We present a 71-year-old male, who had had a heart transplantation 24 years prior, who came to our clinic with a low-grade fever and a new II/VI holosystolic murmur. Echocardiography showed a large mass in the right atrium with attachment near the junction of the right atrium and superior vena cava. The patient was taken to the operating room for resection of the mass. Microscopic evaluation was consistent with thrombus. Differential diagnosis of cardiac masses after cardiac transplant includes tumour, thrombus, and vegetation...

Horner's syndrome (HS) occurs when there is disruption to the oculosympathetic pathway. Its features include eyelid ptosis, miosis and anhidrosis. The aetiology of this syndrome is varied and includes tumours, trauma, vascular disease and iatrogenic. Different pharmacologic tests are used for diagnosis, such as cocaine, hydroxyamphetamine and apraclonidine; while neuroimaging helps elucidating the aetiology. We present a case of a 63-year-old female referred to our service with a 4-month history of right eyelid ptosis...

BACKGROUND: In this study, we prospectively evaluate the diagnostic potential of a gallium-68 (68Ga) prostate-specific membrane antigen (PSMA)-binding ligand and positron emission tomography (PET) in detecting metastatic lesions in patients with renal tumour. The secondary aim was to determine whether the findings would result in the alteration of patient management. RESULTS: Ten patients with renal lesion and potential metastatic disease on conventional imaging were recruited...

BACKGROUND: Ankylosing spondylitis (AS) is an autoimmune rheumatic disease mostly affecting the axial skeleton. Currently, anti-tumour necrosis factor α (anti-TNF-α) represents an effective treatment for AS that may delay the progression of the disease and alleviate the symptoms if the diagnosis can be made early. Unfortunately, effective diagnostic biomarkers for AS are still lacking; therefore, most patients with AS do not receive timely and effective treatment. The intent of this study was to determine several key metabolites as potential biomarkers of AS using metabolomic methods to facilitate the early diagnosis of AS...

OBJECTIVES: To examine the added value of considering smooth hypointense rim in the hepatobiliary phase (HBP) of gadoxetic acid-enhanced MRI as capsule appearance for diagnosing tumour capsules and hepatocellular carcinoma (HCC). METHODS: A total of 377 hepatic lesions (330 HCCs, 35 non-HCC malignancies and 12 benign) were included from 345 patients who underwent resection after MRI between January 2008 and December 2011. Two radiologists assessed the presence or absence of conventional capsule appearance and smooth hypointense rim in the HBP, and categorized each hepatic lesion according to the Liver Imaging Reporting and Data System...

Urothelial carcinoma can exhibit a wide variety of histopathological phenotypes or variant morphologies, classifications of which have recently been revised in the 2016 WHO Classification of Tumours of the Urinary System and Male Genital Organs. Many of these variants not only present diagnostic challenges, but also have clinical implications that affect patient prognosis and treatment strategies. This review will discuss these variant morphologies and their relationship to current understanding of the underlying biology of urothelial carcinoma and molecular classification paradigms...

Malignant melanoma contributes the majority of skin cancer related deaths and shows an increasing incidence in the past years. Despite all efforts of early diagnosis, metastatic melanoma still has a poor prognosis and remains a challenge for treating physicians. In recent years, improved knowledge of the pathophysiology and a better understanding of the role of the immune system in tumour control have led to the development and approval of several immunotherapies. Monoclonal antibodies against different immune checkpoints have been revolutionizing the treatment of metastatic and unresectable melanoma...

BACKGROUND: Whilst multi-parametric magnetic resonance imaging (mp-MRI) has been a significant advance in the diagnosis of prostate cancer, scanning all patients with elevated prostate specific antigen (PSA) levels is considered too costly for widespread National Health Service (NHS) use, as the predictive value of PSA levels for significant disease is poor. Despite the fact that novel blood and urine tests are available which may predict aggressive disease better than PSA, they are not routinely employed due to a lack of clinical validity studies...

OBJECTIVE: To describe medical conditions associated with the use of CT in children or young adults with no previous cancer diagnosis. METHODS: Radiologists' reports for scans performed in 1995-2008 in patients <22 years of age were collected from the Radiology Information System in 44 hospitals of Great Britain. By semantic search, an automated procedure identified 192 medical conditions within the radiologists' reports. Manual validation of a subsample by a paediatric radiologist showed a satisfactory performance of the automatic coding procedure...

INTRODUCTION: Gemistocytic astrocytoma is the second most common subtype of World Health Organization grade 2 astrocytoma, but has a worse prognosis than other grade 2 lesions. We aim to describe the MR imaging features of histopathologically proven gemistocytic tumours. METHODS: Ethics approval was obtained from both institutions. Patient consent was not required for this retrospective study. We reviewed MR imaging findings of 16 consecutive cases of histopathologically proven gemistocytic astrocytoma and anaplastic astrocytoma with gemistocytic features...

Clonality studies greatly assist in the diagnosis of challenging haematopathology cases. These robust and standardised tests aid the detection of clonal lymphoid populations and may assist in lymphocyte subtyping. In this case report, a gentleman presented with a high-grade transformation of a B cell neoplasm which histologically and immunophenotypically mimicked a T cell anaplastic large-cell lymphoma. With the aid of T cell and B cell receptor clonality studies, it was demonstrated that this tumour was in fact of B cell lineage...

Merkel cell carcinoma is a rare primary cutaneous neuroendocrine tumour that is locally aggressive. In most cases the primary treatment is local surgical excision; however, there is a high incidence recurrence both local and distant. Cerebral metastases from Merkel cell carcinoma are extremely uncommon with only 12 cases published in the literature. This case is particularly unusual in that, not only was no established primary lesion identified, but also the patient has survived for 10 years following initial diagnosis and for 9 years following excision of a single brain metastasis...

Pilocytic astrocytomas (PAs) are the most frequent primary astroglial tumours affecting children and adolescents. They occur sporadically or in association with a genetically determined syndrome - neurofibromatosis type 1. Classic PA usually manifests as a well-circumscribed, often cystic, slowly growing tumour, which corresponds to WHO grade I. The majority of pilocytic tumours arise along the neuraxis, predominantly in the cerebellum. They are associated with favourable long-term outcome or spontaneous regression, even after incomplete resection...

BACKGROUND: Lesions involving the outer cortical surface of the bone occur quite often among children. Broadly, these include benign cortical, juxtacortical and periarticular lesions, dysplasias affecting the cortical bone, regional and diffuse periosteal pathology and malignant tumours. Some of these lesions are unique to the paediatric population; others are more frequently seen among children than adults - yet others have an adult predilection but can occasionally be seen in children...

Cervical cancer (CC) is one of the most common cancers among women worldwide. The relation of the human papillomavirus (HPV) with CC and its precursor lesions was first suspected for over 40 years. The indoleamine 2,3 dioxygenase (IDO) is an immune modulator enzyme responsible for the immune system tissue protection mechanism, which may be the key to the tumoural persistence. HPV oncoprotein E7 promotes the increase in cyclin-dependent kinase inhibitor p16 (CDKN2A/p16). The isolated and combined analysis of CDKN2A/p16 mRNA to CC diagnosis was done with promising results...

BACKGROUND: Prognostic factors and the standard treatment approach for gynaecological carcinosarcomas have not yet been clearly defined. Although carcinosarcomas are more aggressive than pure epithelial tumours, they are treated similarly. Serous/clear cell and endometrioid components may be predictive factors for the efficacy of adjuvant chemotherapy (CT) or radiotherapy (RT) or RT in patients with uterine and ovarian carcinosarcomas. Heterologous carcinosarcomas may benefit more from adjuvant CT...

Juvenile giant fibroadenoma is a very rare breast disease affecting young girls of premenarche and adolescent ages. It is a benign fibroepithelial tumour characterised by stromal and epithelial proliferation that causes rapidly growing breast mass. Bilateral symmetrical involvement is extremely rare. In this article, we describe this entity in a girl aged 13 years who presented with bilateral gigantically enlarged breasts. Ultrasonography and MRI showed large, multilobulated masses involving both breasts entirely...
