Introduction
In general, blood moles may be caused by natural skin aging, hormonal changes during pregnancy, hepatitis, thrombocytopenic purpura, hemangioma, or other factors, and appropriate management depends on the specific situation. If a blood mole is detected, avoid physical impact or friction to prevent rupture and bleeding. If the number or size of blood moles increases significantly within a short period, prompt medical consultation is recommended for accurate diagnosis and targeted treatment.
In general, cherry angiomas may be caused by natural skin aging, hormonal changes during pregnancy, hepatitis, thrombocytopenic purpura, hemangioma, and other factors, requiring different management approaches depending on the specific cause.
1. Natural skin aging: With increasing age, the physiological functions of the skin gradually decline. Slowed metabolism leads to local accumulation of metabolic waste, which may stimulate blood vessels and promote the formation of cherry angiomas. It is recommended to use mild skincare products with moisturizing and antioxidant properties in daily routines to delay skin aging.
2. Hormonal changes during pregnancy: During pregnancy, levels of estrogen, progesterone, and other hormones increase significantly in women, causing dilation of small blood vessels on the skin surface, leading to the development of cherry angiomas. These typically fade gradually after childbirth as hormone levels return to normal and usually do not require specific treatment.
3. Hepatitis: When liver function is impaired, the liver's ability to inactivate estrogen decreases. This results in relatively elevated estrogen levels in the body, which can cause capillary arteriolar dilation and subsequently lead to cherry angiomas. It is recommended to treat the underlying condition under medical supervision using medications such as lamivudine tablets or adefovir dipivoxil tablets.
4. Thrombocytopenic purpura: In patients with thrombocytopenic purpura, reduced platelet count or impaired platelet function makes blood vessel walls more susceptible to damage. Blood leakage into the subcutaneous tissue may form petechiae or ecchymoses that resemble cherry angiomas. Treatment under medical guidance may include medications such as prednisone acetate tablets or intravenous immunoglobulin.
5. Hemangioma: Hemangioma is a common benign vascular tumor. Abnormal blood vessel development during embryogenesis leads to excessive proliferation of local vascular tissue, forming a hemangioma that may appear similar to a cherry angioma. Treatment options under medical supervision may include laser therapy or cryotherapy.
If cherry angiomas are noticed, avoid physical trauma or friction to prevent rupture and bleeding. If there is a sudden increase in number or size of these lesions over a short period, prompt medical evaluation is advised to establish an accurate diagnosis and receive appropriate treatment.
