Vascular lesions of the head and neck include vascular neoplasms, vascular malformations, and hypervascular lesions, derived from nonvascular soft-tissue elements. We retrospectively evaluated magnetic resonance imaging and computed tomography images of vascular lesions located in the head and neck. Twelve patients (seven males, five females) aged 1-68 years (mean age, 35.25 years) were include...

The development of pulmonary metastases after local surgical control of malignant tumors has represented a major cause of treatment failure in a variety of neoplasms. The metastatic process has been a subject of considerable interest, investigation, and speculation for many years, but it remains as a poorly characterized and little understood phenomenon. The formation of blood-borne metastases ...

Splenic infarction is a rare diagnosis in the emergency department and can easily mimic other causes of acute abdomen. Cardioembolic hematological disorders, inflammatory (eg pancreatitis) infectious sepsis) conditions, postoperative malignant neoplasms atherosclerosis are some risk factors. Papillary thyroid carcinoma most common histologic type differentiated malignancy known as least aggress...

OBJECTIVE Matrix metalloproteinases (MMPs) and the angiogenic proteins basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) have been implicated in mechanisms of human cancer and metastasis. Assays were conducted on the urine of patients with vascular anomalies (tumors and malformations), relatively common and occasionally life-threatening disorders for which few ...

Introduction. Primary splenic angiosarcoma is an extremely unusual neoplasm originating from sinusoidal vascular endothelium. Surgical extirpation is the mainstay of treatment of this highly malignant disease. Case Presentation. An 82-year-old woman was admitted with left pleural effusion and a palpable left upper quadrant abdominal mass, secondary to splenomegaly by two large splenic tumors. C...

BACKGROUND Eccrine poroma is a benign neoplasm that can mimick a malignant neoplasm dermoscopically. The characteristic vascular pattern of this tumor has not been established. OBJECTIVE To evaluate dermoscopic features of non-pigmented eccrine poroma in Mexican patients. METHOD We retrospectively studied histologically proven cases of eccrine poroma from three Mexican hospitals analyzed by...

Glomus tumors were described by Rosenwasser in 1945 (1). Glomus body tumors, often abbreviated as glomus tumors, are also known as paragangliomas or chemodectomas. They are a family of benign hypervascular neoplasms arising from the chief cells of the paraganglionic tissues. Furthermore, glomus tumors have vascular structure, comprising cell bundles stained with non chromaffin among thin-walled...

Endothelial cells of the central nervous system over-express surface proteins during neurological disorders, either as a cause, or a consequence, of the disease. Since the cerebral vasculature is easily accessible by large contrast-carrying particles, it constitutes a target of choice for molecular magnetic resonance imaging (MRI). In this review, we highlight the most recent advances in molecu...
