Does melanoma need to be excised?
Melanoma is a type of malignant tumor, which mostly develops from common melanocytic nevi. Once diagnosed with this disease, surgical removal is necessary. After the surgery, a full-body examination is also required to check whether the tumor cells have metastasized. If there is metastasis, further radiotherapy or chemotherapy is needed. If melanocytic nevi appear on the body, it is crucial to handle them properly, ideally by using laser treatment or surgical removal when they are relatively small to prevent the later formation of melanoma. If the melanocytic nevi cause pain, itching, or oozing after scratching, it might be a precursor to malignancy, and formal treatment is necessary.
The term "progressive stage of vitiligo" refers to a phase in which the skin condition vitiligo is actively spreading, with new patches forming and existing patches expanding.
The progression phase of vitiligo, also known as its development phase, is characterized by the enlarging and whitening of the skin patches. This phase primarily signifies that the patches are expanding and becoming more pronounced in color. Vitiligo is related to factors such as reduced immunity, genetic heritage, copper deficiency in the body, or local injuries. Through proper treatment, the progression phase can gradually shift into a recovery phase, where melanin increasingly covers the white patches. Some patients may enter a stationary phase where neither medication nor lack of treatment changes the condition of the vitiligo; typically, if there’s no change for over a year, it enters this stationary phase. If it is determined that the vitiligo is in the progression phase, prompt treatment is crucial to prevent the condition from worsening, which could make treatment more difficult.
Can scrotal eczema heal on its own?
Scrotal eczema is a type of eczema that is caused by allergies. This condition generally does not heal on its own without treatment; rather, it may progressively worsen, becoming increasingly itchy. Repeated scratching can potentially lead to the scrotum rupturing, exuding, or becoming infected. It is essential to treat scrotal eczema through formal medical channels. Treatment may include taking oral and topical anti-allergy medications. It is recommended to gently wash the affected area with lukewarm water, avoid using hot water for washing, abstain from consuming spicy and irritating foods, avoid staying up late, and steer clear of public baths and swimming to maintain good hygiene in the affected area. Keeping the area ventilated and dry can also be beneficial to the condition. After the eczema is healed, it is important to prevent a relapse by enhancing physical fitness, sweating more, and bathing more frequently.
How to treat sebaceous cysts?
Sebaceous cysts are a type of benign proliferation related to vigorous sebaceous gland secretion and bacterial infection on the skin surface. These cysts feel relatively soft. The most common treatment is a minor surgery at a dermatology department of a reputable hospital to completely remove the cyst. Generally, oral and topical medications are ineffective against sebaceous cysts. If left untreated, the cyst may continue to grow, causing pain and even rupture. Therefore, once detected, it is crucial to seek timely treatment. After treatment, it is important to adopt healthy dietary and lifestyle habits, avoid spicy and irritating foods, refrain from staying up late, and avoid soaking in public baths or swimming, and try not to keep pets at home.
Why does acne recur repeatedly?
Acne is a disease caused by overactive sebaceous glands and infection of the skin surface with Propionibacterium acnes. The most common symptoms are the appearance of red papules on the face, which are quite painful, and some directly develop pus heads. Although this disease can be completely cured through formal treatment, it has a high recurrence rate, and the main factor of recurrence is related to one's age group, especially during adolescence and in patients with hormonal imbalances. During the treatment period, it is necessary to avoid spicy and irritating foods for a long time, try not to stay up late, avoid anxiety and tension, and refrain from misusing cosmetics, especially greasy products that can clog pores. After recovery, it is advisable to wash the face with cold or cool water, and avoid using hot water.
How to eradicate common warts
Common warts are caused by human papillomavirus infection. This disease is contagious and recurrent. Currently, the most common treatment is cryotherapy with liquid nitrogen. Generally, small warts can often be completely removed with one treatment. Slightly larger warts may require two to three, or even three to four cryotherapy sessions, but they can ultimately be completely cured. Clinically, a topical remedy called Wart-Off can also be used to completely cure the warts, although this method may take a longer period. During the treatment period, avoid consuming spicy and stimulating foods, as they may cause the virus to grow more rapidly. Try to avoid scratching the affected area, as this behavior could potentially spread the disease and lead to more growth. It is also important to protect the normal skin during treatment.
Severe symptoms of papular urticaria
Papular urticaria is a type of allergic reaction associated with direct contact with irritants or bites from mosquitoes and fleas. Generally, this condition does not cause severe symptoms. Most commonly, it results in red papules and severe itching on the body, with occasional small blisters. If these blisters burst, disinfection with iodine can prevent infection. In some cases, if the blisters are large and burst, leading to infection, this may cause fever or other symptoms that require symptomatic treatment. It is advisable to frequently expose clothes, bedsheets, and covers to sunlight for disinfection, and to avoid keeping small animals at home or visiting areas with dense vegetation.
How long does it take to cure tinea cruris?
Jock itch is caused by a fungal infection. The fungus attaches to the skin surface at the root of the thighs, and some fungi can go deeper, so the treatment period is generally longer. Commonly used antifungal creams must be applied for a long treatment period, at least one month or even more than two months, to completely cure the condition. This disease can be entirely eradicated, but it does have a certain recurrence rate. For example, recurrences can occur if after healing, one often goes to public baths or swimming pools, or if one has athlete's foot, washes socks and underwear together, has pets at home, lives in damp and hot conditions, or bathes infrequently. Therefore, standardizing one's dietary and living habits, maintaining hygiene, and bathing more frequently can help prevent recurrence.
Papular urticaria causes and symptoms
Papular urticaria is a type of allergic reaction, which is specifically related to exposure to irritants, or bites from mosquitoes and fleas. The cause of this disease is relatively clear. Generally, the main symptom is the appearance of red wheals on the body with clear boundaries. At the center of the wheal, there may be a puncture point or small blisters. The primary symptom is itchiness, which is often severe. Repeated scratching of the small blisters can lead to rupture and infection. Therefore, it is important to treat this disease as soon as it is discovered, using oral and topical anti-allergy medications, which generally subside within about a week. It is also advisable to avoid keeping small animals at home and to frequently disinfect bedding by exposing it to sunlight. (Medicine should be used under the guidance of a doctor, based on specific circumstances.)
Can you eat vitamins for tinea pedis and tinea manuum?
Athlete's foot is a disease caused by fungal infections and is not related to a lack of vitamins. However, supplementing with vitamins appropriately during treatment can be helpful. This disease is highly contagious and recurrent, and once identified, it must be treated formally. It is recommended to visit a dermatologist at a reputable hospital for confirmation before treatment. Antifungal creams can be applied topically twice a day, and the treatment should be maintained for at least one to two months to completely kill the deep-seated fungi and prevent recurrence of the condition. It is advisable to avoid keeping small animals at home, avoid contact with dirty water and soil, and refrain from using public baths and swimming pools. Bath towels and washcloths should be used separately from those of other family members.
