to be of pituitary origin, based on a CT scan, which was interpreted as showing a pituitary macroadenoma. Despite two trans-sphenoidal surgeries, cranial radiotherapy and periods of treatment with bromocriptine and octreotide, his acromegaly remained active clinically and biochemically...

Composite lymphoma (CL) is a rare disease with 2 distinct lymphomas concurrently arising in a single patient with an estimated incidence of 1-4.7% of newly diagnosed lymphomas per year. CL most commonly involves 2 B-cell non-Hodgkin lymphomas (NHL) or a B-cell NHL with a Hodgkin lymphoma. Our case is unique in that it was a bilineage CL with both a T-cell and B-cell NHL, which has only been reported in a few case reports. A 49-year-old woman presented with several months of progressive cough, weight loss, dyspnea, and supraclavicular lymphadenopathy...

Clonal complexity is increasingly accepted in Mycobacterium tuberculosis infection, including mixed infections by ≥2 strains, which usually occur in settings with a high burden of tuberculosis and/or a high risk of overexposure to infected patients. Mixed infections can hamper diagnostic procedures: obtaining an accurate antibiogram is difficult when the susceptibility patterns of the strains differ. Here, we show how mixed infections can also prove challenging for other diagnostic procedures, even outside settings where mixed infections are traditionally expected...
