Introduction
Cherry angiomas can be removed through treatments such as laser therapy, cryotherapy, electrocautery, microwave therapy, or surgical excision. When benign and asymptomatic, they may simply be monitored. Minimally invasive methods are preferred if removal is desired. Prompt medical consultation is recommended if the angioma rapidly increases in size, ulcerates with bleeding, or affects appearance. Laser therapy: utilizes the photothermal effect of specific wavelength lasers.
Cherry angiomas can be removed through various treatments such as laser therapy, cryotherapy, electrocoagulation, microwave therapy, or surgical excision. As they are mostly benign and asymptomatic, observation alone may be sufficient. When removal is desired, minimally invasive methods are preferred. Prompt medical consultation is recommended if the angioma rapidly increases in size, ulcerates with bleeding, or affects appearance.
1. Laser therapy: Uses the photothermal effect of specific wavelength lasers to directly destroy blood vessels within the angioma, causing coagulation, necrosis, and subsequent absorption. This method allows quick recovery with only mild, temporary pigmentation as a potential side effect.
2. Cryotherapy: Utilizes liquid nitrogen to freeze the angioma tissue, leading to necrosis and shedding. It is suitable for small, superficial cherry angiomas. Post-treatment sun protection is important to avoid hypopigmentation or minor scarring.
3. Electrocoagulation: Applies high-frequency electrical current to generate heat that coagulates angioma tissue and seals abnormal blood vessels. It is simple, fast, and best suited for a small number of small lesions. The treatment site should be kept dry after the procedure.
4. Microwave therapy: Uses thermal effects of microwaves to heat and coagulate angioma tissue, thereby destroying vascular structures. This method causes minimal trauma, little bleeding, and short recovery time, with limited damage to surrounding skin.
5. Surgical excision: Reserved for large angiomas, those with recurrent bleeding, or suspected atypical changes. Complete surgical removal ensures eradication of the lesion, followed by wound suturing. Although definitive, this approach leaves a linear scar.
In daily life, avoid scratching or rubbing the area with angiomas. Use lukewarm water when bathing, wear soft clothing to minimize irritation, apply sun protection when outdoors, and regularly monitor the lesion for changes to reduce external influences.
