Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...

61 Abstract. – Cervical paragangliomas are uncommon benign or malignant neoplasms, originated by stem cells of neural crest. It is not easy nowadays to define properly their biological behaviour, the possible multiple location and the association with Multiple Endocrine Neoplasms. After a wide review about recent diagnostic, pathological and clinical acquisition, authors report their caseload o...

Extracellular tumors found with the spermatic cord, known as neoplasms, are usually identified to be benign. However, the accurate and timely diagnosis of spermatic cord masses is highly crucial, especially when most results are often overlooked or unclear. In this review, we discuss the anatomy and embryology of the spermatic cord. Upon rooting these fundamental concepts, we discuss an array o...

Neurovascular Disorders Neurovascular disorders encompass those conditions that result in cerebrospinal ischemia, infarction, and hemorrhage. Various vascular and parenchymatous changes have been reported in dogs and cats in association with vascular anomalies (e.g., aneurysms, telangiectatic hamartomas), cerebral arteriosclerosis, mineral and pigment deposition, malacias and necrosis, cerebral...

● Gastrointestinal stromal tumors are mesenchymal neoplasms with a spectrum of histologic appearances and biologic activity. The morphologic classification of these lesions has evolved over time, and molecular analysis has led to a better understanding of their nature. The histologic differential diagnosis for these lesions is broad and includes many spindle cell lesions of the gastrointestinal...

PURPOSE The aim of this study was to explore the feasibility of image classification of liver cancer surrounding right hepatic pedicle (RHP) and its guide to precise liver resection. METHODS Twenty-five patients with single liver cancer surrounding RHP were collected. According to the adjacent relationship between neoplasm and RHP shown in CT or MRI, the liver neoplasms were divided into the ...
