A flat hemangioma in a baby A resolving hemangioma Infantile hemangioma, well-circumscribed red, violet, exophytic vascular tumor on the nose of a one-year-old child [17] Infantile hemangiomas typically develop in the first few weeks or months of life. [18] They are more common in Caucasians, in premature children whose birth weight is less ...
Like juvenile hemangiomas, infantile hemangiopericytomas only appear in the subcutis and affect newborns throughout their first year of life. They are characterized by being multilobulated and frequently having separate perivascular and intravascular satellite nodules outside of the main tumor mass. [2]
The most common form, seen in infants, is an infantile hemangioma, known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life. A hemangioma can occur anywhere on the body, but most commonly appears on the face, scalp, chest or back.
An additional study noted the effectiveness of propranolol in 3 infants with infantile hepatic hemangiomas and skin hemangiomas. [23] Two of the infants had cardiovascular complications and the other infant had hypothyroidism. All of the infants were given oral propranolol and saw a decrease in symptoms of the both hepatic and skin hemangiomas.
Kasabach–Merritt syndrome (KMS), also known as hemangioma with thrombocytopenia, [1] is a rare disease, usually of infants, in which a vascular tumor leads to decreased platelet counts and sometimes other bleeding problems, [2] which can be life-threatening. [3] It is also known as hemangioma thrombocytopenia syndrome.
Early recognition of this injury is crucial for survival. Infants who have experienced a difficult operative delivery or are suspected to have a SGH require ongoing monitoring including frequent vital signs (minimally every hour), and serial measurements of hematocrits and their occipital frontal circumference, which increases 1 cm with each 40 mL of blood deposited into the subgaleal space.
The most common mechanism of injury is high-speed motor vehicle accidents. The injury is more likely in children due to the large size of their heads relative to their bodies, and more horizontal orientation of the occipital condyles. It represents <1% of all cervical spine injuries. [1] Several subtypes of atlanto-occipital dislocation are known.
The occipital condyles are undersurface protuberances of the occipital bone in vertebrates, which function in articulation with the superior facets of the atlas vertebra.. The condyles are oval or reniform (kidney-shaped) in shape, and their anterior extremities, directed forward and medialward, are closer together than their posterior, and encroach on the basilar portion of the bone; the ...
