This approach is effective mainly for superficial, small-sized infantile hemangiomas. The medication can penetrate locally, inhibit vascular proliferation within the hemangioma, slow down lesion growth, and even promote gradual regression. These hemangiomas are typically located in the superficial skin layers, allowing the drug to fully reach and act on the lesion. This treatment is commonly used in clinical practice as a standard intervention for such hemangiomas.

The consequences of untreated infantile hemangiomas may generally include effects on physical appearance development, increased risk of infection and ulceration, compression of surrounding tissues, bleeding risks, and impaired functional development. Impact on appearance: If a hemangioma develops in exposed areas such as the face or neck, it may gradually enlarge with age, deepen in color, or become raised, potentially leading to permanent pigmentation or scarring, thus affecting the child's physical appearance.

In general, whether a small red vascular spot (hemangioma) on the arm is dangerous depends on the specific circumstances. Small hemangiomas that remain stable in size and cause no discomfort are usually not dangerous, whereas larger ones, those that grow rapidly, or those accompanied by symptoms may be more concerning. In daily care, avoid repeated friction or pressure on the hemangioma site, and wear loose, breathable clothing to minimize irritation.

In general, the severity of a hemangioma under the tongue needs to be determined based on specific circumstances. Hemangiomas that are small, cause no discomfort, and do not affect eating or speaking are usually not serious. However, larger hemangiomas that cause discomfort or impair function may be more serious. In daily care, it is important to avoid consuming food that is too hot or too hard, and to minimize friction and irritation to the affected area.

Commonly used medications for injection therapy of hemangiomas include Pingyangmycin injection, Polidocanol injection, Triamcinolone acetonide injection, Bleomycin injection, and Sodium Morrhuate injection, which should be administered by a qualified physician. If a hemangioma rapidly enlarges or develops ulceration and bleeding, prompt medical attention is recommended. Pingyangmycin injection: inhibits the proliferation of hemangioma endothelial cells.

A more favorable scenario is when calcification occurs during the natural course of a hemangioma, as the blood vessels within the lesion gradually undergo fibrosis and calcification, leading to cessation of growth or slow regression. This process reduces the risks of bleeding and ulceration. Such calcifications are typically localized, without accompanying compression of surrounding tissues or symptoms, representing a sign of spontaneous improvement of the hemangioma.

Surgical intervention may be necessary in cases where the hemangioma is located in a special position, such as near the splenic hilum, areas with dense vasculature, or adjacent to surrounding organs, as these are prone to external forces, enlargement, compression of surrounding tissues or blood vessels, leading to abdominal pain, bloating, and even risk of rupture and hemorrhage. Even if the hemangioma is in a relatively favorable location, a large tumor volume may impair splenic function due to mass effect, and such cases should also be considered for surgical treatment.

Conditions that may involve the entire body often require systemic imaging examinations, which can scan tissues and organs throughout the body to detect hemangiomas in various locations, such as subcutaneous tissues and internal organs. These examinations are especially suitable when multiple hemangiomas are suspected or a comprehensive assessment is needed. However, such imaging may miss some small hemangiomas due to factors like their tiny size or hidden locations.
