Chronic subdural hematoma (CSDH) is a common neurologic disease among the elderly. Spontaneous intracerebral hemorrhage (SICH) associated with CSDH has been reported as a rare complication. In most cases they develop during or after burr hole drainage, and are related to rapid decompression. Coagulopathy, vascular malformation, aneurysm, and neoplasm have been reported as other possible caution...

BACKGROUND The co-occurrence of intracranial arteriovenous malformations (AVMs) and cerebral neoplasms is exceedingly rare but may harbor implications pertaining to the molecular medicine of brain cancer pathogenesis. CASE DESCRIPTION Here, we present a case of de novo AVM within an isocitrate dehydrogenase 1 mutated anaplastic oligodendroglioma (WHO Grade III) and review the potential contri...

The histological boundary between benign and malignant vascular tumors is not clear. Thus, the discrepancies between clinical judgement and pathological diagnosis often lead to a difficult clinical decision, and may result in misdiagnosis. In order to develop more effective treatment methods, the clinical and pathological data concerning rare vascular tumors should be comprehensively analyzed. ...

Retiform hemangioendothelioma (RH) is an uncommon vascular neoplasm of borderline malignancy that clinically develops as a solitary, gradually enlarging exophytic mass, nodule or plaque, most often on the lower limbs, upper limbs and trunk. Clinical recognition of RH is troublesome because of its non-specific appearance, with differential diagnosis comprising a variety of benign and malignant t...

Hemangioma, the most common tumor of infancy, is a benign vascular neoplasm of unknown etiology. We show, for the first time to our knowledge, that endothelial cells from proliferating hemangioma are clonal, and we demonstrate that these hemangioma-derived cells differ from normal endothelial cells in their rates of proliferation and migration in vitro. Furthermore, migration of hemangioma endo...

Lipoma is the most common neoplasm of mesenchyme, and several subtypes have been described that vary according to their location and the presence of other tissue elements. Angiomyxolipoma is a very rare variant that consists of an admixture of adipose and myxoid elements with numerous vascular structures. It should be differentiated from other subtypes of benign and malignant lipomas. Here the ...

We report a rare case of venous hemangioma (VH) of the anterior mediastinum in a 56-year-old man admitted to our hospital because of hematemesis. Systemic examinations were performed and chest computer tomography (CT) revealed a 1.5-cm sized small nodule with contrast enhancement in the thymus. Both CT and magnetic resonance imaging (MRI) suggested a solid tumor such as a thymoma or neurogenic ...

Kaposiform hemangioendothelioma is a rare vascular tumor and locally aggressive endothelial-derived spindle cell neoplasm, which occurs almost exclusively in infants and adolescents. Radiologically, hemangioendothelioma, including Kaposiform hemangioendothelioma, is seen as a highly vascularized well-enhancing tumor, but no characteristic findings differentiate Kaposiform hemangioendothelioma f...

Basal cell adenocarcinoma (BCAC), the malignant counterpart of basal cell adenoma, is a rare salivary gland neoplasm, the most common site being parotid gland. It has been classified as a low-grade tumor with a favourable prognosis. Only a few cases have been reported to occur in submandibular gland. This report describes a case of right submandibular swelling which was diagnosed as a vascular ...
