BACKGROUND Vascular tumors of the kidney are rare tumors that are usually diagnosed and confirmed by histopathological examination due to the difficulty in definitive diagnosis by clinical and radiological examination. Anastomosing hemangioma is a rare variant of capillary hemangioma that mimics angiosarcoma. CASE REPORT Here, we present a case of a 55-year-old female with a history of partial ...

Hemangioma of the rib is a rare benign tumor that is often difficult to distinguish from malignant bone tumors. Rib hemangioma often shows bony disruption with a slight cortical disruption, extraosseous lesion, and expanded bone on computed tomography (CT). We report the case of a 68-year-old man with atypical rib hemangioma with a slight cortical disruption and no expanded bone. The tumor show...

Infantile hemangioma is an endothelial tumor that grows rapidly after birth but slowly regresses during early childhood. Initial proliferation of hemangioma is characterized by clonal expansion of endothelial cells (ECs) and neovascularization. Here, we demonstrated mRNA encoding CD133-2, an important marker for endothelial progenitor cells (EPCs), predominantly in proliferating but not involut...

Infantile hemangioma is a benign endothelial tumor composed of disorganized blood vessels. It exhibits a unique life cycle of rapid postnatal growth followed by slow regression to a fibrofatty residuum. Here, we have reported the isolation of multipotential stem cells from hemangioma tissue that give rise to hemangioma-like lesions in immunodeficient mice. Cells were isolated based on expressio...

Hemangioma is a common benign soft-tissue tumor; however, intramuscular hemangioma presenting with pathological fracture an infrequent occurrence. Imaging plays key role in diagnosing this entity. We report case of 30-year-old male who presented the left femur following trivial trauma. Clinical examination was remarkable for significant swelling which on further radiological investigation revea...

background: propranolol has been recently indicated to inhibit the rapid growth and involution of infantile hemangioma. in the present study, we investigated the efficacy and safety of propranolol in iranian infants. methods: a total of 30 infants with indications for medical intervention, such as large hemangiomas, wounds with or without secondary infection, or active trauma-induced bleeding, ...

BACKGROUND Hemangiomas, usually, present at the first few months of life and are the most common benign tumor in children. There are various therapeutic methods for hemangioma. Capillary hemangioma is a type of hemangiomas. The steps of treatment of a child with capillary hemangioma in Taleghani Hospital of Gorgan, Iran, are reported. CASE REPORT In this report, it is described an 18-month-ol...

sclerosing hemangioma of the lung is extremely rare.  herein, a case of sclerosing hemangioma of the lung in a 44-year-old woman is reported.  on admission, the patient complained of pain in the left lower neck and upper chest.  chest x-ray revealed a mass in lingular lobe of the left lung.  the patient underwent surgery and a mass was removed through left posterolateral thoracotomy.  pathologi...

Infantile hemangioma, a common benign tumor of infancy, grows quickly in the first year of life, and then regresses slowly to fibrofatty tissue in childhood. The accumulation of fibrofatty tissue in hemangioma involution indicates adipogenesis during this period. Perivascular cells (PCs) from multiple organs display multi-lineage differentiation, including adipogenesis. So we supposed that PCs ...

Infantile hemangioma (IH) is a common childhood vascular tumor. Although benign, some hemangiomas cause deformation and destruction of features or endanger life. The current treatments, corticosteroid or propranolol, are administered for several months and can have adverse effects on the infant. We designed a high-throughput screen to identify the Food and Drug Administration-approved drugs tha...
