Lymphatic, venous, and mixed lymphovenous malformations are low-flow lesions that are present at birth and grow proportionately with the patient. We describe an unusual presentation of a lymphovenous malformation in an adult. A 19-year-old man presented to the emergency department with complaints of recent upper respiratory tract symptoms, increasing left-sided ...

Deep arteriovenous malformations of the basal ganglia and thalamus have an aggressive natural history and present a therapeutic challenge. More often than not, these lesions are deemed "inoperable" and are treated expectantly or with stereotactic radiosurgery. In some cases, clinical details combined with an opportune route of access dictate surgical ...

Angioma serpiginosum is an uncommon, acquired vascular nevoid disorder with capillary dilation and proliferation in the papillary dermis. The eruptions are asymptomatic and characterized by grouped, erythematous to violaceous, serpiginous and punctate macules. The condition usually appears in females during adolescence on unilateral lower extremities and the buttocks. We report ...

Intravenous lobular capillary hemangioma is a rare benign lesion that can mimic other intravascular lesions encountered by vascular surgeons, such as angiosarcoma, papillary endothelial hyperplasia, and deep vein thrombus. These lesions have been described originating in the veins of the head, neck, and upper extremities. To our knowledge, there are ...

Vascular dementia/vascular cognitive impairment (VaD/VCI) is not a single entity, but a large group of conditions characterized by various clinical and morphological findings and variable pathophysiology. Clinical diagnostic criteria show moderate sensitivity (50-70%) and variable specificity (64-98%). Epidemiological studies are hampered by the lack of clear and validated diagnostic criteria, ...

The prevalence, morphology and pathogenesis of vascular dementia (VaD), recently termed vascular cognitive disorder (VCD), are a matter of discussion.VaD is suggested in 8-15% of cognitively impaired aged subjects. Its prevalence in autopsy series ranges from 0.03 to 58% (mean 8-15% in Western series, 22-35% in Japan). Neuropathology shows multifocal ...

The International Society for the Study of Vascular Anomalies (ISSVA) divides congenital vascular anomalies into malformations and tumors and subclassified hemangiomas under tumors. However, evidence shows this accepted classification has not been widely employed. Particularly troublesome is the use of the term hemangioma, commonly used to describe a variety of ...

Intramuscular cavernous hemagiomas represent <1% of all hemangiomas and consist of benign proliferations of blood vessels. Typical presentation is an enlarging painful soft-tissue mass without cutaneous changes. Intramuscular cavernous hemangiomas do not undergo spontaneous regression and may be locally destructive because pressure is exerted on neighboring structures. Phleboliths on radiograph ...

BACKGROUND: Paroxysmal nocturnal hemoglobinuria (PNH) is characterized by the classic triad of haemolytic anaemia, thrombophilia and cytopenia with the majority of cases occurring in adulthood. PNH constitutes a nonmalignant clonal disease of hematopoietic stem cells harboring somatic mutations in the X-linked phosphatidyl inositol glycan complementation group-A (PIG-A) gene. METHODS: We ...

Enzymes of the matrix metalloproteinase (MMP) family regulate angiogenesis and are involved in the endochondral ossification process. Tibial dyschondroplasia (TD) and rickets are 2 disorders associated with impairments in this process, mainly in the vascularization of the avian growth plate. In this paper, we induced TD and rickets and studied ...

Angiokeratoma is a benign vascular lesion. It is the result of dilation of ectatic subdermal vessels and congested capillaries. Weakness of the vessel walls, either from acquired or congenital reasons, can cause formation of the lesion. Angiokeratoma is more common in males, in whom it forms on the scrotal wall. ...

Verrucous hemangioma (VH) is a hyperkeratotic lesion usually presenting in infancy, occurring primarily on the extremities. We report a 5-year-old boy with VH in the glans penis and discuss briefly the hyperkeratotic vascular stains, which constitute a heterogenous group. During a 7-year follow-up, the patient received various local treatments, but ...

BACKGROUND: Optical coherence tomography (OCT) is a new non-invasive approach for real-time in vivo tissue characterization. A promising use of OCT can be the assessment of the architecture of lesions with some degree of inhomogeneities, such as vascular lesions. Knowledge of the size and depth of the vascular structures can ...

Mondor's disease (MD) is considered an inflammatory condition of superficial vasculitis that develops mainly in the anterolateral thoracoabdominal wall. The pathogenesis of the disease has been controversial, however, because of the lack of histopathologic methods for differentiating between the small vein and the lymphatic vessel. To objectively examine the origin ...

Pulmonary vascular malformations have historically been diagnosed in a wide range of age groups, but the extensive use of prenatal imaging studies has resulted in the majority of lesions being diagnosed in utero. Among this group of lesions, bronchopulmonary sequestrations (BPS), hybrid lesions with both congenital cystic adenomatoid malformation (CCAM) ...

Vascular malformations are localized or diffuse errors of embryonic development resulting in collections of abnormal vessels with normal endothelium. Many authors have pointed out the confusing terminology of vascular anomalies that has led to improper diagnosis and therapy. This still remains confused in clinical practice, especially in cases occurring at ...

Vascular birthmarks can be classified into hemangioma and vascular malformations. Hemangioma are frequent tumours of early infancy demonstrating endothelial hyperplasia, a history of rapid neonatal growth and slow involution during later childhood. Treatment of hemangioma is dependent of stage and type of the lesion. Given the current availability of drugs, ...

BACKGROUND: Small-intestinal vascular lesions observed by endoscopy vary in appearance. Angioectasia is a venous lesion that requires cauterization; a Dieulafoy's lesion and arteriovenous malformation may cause arterial bleeding, which requires clipping or laparotomy. For selection of the appropriate treatment, it is necessary to distinguish between venous and arterial lesions. PATIENTS ...

Vascular benign lesions are the most common non-hematological splenic primary tumors. Although rare they may sometimes pose problems in differential diagnosis, because of their morphologic heterogeneity. We present vascular lesions of the spleen, which were found in archive of the Chair of Pathomorphology. Immunohistochemistry including CD34, CD31, factor VIII, CD8, ...
