An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. [1] [2] Other names include capillary hemangioma, [6] "strawberry hemangioma", [7]: 593 strawberry birthmark [8] and strawberry nevus.
A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. 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 ...
The health effects of benign tumor growth may be more prominent if the tumor is contained within an enclosed space such as the cranium, respiratory tract, sinus, or bones. For example, unlike most benign tumors elsewhere in the body, benign brain tumors can be life-threatening.
As with any type of tumor, brain tumors are an abnormal growth of cells, the number of which will determine, in part, the overall size of the tumor. In the case of benign brain tumors, these cells ...
Symptoms may be minimal if the tumor is small. [2] A testicular teratoma may present as a painless lump. [1] Complications may include ovarian torsion, testicular torsion, or hydrops fetalis. [1] [2] [3] They are a type of germ cell tumor (a tumor that begins in the cells that give rise to sperm or eggs).
Lymphatic malformations are rare, accounting for 4% of all vascular tumors in children. [7] Although lymphangioma can become evident at any age, 50% are seen at birth, [ 12 ] and 90% of lymphangiomas are evident by 2 years of age.
In the case of schwannomatosis and neurofibromatosis, tumors can grow on or close to nerves anywhere in the body. Frequently, there are several tumors. [8] The typical symptoms involve a combination of pain, loss of nerve function, and/or a palpable (or radiographically apparent) mass affecting a peripheral nerve. The etiology and importance of ...
Benign sacrococcygeal teratomas are more likely to develop in younger children who are less than 5 months old, and older children are more likely to develop malignant sacrococcygeal teratomas. The Currarino syndrome , due to an autosomal dominant mutation in the MNX1 gene, consists of a presacral mass (usually a mature teratoma or anterior ...
