Penile tumours are an important problem of male health affecting physical, mental and sexual health. Penile tumours can be subdivided into benign and malignant lesions. Their knowledge is important to prevent mutilating surgery in benign lesions. On the other hand, early recognition of malignancies is important for improved prognosis, and ...

BACKGROUND: Whether early Barrett's neoplasia has a predilection for particular spatial locations in shorter segment disease is currently unknown. Anatomic factors may play a role in lesion location because of differing levels of mucosal acid exposure. OBJECTIVE: To identify high-risk lesion locations, which has important implications for surveillance strategies. DESIGN: ...

A 2-year-old male Welsh corgi dog was brought to an animal hospital because of left upper eyelid enlargement with lachrymal gland protrusion. The lachrymal and orbital cavity mass was removed surgically. Microscopically, the orbital mass consisted of a mixture of large rhabdomyoblastic and small round tumour cells. Immunohistochemically, the rhabdomyoblastic ...

This review provides a state-of-the-art knowledge on the implications of microRNA (miRNA) dysregulation in lymphoid malignancies. Several new studies have broadened our understanding of how aberrations of the miRNome contribute to the development of a malignant lymphoid phenotype. Recently, a new pathogenetic model involving miRNAs and protein coding genes (such ...

Timely and accurate diagnosis of hematologic malignancies is crucial to appropriate clinical management. Acute leukemias are a diverse group of malignancies with a range of clinical presentations, prognoses, and preferred treatment protocols. Historical classification systems relied predominantly on morphologic and cytochemical features, but currently, immunophenotypic, cytogenetic, and molecular data are ...

Carcinoid tumours are well-differentiated neuroendocrine tumours with secretory properties. Although fairly rare, they are the most common malignancy seen to affect the distal small bowel. Presentation is often non-specific with symptoms mimicking those of irritable bowel syndrome. Given this, the condition is often diagnosed late following disease progression, by which ...

Hemiballism is most commonly caused by ischemic stroke and most cases have a favorable prognosis. Lesions directly involving the subthalamic nucleus (STN) are the cause of a minority of cases but are usually associated with poor prognosis. We report two patients with a small STN lesion who presented with transient ...

Mucoid impaction is a relatively common finding at chest radiography and computed tomography (CT). Both congenital and acquired abnormalities may cause mucoid impaction of the large airways that often manifests as tubular opacities known as the finger-in-glove sign. The congenital conditions in which this sign most often appears are segmental ...

Cholangiocarcinoma is the second most common primary malignant hepatobiliary neoplasm, accounting for approximately 15% of liver cancers. Diagnosis of cholangiocarcinoma is challenging and the prognosis is uniformly poor, with recurrence rates of 60%-90% after surgical resection. A wide spectrum of neoplastic and nonneoplastic conditions of the biliary tract may masquerade ...
